I have a PC running 32bit Windows 7 Professional. My wireless internet card is Edimax EW-7128G, it is inside my computer case and it is connected to an antenna.

My problem is: I have a wireless connection to my router, the signal is fine and it's not slow or anything, but it just keeps disconnecting every 30 seconds or so, then connects back, then it disconnects, then connects back and so on.

This is new - it only started about a week ago, everything worked just fine until then.

I know it's not a problem with the router because: Other computers can connect to it easily and they work just fine, no disconnections (My phone too).

I know it's not a problem with the computer or the wireless card itself because: I have Ubuntu installed side-by-side with my Windows, and when I switch to Ubuntu the internet works great.

This caused me to think it's probably a problem with the wireless card drivers installed on windows (Ubuntu auto-installed them, I installed them manually on windows): I tried uninstalling them, and then installing them back again, sadly that didn't help.

I'm kind of lost here - can anyone think of anything else I should try?

Thanks :)
