WNDR3700 Internet Stops Working
May 2, 2011
After buying a new WNDR370. Sporadically and seemingly without any cause my internet will stop working. Diagnostic will always report it as "DNS Server is not responding." I've also discovered that if I enter my router settings and even just switch the DNS settings from Auto to manual or vice versa the problem corrects itself instantly-then next time it happens I just need to do it again.
I've already tried resetting my entire network and rebuilding the recommended way. Modem, Router, then computers-connecting each only after the prior has finished initializing. Hasn't worked though.
Currently I have my main rig connected directly to the modem to try and find out if I experience the problem at all this way, this is a pain in the ass though, and I don't know when long enough is long enough as the issue is completely random and simply just may not happen.

It's fairly hard to explain what happens but basically, say I'm playing some type of online game, all of a sudden anything server sided such as HP amounts, damage amounts, etc. just disappears but the animation runs fine such as attacking being hit, etc. All of a sudden it'll jump forwards and I'll take any damage and do any damage that had been happening until the issue started. This happens constantly and it's really frustrating but on top of that my internet will slow to a crawl..Say I'm trying to send a message on Skype, it won't send for the longest time and I won't be able to recieve any or even open a new webpage until the problem fixes itself.'ve looked around a bit and thought I fixed the issue, I'm on wifi and multiple devices are connected but not always in use, and the forum I found suggested an ip conflict and said to open up command prompt release the ip with ipconfig /release and then renew it with ipconfig /renew.

My computer runs bit torrent almost all the time, sometimes when I start Firefox the home page google never loads and neither do any other web pages yet bit torrent is still working as if nothing has changed. If I start a download in Firefox come back to the pc a few hours later Google doesn't load but the Firefox download still continues.What causes this is it DNS ?

My internet (wired and wireless) usually works fine, but occasionally (read: every few days to weeks) the connection will suddenly black out for a period of time, anywhere from an hour to a day. I have tried resetting both my router and modem, and going through all the settings on my laptop, but I'm pretty sure it's not my computer, as no other devices can connect either. During the blackouts, when I look at the modem, the internet light will turn on for a second, then go off and then the red "alarm" light (aka "something is wrong" light) starts blinking like crazy, and this keeps repeating. This resolves itself after anywhere from a few hours to a whole day and everything is normal again. The light show, and the fact that I can't find any other problems, leads me to believe that it could be a problem with my provider (or the network itself) and not a hardware or software problem, but I can't be sure of this.Also, during the blackouts, I can connect to the network, but it shows that limited connectivity symbol (exclamation mark thing) and says no internet.

So here's my setup:Computer A is connected directly to a cable modem box via USB. Computer B (which is sometimes a laptop and sometimes a desktop) is connected to Computer A and shares its internet connection via Ethernet because I am too cheap to buy a router.A few days ago we borrowed a Belkin wireless router so we could have both desktops, the laptop, and my fiance's iPod Touch access the internet at the same time. That worked fine but once we returned the router and tried to put everything back to normal, it didn't work. The only computer able to access the internet is Computer A (or whichever one is directly connected).I tried resetting the modem and restarting both machines. I tried disabling all of the connections that showed up from using the router.Windows states that the IP isn't properly configured or something of that nature. I tried setting it to automatically set the IP but to no avail.Here is the part that really confuses me - I can access Computer B from Computer A via LAN using the ethernet cable, so the connection between the two computers is fine.

I have a windows vista pc networked to a second pc. I have wirelessly networked internet to 2 laptops. I have an actiontec wireless modem by verizon. All of a sudden my host pc started randomly losing internet connection, but the wireless laptops still have a signal. It seems like the host sometimes can't "see" the modem.Here are my settings while the internet is functioning.Microsoft Windows [Version 6.0.6001]Copyright (c) 2006 Microsoft Corporation.

I bought this router and ever since my internet connection will drop out for 5 minutes at a time then come back in. This happens on both wifi and the wired connection. The weird part about it is that if there is a program that maintains a constant connection, e.g. xbox live or an online MMO, they don't lose connection when every other device or even tabs within the same browser all lose connection.
BTW It's the REV_B with the 2.07 firmware.

