WNDR3700v3 Netgear - Intermittent Loss Of Connection

Jul 17, 2012

I've been having a problem for a while now wherein my internet connection seems to randomly drop for anywhere from ten seconds to a minute, then come back online. It's been doing this over the lifespan of one router, and continued into the life of this new one I have, which is a WNDR3700v3 Netgear.

I called my ISP and they fiddled around with things on my computer, but the issue is still going on. Rather than slog through another three hours with them, does anyone here have any tips for what I might look into for the cause?

D-Link DIR-655 :: Intermittent Internet Connection Loss And Video Streaming Stopped?

Jan 10, 2012

I am having wireless connection/internet issues that are irritating me to the core!!! I have called tech support 4 times now, and I still can't get everything to play nice...I have the 655 set up as a wireless router to a Windows 7 laptop, one iPad, two iTouches, and one N3DS. I can't find a setting that will work with all devices. Here are the senarios...

1) Settings: Wireless enabled, 802.11n only, Auto Scan off-channel set to 1, Best Transmission rate, Channel Width Auto 20/40, Visible, Auto WPA Mode with AES Cipher and a pre-share key. This yields fantastic results with my laptop, it can stream video for entire episodes, and I have no problems with loading webpages in either IE or Firefox. However, it does not support the kids iTouches or N3DS.

2) Changed the above to mixed 802.11n/g AND ALSO tried 802.11 only: iTouches work and can connect to the internet, but laptop doesn't like it. I get "Problem loading webpage" every other time I access and website, and streaming stop every 5-6 minutes. Bars indicate wireless signal is strong, but intermittently get that yellow triangle.

Netgear Wndr3700v3 Router - Constant Small Lag Spikes

Jun 3, 2012

I've been having this issue with my wireless connection for quite a few months now and up until now I've just dealt with it. With the release of Diablo 3 (whoo!) it's become unbearable with this lag spikes. My ping will be fine, steady around 50-90 but then randomly spike upwards of 400. After a few moments (literally a second or two) it'll drop back down to it's normal speed. This happens in all online games I play, WoW, League of Legends, DotA 2 and now Diablo 3, I have roadrunner and pay for 25 download and 1 upload so it should be more than enough to play the games I'd like, I'm also running on windows 7. I think part of the problem could be the fact that the router is in the basement and I'm on the second story. I have a netgear wndr3700v3 router and I set up a repeater in my room to see if that would work (asus rt-n12 router) and although it has increased my speed, I still have these ping spikes.

Intermittent Loss Of Internet

Oct 10, 2011

My PC is connected to a network with my company. My PC, only my PC, seems to get random and quick drops in internet connection but the connection to the network/domain remains active.

1 - Open Internet Explorer
2 - Receive "Cannot Display Webpage" message.
3 - Refresh page quickly and the page shows up.

sometimes step 3 takes 3 or 4 times, seems to be getting worse as the problem has been around longer, but most of the time a quick refresh works. Same thing happens with Pandora, my standalone player for Pandora will lose connection but come back with a quick "RECONNECT" button.So, as you can see, it's only dropping out for seconds, 1 - 30 seconds at the most, my thouoght is the Ethernet card??

Pending Intermittent Network Loss

Jan 12, 2011

Running 5 PC's and a laptop on a wired/wireless network at home. One PC running Win XP Pro started dropping the network connection (so it appeared) during browsing. Have found the following:

1. MSN messenger runs fine, and doesn't drop out
2. AVG antivirus updates with no issues
3. Web Pages in Chrome and IE will load fine one minute, then cannot load or pause for 1-2 minutes while loading
4. Can ping web addresses/IP addresses from command prompt with no issue.
5. Have changed the network connection from Ethernet to Wireless, which makes no difference to the issue.
6. If I "repair" the connection, and the network refreshes the IP address, I can browse successfully, for about a minute, before the issue occurs again. "Repair connection" again and can browse again for a minute.
7. Checking connected devices to the Netgear router, shows the PC name sometimes, against the IP address, other times it shows the PC as "unknown" against the PC address (when this occurs, web browsing is lost)
8. All other PC's on the network are fine.

Cisco Switches :: SG300-28P (SRW2024-K9) In L3 Mode - Intermittent Loss Of Speed

Jan 24, 2011

Every "once in a while" (about a week with my network load), the SG300 crawls to an almost standstill of all IPv4 activity (haven't got IPv6 enabled here yet, so I can't comment wether this applies to IPv6 as well). It seems pure L2 transmissions is not affected, but L3 definitely is (down to 20mbit as opposed to the 600+ rate I usually get).
 
