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).
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..
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 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 playing the online game League of legends i suddenly lost internet connection. when loading pages some will not connect and I'll get a message saying I'm not connected and should try reloading, refreshing the page usually fixes the problem, occasionally multiple refreshes are necessary. I've never had this problem before and it's rather inconvenient for me as I need internet access for university.
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

I was wondering if it is possible to share my internet connection to specific computers on my home network. Both my laptop and desktop computer is connected to the same Wi-Fi router (no internet connection). This network connection is mainly used for file sharing. I want to share the mobile internet connection on my laptop with my pc without giving the other computers on my network access to the internet connection and without disconnecting from the home Wi-Fi router. Is this possible and if so how
How to block Internet Connection during specific time.for example i want to block everyday between 8am to 12nn, then 1pm to 5pm.what are the options and better to achieve this kind of policy??
I am facing a proble in wireless connection speed that is getting very slow at a specific time, i.e., from 12pm to 2pm and from 9 pm to 2 am. The service is unlimitted type contract
am not a network expert but I understand that the download speed is always higher than the upload speed, right? I just bought a new internet package that comes with 5 mb/s download speed. The Upload speed should be around 1 mb/s right? Speedtest.net gives me 5 mb/s download speed and 53.62 mb/s upload speed. I called my internet provider and the girl told me it is normal. How can that be normal? I also have another weird issue. When I try to watch a video (youtube, netflix, etc...) the video starts loading correctly but stops loading after 10-15 seconds. I did a download test by downloading Itunes and the download starts correctly at 600 KB/s but after a 2-6 seconds, the downloaded megabytes stop increasing and download speed just drops until it reaches 0 and the download cancels itself.
Just installed 2 E4200v2's for a customer today. Was very optimistic because they worked great in my lab, both for my Win7 laptop a MacBook. And after installing 1 on-site and testing w/ my laptop, it worked fine.BUT problems arose when I installed both at the same time (I don't think I ever did this in the lab) and then I tested some computers. Every computer that I tested (except mine of course), cannot authenticate correctly using the WPA2 password.
For the Mac's they get the error "The wi-fi network... requires a WPA2 password" then after entering the *correct* pswd, it says "Invalid password". They're a Mac shop, but I did try one other Win laptop and that also had a problem, and the error was something like "security mismatch" although I was rushed and didn't write it down.
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]
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.
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)
Intermittent loss of connectivity in two level router network.Static ip address from DSL modem into WAN port of linksys wrt4g, LAN port to WAN port of dlink dir-615. All pcs, printers ans a NAS connected to the lan side of dir-615 using 16 port splitter box. Wifi set up on both routers. Router 1 is 'public' to the building, router 2 is private to the non profit org. Inermittent(1 or 2 times a week) loss of connectivity to the network and to internet.
I have lately been having trouble with the speed of my wireless connection. usually downloads can run at approx max 1.2MB/S i have noticed significant speed drops in my downloads - when i connect to the network it starts off at 130mpbs, but then quicky drops to 12mbps - no settings have been changed recently.

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?
My problem is that i have a packet loss of like 2% to 6%, which is a lot considering that i play a lot of Online games, causing lag spikes and net frozes.I will say all the information i can about my pc.My PC hardware hasn't been modified, so the manufactor page ( ) tells what is installed in my pc.About software, i need to find if this problem is software-based, my AV is Microsoft Security Essentials and i use MalwareBytes too.About how im connected, im connected via Wireless to a router. (dunno model, i just know its a encore router)
I have two routers, Cisco 3825 and 2811 connected via a p2p ethernet link. The two sides of the links have Huawei muxes with 100/ full duplex set on their interface. I am facing almost 40% packet loss but the supplier is unable to identify any issues at their end. We have tried setting different combinations of duplex and speed settings but no improvement. When set to auto/auto the interfaces are negotiating to half duplex and I am sure this is the cause of the packet loss. Also I heard of auto-negotiation on MUX ports but supplier confirmed no such settings but only 100 Full duplex. If the router iterface is negotiating to half duplex so I suppose there is some thing with the negotition problem with MUX and router port ?