I can no longer browse through any browser, or update any programs (even though I am still connected to my wireless router). I have already done a Refresh, but the problem persists

Wireless internet connection stops working after anywhere from 10 minutes to two hours, a message pops up telling me it is "impossible to connect to my preferred wireless network", and then it fails to detect any wireless connections at all. The strangest thing is that when I try to "repair" the connection, which used to work, the computer immediately shuts down and restarts itself. It also seems like when I attempt to download something, like a movie for example, the connection fails right away, while if I'm just surfing the web it usually lasts around an hour before stopping. And when I restart the computer again it works perfectly fine at first, like right now, but eventually does the same thing.

I boot up my computer. I close it over. come back later. open it. Computer will connect but with the small yellow triangle. Thing is though, it's only my computer that ever has issues with my internet connection. My sisters laptop has never had an issue with out internet. Yet my laptop is able to connect to the neighbors internet fine. The solution to my problem almost all of the time is to simply reboot my computer, which solves the problem(most of the time). But i'm getting so sick of having to do it. The other times when a reboot doesn't work I have to manually reset the internet. As i'm typing this I'm on my neighbors internet. my sister is connected fine to our internet but my laptop simply won't work with it so i'll have to reset it when i'm finished this Some useful information might be that this problem only started happening ever since my computer got wiped.I've tried updating the drivers but apparently they're up to date.

I recently bought a new laptop (Asus U47VC) and i am having internet connection issues. When I am at my mother's place or at school, I have no problem connecting to the internet wirelessly. However, at my father's place, my internet stops working every couple hours and will be unable to connect to the network until i reset the router and modem. Once the reset is complete, I am good for another couple hours. All the other devices ( laptops, iphones, etc.) do not have this problem and the connection is never an issue. I have read that this could possibly be a problem regarding IP addresses but I do not quite understand how to fix this.

I just bought a new netgear n600 now it seems all my devises are slower. 2 Xbox 360s 2 laptops. 1 pc also on my dell d610 now when i try to watch any video the internet stops working. we use google chrome. I am pretty sure its the router. we use mediacom for internet and get at least 20 mbs. oh and the slowest xbox is run with a ethernet cable so its not a wifi issue with that one.

Basically, my internet's been fine until about a week ago. I'm currently using the Aztech DSL1000EW router/modem which has been working great up to now. My problem is this: after about 5-30 minutes (time fluctuates, annoying because after 15 minutes of continuous usage you think the problem's solved!) all webpages suddenly become 'unavailable'. I've disabled proxies under LAN settings, tried flushing DNS, resetting winsock with the netsh commands but to no avail. To get the internet to work again, I can just go to my router page, click disconnect and reconnect and it'll work for another 5-30 minutes.

I had to move to a remote area in which I can only use a 3G mobile internet connection. The 3G connection is working fine, that is until I plug in my Asus RT-N12 router in order to create a wireless home network between our computers (for file and printer sharing).
For me it seems like firefox is trying to connect to internet trough the router. But that is not possible, since the router has no internet. The only internet is from the 3G mobile internet stick.
How can I tell firefox, that it should look for internet in the 3G connection instead of the router?

We use our internet to watch Netflix. We have had no problems until recently, I called the satellite Internet company(which is a local co.) they told me my router was going out. I bought a new one, problem solved! Right?!? WRONG my husband told me my neighbor just got Internet and has been playing Xbox everyday which coincidently is between the 5:30pm to 10ish pm we have been having issues with our router. What can we do to fix this? Do I have to buy a bigger router? He is not stealing off mine because it is password protected that was changed when new router was setup and programmed. I have been running of a Cisco Linksys E2500 advanced dual band n router. The router is in the same room as the TV accessing it, which we previously had no issue connecting anywhere in the house or garage.

I'm having a bit of trouble with my e4200, It keeps on "dropping" connection, and by dropping I mean it constantly around 3-5 minutes the internet stops working with all my computers, it's connected by wifi with 2 PC's, and 1 PC is wired with an ethernet cable, and I also have 2 mobile devices connected at it. The internet would start working again within 30s, to 1m, but that it drops soon.Methods I've done to fix it:
-Updated firmware to the latest one
-Set the MTU to 1400
-Reset it, (30 second press)
-Rebooted, (Cooled down, doesn't really run hot just a little warm)
-Restored to factore defaults

Setting up a netgear n600 (WNDR3700) in my home. I have tried connecting two PCs to the LAN and am only getting 100mb/s with most of my patch cables(all are cat5e). I was only able to achieve 1Gb/s with 1 of my cables(which is actually a few feet to short for my shortest run). Both PCs have gigabit capability. What are the chances that 5 out of 6 cat5e cables are bad? Am I missing something?