Soft-rebooting the switch (via the webgui) useful, and the intervals of the crashes seem related to total bytes transmitted, not time. I have jumbo frames enabled, and disabled flow control on on the switch and all hosts.
 
Firmware Version is 1.0.0.27, md5 1987292110f5657e74308dde30c03dc4 Boot Version is 1.0.0.4 md5 4c9a0b6a9f1346736646d08ab94ae2ac

Lately I encountered random Internet connection issues?My router is a Netgear Wireless ADSL Firewall Modem Router DG834 (Firmware V1.05.0) and my ISP, isn't the most reliable regarding bandwidth... All clients (max 3 at the same time) connect wireless.The problem is that the last few weeks my connections is very unstable, all clients lose the internet connection until you restart the router manually.I can't even connect to the webinterface (192.168.0.1), during the downtimes.

Persistent Internet Loss Through Netgear DG834N

Feb 5, 2011

I have a recurring problem that only started happening for the last 3 weeks or so.I keep losing my internet. In event viewer it shows up as: "none of the default DNS Servers responded".I am using a Netgear DG834N Modem/Router ADSL LAN to the first computer and a Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller on my ASUS P6X58D-E motherboard.I have been using this setup since June 2010 with no problems.I am using Windows 7 Home Premium 64 bit.I have 2 other computers and a Sony PS3 connected wirelessly to this Netgear Router, but one of the computers is hardly used now. I Googled this problem and it came up with a registry fix which seemed to solve some of the problem, but it seems to have come back just as bad today, so changed the registry value back to what it was before.

NetGear WNR3500L - Toshiba Satellite A500-027 Packet Loss

Jun 11, 2011

I just found out I was having packet loss with my toshiba satellite. I have a NetGear WNR3500L freshly installed because the old router (d-ling dir 615) was dropping the connection all the time so we changed it, But now I'm still having problems of lag so I'm well ill do some tests, find out I lose packets so i blame it on the router but then i make the same test on a wired computer wich didnt lose any packets at all. I came to the conclusion it had to be my pc, i did the test both while be wired and wireless.

Intermittent And Inconsistent Internet Connection

Dec 5, 2011

My laptop is connected to an Internet cable inside my apartment building for access to a free Internet service provided by the building management.The high speed cable service works okay for a few days but then after say 4 or 5 days it starts to slow down and then on the 6th or 7 day I can no longer connect using the cable. The technician in my building doesnt speak such good English and claims it is a software problem in Windows itself in my laptop ,but I don't know what would cause the software to trigger this condition?The last time the technician told me to go through some steps but I have to admit I have forgotten the very last ones in the " procedure " and how to complete the final steps of the procedure :-

He said to :-

1. Right click on the computer icon on the desktop

2. click on device manager

2. click on " network adapters " these are shown as being " Atheros AR8152/8158 PCI-E Fast Ethernet Controller ( NDIS 6.20 ) and secondly " Realtek RTL8188CE Wireless LAN 802.11 PCI-E NIC "

4. After that he told me to " refresh " the connection but I have forgotten how to do so?The wireless connection is working okay but I have noticed once this fault happens to the cable connection, the wireless connection doesn't work either until I unplug the cable. Then I can connect to the wireless Internet connection. But if I leave the cable in then neither the cable or the wireless works?

Intermittent Browser Connection To Internet

Apr 12, 2011

I work in a small school and recently we started to have a problem with browsing the internet. We don't have an 'IT Department' as such as I'm the closest thing to it.When a browser is opened it will not connect to the homepage, or if it does its generally from cache, instead an error message about not being able to connect to server will appear. Now if you hit refresh you might or might not connect to the webpage in question but you can gurantee that it will take a long time to make that connection even on an undemanding site like wikipedia.The odd thing is that when connected to a speed checker it gives no surprising results, speed is normal. Also when downloading a file or the latest linux live distribution torrent I can achieve maximum speeds available to us.We use a selecction of Macs & PCs mostly connecting through ethernet cabling although connecting wirelessly is no different. We use BT 2Wire 2700HGV Business Hubs. I can't think of any changes our end that have happened to cause this and our internal network connections run just fine. I have tried pinging from the command line and it looks ok to my limited expertise, no lost packets.

