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?

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.

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.

I am having trouble with my wireless internet at home, i am using a dell inspirion with windows 7, and an ipad, my router is a Netgear DGN2000, what happens is that the connection is intermittent on all the devices when using the wireless connection but no problem when using a direct connection.
These are the spec when it is working:

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??

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.

I am running an 877W in the home that for the most part works fine, however after being connected for a variable amount of time I partially loose my DSL connection. Line sync stays up, but the traffic is lost.
A shut/no sut of the atm or dialer interfaces does not resolve the issue, only a reload or power down/up will fix the prob short term till it happens again.
Am currently running advipservicesk9-mz.151-3.T1, but have also rolled back to advipservicesk9-mz.124-24.T5 which has the same issue. Have tried a 857W with the same results. So ruling out IOS and hardware, its pointing to a config issue. It has also only been an issue since changing from ADSL1 to ADSL2+.
interface ATM0
no ip address
no shutdown
no atm ilmi-keepalive
exit
[code]....
I've tries some changes mentioned here and from other sites, but no success yet...

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.

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.

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.

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.

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?

Im currently experiencing an intermittent connection on my office and we just upgraded from 4Mbps to 10Mbps. Latency is high when pinging commercial website like yahoo.com,it shoots up to 200sec. ISP router is connected to two HP Procurve Switch, then the workstation and servers. Already did a router/modem test and it failed, I advise our ISP to change the router but it were still experiencing the same problem. Network drop is also experience even after office hours, eventhough only few workstations are working.

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.

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.

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.

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:

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.

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.

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.

Bought an E4200 to replace my Netwgear router and am experiencing the following problem.One of my wireless boxes serves as mu mail server. I've been running this configuration for years so the only thing that has changed is the router.The neworkd is up and all wireless clients can connect, but after some time, access to the mail server just 'freezes'. I say freezes as the nework icon (i'm using ubuntu' still show a connection. In addtion, there are not error in any of the logs. I just seems that the mail server and the router just stopped communication.

I have a Cisco 1242 AG wireless access point with the goal of having multiple SSIDs. I set up one network which broadcasts correctly but only sometimes can I connect to it.
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.

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.

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.

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.

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]