My old router (a dlink dir-615) works just fine, but I figured I would upgrade and try to run OpenWRT or DD-WRT so that I could have one VPN for all my devices.
Anyway, I took the router out and followed the instructions (power off modem for at least 1 minute, connect modem to router, router to computer via ethernet, turn on modem first, wait for it to fully boot up, turn on router, wait for it to fully boot up, and then run the setup on routerlogin.net. The router is currently setup and I can connect my computer or iphone to it just fine, but I cannot access the internet. It doesn't make a difference whether I'm connected via ethernet or wifi. Either way, I get a "No Internet Access" message from Windows 7.
I've tried turning everything off and starting again. No luck. When I go back to my dlink router, everything works fine again.
So, in short:
Modem + ethernet = internet
Modem + Netgear router + ethernet = no internet
Modem + Netgear router + wifi = no internet
Modem + Dlink router (wifi...haven't tried ethernet) = internet

I have a Asus n55s. The wireless acts very funky. It sometimes disconnects and stops working. Sometimes, it will stop detecting any nearby wireless networks altogether. Then I have to enable and disable the wireless functionality until it starts seeing nearby wireless networks.

I've been having this problem with my laptop's wifi for a while now and it's been getting a little out of hand lately that I can't deal with it anymore. I asked some friends and they seem to have the same problem too but not nearly as often as I do. Every so often, my laptop's wifi just stops working so I turn it off and then turn it back on and it starts working again. My friend says it happens very rarely to him but for me just today it happened 2 times within 10 minutes

I'm having is that every few hours my TCP/IP protocol stops working. The modem lights remain normal but I can't connect to anything. The only thing that works on the internet is traceroutes at the command prompt which function normally. The solution is that I have to reboot and then everything returns to normal until a few hours later when it happens again. There are no error messages on any of my browsers. The page just goes white immediately. When I try to retrieve my email, I get a message about the TCP/IP isn't working.

On Windows XP, my integrated NIC stops working after hosting a server. The server starts fine, ports are forwarded, firewall is down, modem is fine, but when I receive a connection, it shows they have made a connection, but then they drop, as do I. I can't browse or ping anywhere. I have to physically disconnect, then reconnect the ethernet cable to the port, or restart the computer. Upon ipconfig, the adapter is set with the Windows default ip (169.x.x.x) and cannot be /release'd or /renew'd.

Once every couple of days the wireless service seems to disappear. I've connected to the router from a wired computer and everything looks ok from the d-link panel, however its not showing up as an available wireless network on the wireless units. Pulling the power off for 30 seconds tends to get it working again. I'm configured bg and n. I need a mix... an old B laptop, have one machine that has a G NIC, and the rest are N.

I have a cisco asa 5010 where, during the process of configuring, the outside ports become down/down. The /0 port won't even reactivate after cycling power on the unit.Port /1 is the inside interface and it is not affected by the problems.I switched the outside port to port /3 and it worked for awhile then it stopped working. I switched it to Port /2 and the same thing.Port /2 and Port /3 are on after a power recycle but shut down completely (down/down) during the reconfiguration. It seems like a hardware failure, but I'm wondering if it could be anything else.

I recently setup a site to site vpn between a asa 5510 and router 1921. It was working great all night and this morning. When traffic stopped rolling through for a few hours the tunnel shutdown. I checked the router using cisco configuration and tells me the tunnel is up. When I check the asa it does not show up in the active tunnels. Any know what would cuase it to drop? and if so what can I do to avoid it.

I have a problem with a wireless adaptor on a Toshiba Tecra (A11-1EE - PTSE0E-065052EN) running Windows 7.The wireless adaptor works fine but every now and again it will just stop working. The operating system says that the adaptor is turned off but it isn't. I've checked the driver but it is up to date.I have to disable the driver and then enable it again and then the adaptor begins to work correctly again.

I have a Comcast Motorola Surfboard rental modem. It works fine, great speeds etc etc. It has no router or bridge support.
I use this modem to connect to the web on my ps3 and PC. What I have been doing is simply unplugging the ethernet cord from one device, and putting it in the other device to switch. But of course things can't be simple...
Every time I switch devices, the modem tries to reconnect and does a cycle where every time it only reaches the "Send" light. So I have to power cycle my modem and wait about a half hour before my connection resumes...
I read something about PPPoE, but Comcast doesn't even use it so that won't work.