Intermittent Internet Connection In A Technicolor Tg582n Pro

Jan 5, 2013

I was previously with sky and never faced any bother with my wireless broadband. Recently to my regret we moved broadband (amongst other utilities)to Utility Warehouse (UTW) who's broadband is through Telecom Plus. Anyway since joining with them I have had no end of bother with intermittent internet connection. Sometimes we get a stationary green broadband light then after a little while then we get a flashing green broadband light. We are constantly either pin resetting the router or switching it on and off at the rear, where it will work for a small amount of time then connection is lost again. The router that they have given us is a technicolor tg582n Pro. We have had two of these as originally we thought that the router could be faulty but obviously that is not the problem as even the second one is dropping our connection. We bought another filter incase that was the problem and even tried plugging router directly into phone box and still didnt work. Utility Warehouse have been about as much use as a chocolate teapot and we are so <unhappy> that we are paying for a service that does not work? They said that our cordless phones could be interfering with the signal? Is this maybe the case and the phones are running on same channel as router thus causing interference? We had these same phones when we with sky and they never caused interference with our broadband. I was going to try connecting my laptop via ethernet cable to router. Sometimes the landline crackles (since UTW installed a new landline & new tel number) so it could even be that? UTW will not send an enginneer out to check their line. we are at our wits end, about to cancel their broadband and go back to reliable sky.

Belkin N600 Router Intermittent Connection To Network

Oct 15, 2012

I have a Compaq with XP wired on a Network with a Belkin N600 Router.There are 5 computers on the Network, (4 wired, one wireless) and this is the only computer that I have problems with connectivity. It connects to the Belkin through 2 switches.Typically when I turn the system on it connects, downloads mail, etc. After a short period of time there is no connectivity to the network for printing nor the internet.I may get connectivity randomly again after a while, but you never know if or when you will get connectivity again for sure. I am using Explorer.I had loaded some Belkin software with no luck so I uninstalled it. The other computers have no special software for the router.

TP-link TL-WN722N / Intermittent Wireless Connection Timeout

Jul 14, 2012

I've been running into an issue for the past week or so where my wireless adapter intermittently can't contact my router.When it occurs the network connection reads as having limited connectivity. I'm unable to send requests to load webpages, and videos and the like stop loading. Sometimes the network disconnects entirely. After this occurs, I can't connect again for a few minutes. My connection consistently reads as having 2-3 bars available. The issue tends to occur frequently, often every 15 minutes or so. Strangely enough, I have been able to play bf3 online for over 40 minutes without connection problems (I quit before any occurred - not sure if any would have). So far I've tried the windows troubleshooter, updating the driver to my wireless networking adapter, manually assigning my network address (tried 192.168.1.4, 192.168.1.5, etc), setting my 802.11b preamble to "Long only" and performing a system restore. I have rebooted my machine as well.

My technical specs are as follows:I'm running Windows 7 Ultimate N 64 bit edition with service pack 1. System has 8gb Ram, an i5-3570k processor and HD7850 graphics card. Motherboard is the Asrock Z77 extreme 4. My wireless network adapter is the TP-link TL-WN722N. The adapter was working fine for some time before this issue appeared.My router is an old U.S. Robotics Wireless MaxG Router. It seems to work fine with other computers in the household, although it does require fairly frequent power-cycling. Running ipconfig on the command prompt while the internet is working returns:

Quote:

Dell :: Intermittent Wi-Fi Connection On New Inspiron 1506 Desktop

Jan 29, 2013

I have a Dell Inspiron desktop with Dell Wireless 1506 802.11b/g/n  card.  This PC is fairly new - purchased in October 2012.  Most of the time the wireless connection is fine, although the signal is weaker than it should be (about 2 bars).  Occasionally however the wireless signal drops to one bar or less, or is completely lost.  The result is loss of internet connection.  Restarting the PC will often restore the connection, although the signal level remains low.  This is very surprising as other 802.11b/g laptops and PCs, sitting on the same desk in the same room, will show a strong wireless signal of 4-5 bars.  I have measured the wireless network strength in that room using a laptop with inSSIDer and it seems just fine.  So I don't believe the problem is in the wifi signal strength.

The wireless access point is a Motorola surfboard b/g cable modem that is located about 25 feet from the Dell PC.  That cable modem is reporting excellent signal levels on the coaxial cable to the street, so the problem is not in the access point.  Connection speed when tested from other PCs/laptops on that network is just fine.