On C3825 I have a Gig interface whileas C2811 has fastEthernet. I guess Gig interface should not negotiate ? Is there a way to pin point the exact fault to supplier ? Also is there work around for this?
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?
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.
I just bought a "DLink Xtreme N Gigabit Router DIR-655" I configured it correctly. It works well for the wireless connection but my Lan connection (wired connection) does not work. The Lan computer connects to the router but cannot access the internet. All of my machines work OK with a Netgear G router, including the Lan computer.
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.
I just recently purchased a Cisco ASA 5505 ASA ver 8.2. I run a teamspeak server/ssh/dns and domain on the same server on the network. Before I switched to the asa, I have a regular DGL-4100 that ran with no issues. I have noticed that the connections are very unstable and disconnect frequently and when they do they take 1 to 5 minutes to be able to reconnect. I have done some cisco IOS but am fairly new to this. [code]
I recently updated my NVIDIA nForce 10/100/1000 mbps ethernet driver and now my computer wont connect to the internet. In fact, it doesnt even acknowledge that the ethernet chord is plugged in. I am running windows 7 and have had no problems for years now. Since ive had my PC for so long I decided it was time to update, now im at a loss of what to do. I am currently using my laptop to submit this post, as my PC is not a wifi enabled device. I recall having this problem back when I first had this computer made and found a resolution online, (cant seem to find the same site i used back then.) I recall that it had something to do with me using the command prompt. While i have been looking for an answer, I have tried the following with no avail:
Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log press enter Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log press enter Reset WINSOCK entries to installation defaults: netsh winsock reset catalog press enter
Is it normal to have packet losses of between 2 and 6% when using wireless. Laptop is running Vista Home premium. Internet is DSL light Router is Netgear WNR834B. Signal strength is good
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??
As I continue to have various issues with my revision A version of the DIR-825, does an updated firmware is in the works? Or has revision A been DE-supported by Dlink?
I'm still having issues with: Share port printer no longer being recognized/usable until router rebootedLoss/overload of router which causes all clients (wired and wireless) to loss connectivity Router rebooting itself periodically
I've tried all sorts of settings, and I'm still holding out that its a setting possibly, but I have a E3500 and devices on both 5Ghz and 2.4Ghz... Most of them, probably when idle, seem to stop working over WIfi. They still have decent connection, but every internet related request just times out. Disable and reinable the wifi and it works great again.
Could this be defective wifi radios? or could it really be interference? I have it happening on multiple devices. Also, I'm not far away from the router when it occurs, and when I reconnect, it seems to work just fine for a while. Basically the big problem is on the cell phones and tablets because I'll miss notifications... I'll turn off the wifi and turn it back on when I use the device next, then a flood of notifications will come in. Again, it's not just a phone thing, tablets and laptops have the same problem, that's just the main reason I want it fixed.
I have been spending days !!! trying to resolve why my laptop pc disconnects frequently from its wireless connection. No discernable pattern to disconnects, totally random. Happens in cycles of disconnect/auto reconnect or will go hours of stable operation. What I have noticed is tht the connection speed seems to vary, from a hig of 54.0 Mbps to as low as 2.0 Nbps. At same time the desktop pc (hard wired to modem) stays connected at 100 Mbps.Using RCA modem, WRT160n v3 router.
I hope this question has not been asked here in the past, as I have googled for answers many times..I live in UAE and the ISP here blocks many sites and services which made me do the following:I have a notebook PC running WindowsXP with two connections to the internet.LAN connected to my ISP which is 30mb/sWLAN connected to the internet through DD-WRT router running OpenVPN and the speed is not that fast.hat I do now is that I have to disable my LAN and access the internet through WLAN (VPN) and have to enable LAN again whenever I need to download large files
I can't access the following a specific website from any computer in my house. I am able to access all other sites. I have tried Firefox, IE, Chrome. All i get is the following error: "The connection has timed out" I called my ISP this morning, and they asked me to try adding a proxy server in IE. That is, Internet Options > Connections > LAN settings > Proxy server > proxy.tpg.com.au:3128, After doing this i was able to access the site! What could this mean?
