Wireless Problem =\

I installed windows 7 64 bit on my father's computer. Everything was working fine except for the wireless adapter. Windows 7 didn't have a driver for it, so I had to search high and low for one that worked. Finally I was able to find an adapter for his Buffalo WLI-U2-KG125S that worked on w7. I installed the drivers and everything worked... for a while. Then my father started to complain that his internet was always down. I looked at the icon that shows the connection status and it would have a little yellow dot ontop of the signal strength. I would try to access the internet, but it wouldn't work. When I hover the mouse over the wireless icon on the status bar, it indicates that it is not connected, but connections are available. When I double click on the status icon, I can see the network I want to connect to. When I double click on the network it acts like it's going to connect, but then it doesn't. It will ask me for the network password, and then it tells me windows was unable to connect to my network. While all this is happening, the yellow dot has now turned into a blue rotating circle ontop of the network status bar. Ipconfig says the media is disconnected. Then, quite randomly, I see a yellow exclamation mark on the wireless status. It says im connected to the network, but not the internet. I wait a few seconds and it now works. Weird... I start surfing the net, 20 minutes later, it happens again. The connection drops. My wireless adapter seems to see the network ok, but it can not connect to it for some unknown reason. This is very strange to me. I myself run w7 on a laptop with an onboard wireless card and I have never had any conectivity issues. Any help with this matter would be greatly appriciated. I do not have any cordless phones in the house, and the microwave is too far away to interfere with the wireless network. It only seems to be happening with my father's PC; no one else has had any issues with this. I thought it was the drivers at first, but it still happens even with a new network adapter I bought.

Oh yeah and sometimes the internet connection will be so slow that the browser times out. Yet... on my laptop, everything works fine. This leaves me to believe the issue is with the computer and not the wireless adapters. I just need to know what the problem is exactly so I can fix it and get my father off my back lol

Hmmm, I have the exact same problem, although I have a DSL router connected with an ISDN modem because I have two telephone lines, and I use a wireless adapter to connect to the router.
I never heard of microwaves interfering with wireless signals, is that true?

Hi djhaf,

Wireless dropouts are unpleasantly difficult to troubleshoot, no doubt that's why you are here.

At least one other thread posted a similar problem where the solution was a hardware replace (a different adapter though).

However lets Brainstorm and check the basics first.

• Could you please clarify if I understand this correctly, there is more than one PC connected to the wireless access point and only the Win7 PC drops out intermittently?

• 
  There are no error messages on screen; just loss of connectivity?

Questions

• A quick check of the Buffalo website shows no drivers for Win7, I guess you have already tried the Vista drivers?

• Are there any events posted in the event viewer that can help us?

• Have you tried changing to a different wireless channel? - There may be some interference that only this computer is picking up since Win7 was installed.

• How is the ipaddress issued? Dynamic/Static? Modem/Server? Is this the same for all PC's on the network (if there is more than one)? - This may help us pinpoint what's causing the issue.

• Are there any scheduled jobs or automatic updates running at the time of connectivity loss?

• Is the wireless network still secure. i.e. no-one else knows the password and is connecting? - Try changing your password, and make it more than 8 characters long... or as long as you can.

• When connectivity is lost, can you see the point of failure. e.g. If you do a IPCONFIG /ALL from the CMD prompt you may notice that the Default gateway is missing.

• Are you using the windows default wireless software or Buffalo's Client Manager Utility?

EDIT - I have Win7 64bit connected via a Linksys WMP300N adapter to a Linksys WRT300N router - It works fine.

Good point!

I bought some linksys-cisco usb adapter. It gave me the same problems that I had with the buffalo adapter. I was able to fix my problem by updating the router with a firmware update. Thanks for all your help guys!