I am wondering if there is some sort of intermittent hardware problem in the Dell wireless adapter that might be causing this problem.  Or some sort of software conflict.

Cisco VPN :: 3560 - Getting Intermittent Connection To Internal Resources

Dec 14, 2012

I have an intermittent issue happening on my company's firewall, and I'm at a loss as to how to troubleshoot further.
 
We recently made some changes to our network, which included moving an ASA 5505 from one location to another. In moving this we also connected it to a different switch. It used to hang off a Cisco 3560, and now it hangs off a ProCurve 5406zl.
 
The setup is that the ASA is connected on two ports to the HP, which is simply a layer 2 device sitting between the firewall and the uplink to our ISP. One port, e0/0, is the outside interface and is set to switchport access vlan 2. The second interface, e0/1, is set for vlan 1, also access mode. It has an IP of 10.0.0.2. The HP on the other end of that has an IP of 10.0.0.1. So outside VPN connections come through the HP to the ASA on e0/0, and back out the ASA on port e0/1 to reach devices on the internal network.
 
What happens is that when a user connects to the VPN, they can reach internal resources intermittently. For example, I tried to ping an internal server IP address (let's say 10.0.0.23) from my laptop, while on the VPN, and pings failed. However I could ping that IP from the ASA itself. Another example is that during one VPN connection I was unable to connect to an internal web server, but once I disconnected and connected ahain I could reach the server fine.
 
The intermittent nature of the problem made me think that it could be an ARP issue, that somehow the traffic is getting sent back out the wrong interface sometimes, hence the lack of communication. However when I did show switch mac-address | include mac address, using the base mac of the HP, I only saw the mac address of the HP on one interface, e0/1. That makes me think that things are working as they should. Although I guess maybe it should appear on both interfaces...? I don't know. How I can most effectively troubleshoot this? It seems like the symptoms are indicative of some kind of rookie mistake, but for the life of me I can't figure out what it is.

Linksys Wireless Router :: Intermittent Wifi Connection With Wrt54g2 V.1?

Apr 25, 2012

My router has been dropping the internet connection for years. The ethernet connection to the desktop works fine all the time. The problem is only with the wireless connection. About every 1/2 hour or so the router will drop the wireless connection and neither or my 2 laptops can find the network. Unplugging the router and replugging it in solves the problem temporarily, until it drops it again. I updated the firmware to 1.0.4 and that yielded no changes.
 
Router: WRT54G2 v.1 Modem: Siemens Speedster 4100 (part #060-D141-A12) My two laptops running wirelessly are Macs. The desktop is PC running Windows Vista.

Cisco Wireless :: Intermittent Connection To Network Using 1242 AG Access

And, even if I connect to the network, I cannot get a DHCP address for the client.Other devices connected (but not through this Access Point) to the associated VLAN 60 can get a DHCP address and connect just fine.Here is the configuration for the Cisco 1242 AG access point in question: [code]

Lastly, here is the information on VLAN 60 from the distribution switch. As mentioned, other devices connect to this VLAN and get IP addresses just fine.

D-Link DAP-1522 :: A1 In Bridge Mode Intermittent Wireless Connection Drops?

Apr 21, 2013

I have a brand new DAP-1522 A1 connected to an 802.11n wireless LAN in bridge mode. Running in the 2.4GHz band with WPK-2 and AES security/encryption.Everything runs fine 99% of the time, but once a day or so the wireless LAN connection on the DAP-1522 drops and then takes about two minutes to re-connect.  It re-connects and then everything is fine for a day or so until the next dropped wireless connection episode on the DAP-1522.  I know my 802.11n wireless network is 100% fine as during the dropped connection to the DAP-1522 I can connect directly to the 802.11n wireless network (running from my gateway/router) using my other computer, no issues.I've seen some posts on this forum that the A1 version of the DAP-1522 hardware is not 100% compatible with the 802.11n network standard and there will be intermittent wireless drops.  If this is true, it's just insane.  All I can say is I can't believe DLink would allow a product to be sold that won't work properly on 802.11n networks.I check the logs each time I see the dropped wireless connection and all that shows is the following.1) Negotiating connection   2) 4-way handshake success [mac address]There's no message in the logs about why the wireless connection dropped, but I assume it has something to do with re-newing a key for the wireless network as the successful key renewal messages are the only other messages in the log.  When the wireless network dropped I don't see the successful key renewal message at the time I should see it.I thought this DAP-1522 would take 15 minutes to configure in bridge mode and then I'd forget about it.  Spend too much time on this already, so a bit disappointed with this DAP-1522 and DLink tech support....though when it's connected to the 802.11n wireless LAN it works fine.

