Frequent reset of router!!

post #1 of 9
Thread Starter 
Hi, I have a LinkSys router (forget the model) connected to a Comcast Modem. I have been using it for the past 3-4 yrs without any issues.

I recently upgraded my laptop to Win7 and started noticing frequent "Unidentified Network" issues. Typically this happens every 3-4 hrs and I lose my internet connectivity. I have to then disconnect / shutdown my wifi connection and reconnect from the laptop. I dont have to touch my router!

Any ideas what is happening and how can I resolve this? I never had this issue on a XP hence guessing the combination of the router firmware and Win 7 conflicts?

Thanks!

Most likely the laptop wireless controller, but possibly the router as well.

Go to the start menu and type 'Network connections' in the search bar at the bottom. Under 'unidentified network' it will say the manufacturer of the wireless adapter, such as broadcom, intel, or realtek. I had a Realtek RTL8187B that I had to replace because of a similar issue.

Once you find out what the manufacturer and model of the wireless controller, go to their website and download the latest drivers for it. Kind of a longshot but basically whats happening is that something is causing the communication between the wireless controller and router to fail and its most likely the wireless controller hardware or the software drivers for it.

Do you have any other devices that use the wireless connection at all?

Thanks Malisk! Will try updating this. I have a Dell Wireless 1397WLan minicard from Broadcom. I have another Win7 laptop from Lenovo that is facing similar issues. My iPhones connect to the same network but they never seem to have any issues.

What is surprising to me though is that this happens only in my home network but not at my workplace

just update your Wireless card driver..
In worst case just buy a new/faster wi fi controller card (easy to replace) for 30 box on ebay
edit: nope, it's not a driver problem but the router may be unable to handle communications on ip v6 ..

Ya, wireless hardware/connections are pretty frustrating. There's never a sure thing as far as suggestions for this problem. The router could be mishandling the communication as well, causing your wireless card to stop communicating.

If it is a pretty old router you may want to upgrade anyway. Wireless routers have come a long way in the last 4-5 years so it may be incompatible in same way with the new wireless adapter in the new laptop.

Take it apart, remove the board and bake it in the oven at 325 for 10 minuets. It works for graphic cards, maybe it will help routers too.

If the problems started when you upgraded to Windows 7, it's likely a problem caused by a driver in Windows 7.

For what it's worth, solder joints going bad in routers isn't a common problem like it is in GPUs, so baking the router probably wouldn't help with too much ...

Before baking it or buying a new one ...

Try updating the drivers on the wireless card. My experience with Dell wireless cards - specifically the 1397 and 1510 is they are junk. I'm not sure if it is Dell providing crappy drivers or Broadcom cards being bad. Every Dell laptop I've had got the Broadcom card replaced with an Intel 3945 or 4965 card. That IMMEDIATELY solved ANY issues with wireless dropping.

The "unidentified network" thing is popping up when you disconnect from the network because it's a feature of Windows Vista/7 ... it is, in a way, asking you to tell it if the wireless network you are connected to is a "home", "work", or "public" network. Once you label it as such you should be OKAY.

Lastly, try updating the firmware on the router. If you don't feel like doing something major like DDWRT or Tomato, just get the newest version from the manufacturer.