Linksys Wireless Router :: WRT120n - Intermittent Connection For Apple Devices

Dec 3, 2011

I recently upgraded my Linksys wrt120n router firmware & had to reconfigure settings.  Subsequently, some (but not all) of my apple devices are having intermittent wireless connection problems.  Specifically, my ipad1 & ipad2 never lose their connection but a mac book pro (~ 2 years old), iPhone 3g, iPhone 4, older iPod touch & very old i book g4 all work for a period of time (usually 1/2 day) & then lose their connection.  When I attempt to reconnect these devices I receive the following error..."unable to join the network xxxxxx....".  I also have a Dell laptop (1 1/2 yrs old) that generally does not have the connection problem.  Finally, when the devices do lose their network connection all I have to do to reconnect is go to the Linkys router setup webpage & click on save & the wireless connection works again (almost like this is just refreshing the connection for these specific apple devices).  I was not having any problem prior to the firmware upgrade & from what I have read the older firmware version is no longer available so going back to the old firmware does not appear to be an option.

Loss Of Internet Connection

Jan 26, 2011

I support a small business with 6 computers(XP) wired networked to a Cisco router and connected to an ADSL WAN. For over a year now they have experienced an overnight loss of Internet connectivity requiring the router to be rebooted almost every morning. We thought it was a fault router so we replaced this with a good Cisco router, but the problem persisted. We got Cisco involved and they monitored it without finding fault, but they replaced it anyway. We also replaced our ISP but all without avail. I use a combination of pc.Any where and Log mein to support them over the web. The strange thing is that I am always able to connect to their system, but when the fault is apparent, I can't get web access to their router internally or externally and they can't get Internet or e-mail access. The router is my DHCP server and each PC is DHCP mapped in it. Cisco have looked at all the settings of the router and they say they are good.

Random Connection Loss On Desktop?

Oct 25, 2011

While I am connected to the internet, whether surfing the web or playing a game, I randomly get disconnected with a "No Network Connection" error on the network access icon on my toolbar. However, other computers that are networked (both wireless and wired) do not receive a disturbance in the connection. When I refresh or look for a new connection, I continue to get the same error and the troubleshooting tools fails to find a fix. The only way this seems to fix is rebooting the computer. Sometimes it happens multiple times in a row, but consistently happens between 1-2 times a day.I don't know if this is a coincidence or not, but it seems to happen when I'm doing stuff that could "stress" the connection, like downloading something or running a game while also browsing the web[CODE]

Frequent Loss Of Network Connection?

Nov 22, 2011

I keep losing connections to the internet and getting a couple of different messages that the Gateway IP address is invalid. There are times it happens every few minutes and other times I can go for a couple of days without it. Also, we have to have satellite internet which has such an inconsistent speed. Is it the internet speed inconsistency or the 4 year old Belkin N Router?OK, so I tried to copy the information from the CMD window, but I can't get it to work. After I got the information and right clicked and clicked "select all" then what. I couldn't copy it. I can't find my way back to the instructions.

Periodic 30 Minutes Connection Loss

Jul 27, 2012

For the past day or so I have been having problems with my internet connection to my PC. It has been working fine for a few hours, then it suddenly goes down for up to 30 minutes, with sporadic (lasting about 30 seconds) reconnection during that 30 minute period.I am pretty certain this is a computer related issue (as opposed to a problem with the modem), as none of the other computers in the household. (Ihave been affected, and neither has the wifi (I have browsed on my phone while the internet on my computer was down, in fact am currently writing this post on the wifi while my computer has no access)My computers specs (Taken from the sys info program when I regained connection for a short while) [code] Steps I have already taken in an attempt to solve this problem

1. Reset modem (turned it off and back on again)
2. Ran most of a virus scan in both macafee and avg (they both got to about 85% and by that point were just scanning steam stuff
3. Talked to a verizon tech, confirmed it is most likely not a modem problem (he didnt know what the problem was however)
4. Changed out the ethernet cable, the new one works no better than the original

Additional note: Earlier today (after these problems had begun) I was downloading the latest version of hamachi from a site soft32.com when I recieved a trojan warning from macafee. I immediatly stopped the download, restarted my computer and began scanning with both AVG and Macafee, neither found anything of note (AVG found something it labeled a hidden directly, I looked it up and it seems harmless)

Cisco :: Connection Loss Of 1310 Bridge?

May 20, 2012

I have cisco 1310  bridge  with IOS version  Version 12.3(7)JA5. Sometimes bridges are disconnecting by showing the following error message.

*Mar 1 01:22:21.856: %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 003a.99eb.cc00 Reason: Previous authentication no longer valid
*Mar 1 01:22:22.115: %DOT11-4-MAXRETRIES: Packet to client 003a.99eb.cc00 reached max retries, removing the client

[Code]....

Once it is deassossiated, ihave to manually restart the bridges. How can avoid manual restarting so it would automatically associate after some time.

Broadband :: Packet Loss And Slow Connection On Mozilla?

Apr 22, 2011

My internet connection has suddenly turned really slow and pingtest.net tells me I have severe packet loss, which makes sense as nothing will stream or load properly. I'm running Mozilla Firefox (newest version) and have tried all the usual diagnostics and resetting everything?

Sudden Loss Of Wireless Connection Linksys E3200?

Oct 31, 2012

My Linksys E3200 has no wireless access to the internet. Wireless devices show they are connecting to the router, but cannot access the internet.

The router had worked fine until suddenly no internet access. Mac network diagnostics show that the connections are correct until the ISP and Internet which show either yellow or red.

The router's homepage shows no changes in configuration. Ethernet connection works fine.

DIR-615 3.11NA Firmware / Periodic Loss Of Internet Connection?

Jun 27, 2011

Hardware: DIR-615 @ 3.11NA firmware

Wired:
PC windows 7
PS3

Wireless:
1 DELL windows 7
2 HP windows 7 (HPa and HPb)
3 smartphones

Description:Everything wired always works, the dell wireless always works and HPa always works along with all of the cell phones. HPb will connect to the router always, as in it see's the router and connects using AES security. For between 15-30 minutes everything will work correctly, transfer speeds are fast and everything is working. For no reason the laptop will lose "Internet connection" only, NOT the connection to the router. But all of the over devices continue to work correctly, so i know the router has internet connected.i would have to disconnect from the router and reconnect and that gives me another 15-30 minutes of connection. I have checked a load of stuff, but i cannot figure it out. Here is a netBIOS

C:UsersCat>NBTSTAT -n
Local Area Connection:
Node IpAddress: [0.0.0.0] Scope Id: []
No names in cache
Wireless Network Connection:
Node IpAddress: [192.168.0.15] Scope Id: []

[code]....

D-Link DI-524 - Bizarre And Very Specific Internet Connection Loss

Sep 21, 2012

Yesterday (Friday, September 21, 2012), my Internet connection started acting up. After some testing, I confirmed a very specific and baffling set of symptoms: Internet connection goes away every 25-35 minutes (I did not confirm the exact interval, but it seems to be about 30 mins.)Only some protocols are affected; HTTP*, P2P, etc. stop working; FTP, etc. continue to work When it’s stopped, cannot even ping router or cable-modem IPs or view their firmware pages Domain-names and IPs are irrelevant (for protocols that stop working, neither work, for those that still work, both work)Resetting router fixes it for another 30 minutes Keeping the connection idle or active doesn’t seem to make a difference (nor the bandwidth usage in that period)Connecting directly to cable-modem allows it to work indefinitely Disconnecting the router from the cable-modem works indefinitely (no Internet connection obviously, but can still access router IP and firmware page)Connecting the router to the cable-modem, but putting the modem on standby also works indefinitelySame problem with both a wireless laptop and wired (on any port) desktop (both Windows 7; will try to test Windows XP when possible)Nothing had changed in the days leading up to the issue. No modifications to the networking configuration or the router; there were not even any Windows updates except for an MSSE definition update.Waiting does not fix it, nor does any amount of fiddling with anything; only resetting the router fixes it for 30 minutes (resetting the cable-modem doesn't work either)if I keep pressing the standby button on the cablemodem after browsing some pages, the connection works indefinitely (If I press the button to restore the connection, browse some pages, press the button again to cut the connection, it works fine for hours and hours without issue. Only when I leave it active for a while does it finally stop. I repeated this for three days with the same results.)I tried cleaning the pins in the router’s plugs, but that didn’t work, which was not really a surprise since I was not getting a lost connection error.

Obviously my first thought was that the router was having a problem, and this is borne out by some tests. The problem is that when it drops, it is not a full drop since I can still do things like ftp ftp.mcafee.com and such which means that the connection and DNS are still working. Moreover, if it were the router, then why does it stay alive indefinitely when not connected to the cable-modem (i.e., no outside influence)?

The problem doesn't seem to be either the cable-modem nor the router, but rather an interaction between the two, like something from the outside (port scan? hacker? ISP?) that is triggering a problem in the router. I see that there have been a couple of vulnerabilities for the DI-524, but those were a while back and should be fixed since I have the last firmware for it.

I don’t think it’s my ISP (Rogers) since I have been using the router for several years without problem and can connect indefinitely when bypassing it. But I can’t rule them out since that is one of the only possible things that could have suddenly changed.

(I note that when I opened the router, I heard a very high-pitched noise from somewhere near the capacitors/ferrite ring which I don’t think I heard the last time I opened it a few years ago, but then if it were that, then why would it affect only a very small, specific set of functions?)

Update:Last week, my Internet connection dropped out for two days. I called the ISP and they had me bring the cable-modem in to be replaced. I exchanged the SB5100 for a new cable-modem that has a built-in router with wireless AP and firewall. (I left it in gateway mode instead of bridge mode.)This morning it started behaving just like the old router. Most protocols continued to work (mail, P2P, NTP, etc.) but web-browsing (HTTP) was dead; I could not even connect to the cable-router’s web-interface. I rebooted the cable-router and HTTP functionality was restored; exactly like the previous router.

I find it highly unlikely that this could be a coincidence or related to the router itself since the new one is literally brand-spanking-new (bagged, twist-ties, in a box, with that new-plastic smell, etc.), and completely different from the old one (the new one is an ISP-branded model labeled “Hitron” while the old one was a D-Link DI-524).

TP-Link 300Mbps Wireless :: WR941ND Internet Connection Loss

Jan 14, 2013

Region : UnitedStates
Model : TL-WR941ND
Hardware Version : V3
Firmware Version : 3.13.9 Build 120201 Rel.54965n
ISP : TDS

Currently I am using 2 WA5210Gs and a WR941ND to send my wireless connection from one home to another. The original home utilizes a TDS DSL modem/router combo. Everything works great, but then generally withing 24 hours I will randomly drop my internet connection in the second home, but the network is still up and running strong. The modem is not the problem, because I am able to grab a faint signal from the WA5210G AP connected to the modem and access the internet, and the client WA5210G AP is running at full signal. If I power down the router and restart it, the problem is fixed, but happens again within 24 hours. Originally I changed the IP on the WR941 thinking it was an IP conflict with the modem/router, but the problem occurred again. I also tried switching to unicast DHCP, but the problem still persisted. I looked for a firmware update, but couldn't find a newer version..

Linksys Wireless Router :: E1200 Frequent Loss Of Connection

Feb 3, 2013

Having several issues w my E1200. For quite some time I have had intermittent loss of internet connection. This was somewhat true even before I got a wifi router. & it has continued. Recently it has been even worse & I'm not sure if it is my isp, my cable modem or the router. ISP came out & checked & said signals looked ok, although modem is old.Now i find out that the version of Cisco Connect that i had been using is incompatible w Mountain Lion so it won't work now. & newly downloaded dmg files say they are damaged (or that app has been modified or damaged--I'm not in a position to tell which but same results after I downloaded a 2nd time).
 
I have been having more frequent loss of internet connection at home. & when I click on the wifi icon to check, it shows it looking for networks. Also it has not been uncommon to see that it has switched to my guest network.Why would it switch to my guest network? What is the difference between the 2 besides the fact that I guess the guest network doesn't have access to everything on my regular network (which right now is only my iPhone, but may get wireless printer).Also when it shows the lists of networks that it "sees" my guest network does not show a padlock icon so what does that mean? It does have the default password.
 
Also because I had no idea that Cisco Connect was not compatible w Mountain Lion I didn't even think to check for upgrades before I upgraded to Mountain Lion & now I can't open Cisco Connect. Shows unsupoprted OS. & I'm also stalled trying to update the firmware for the router.I'm really beginning to see why it was cheaper than an Apple Airport Express. Even at a very low hourly rate, the lost time spent when this has not been working right has not been worth what I saved on the purchase price.
