Intel Prowireless 3945 a/b/g

Basicly, this is what happends. I am on the internet and everything is fine. Without warning, the radio will turn itself off and the wireless connection will be disabled. I can not get into network connection to re-enable it. There is no error message. As far as the AP, honestly, I do not know. I am using a university netowrk. And yes, the wireless really does disbale itself. I have also ran virus and spyware scanners with nothing out of the ordinary. In the device manager everything is OK. No yellow question marks, and no red x's.

Well, I started with Windows and then moved to ProSet. In all honesty, it seems to happen less when using ProSet. With windows, I was restarting the computer about 3 or 4 times every hour. With ProSet, about once or twice every 4 hours (restarting is the only way to get the wireless on again - network connections seems to lock up when the issue happens).

Thanks for your help with this...

I have used both the Intel and the Dell drivers already.

The radio turns itself off. The "wifi" light turns off. When I go into "My network connections", if it lets me in, it will say that it is connected. If I try to right click it, nothing will happen and "my netowrk connections" will lock up. If it does not let me into "my netowrk connections", my network places just locks up as well. Now, after a restart, ProSet will give me a nice prompt that says your netowrk adapter has been disabled.

It happens randomly, and I never tried not associating to an AP. I will try that, and in safe mode.

That is pretty much all of the info. If I went for a swap out, would they replace the unit or just the wireless card?

It happens randomly. It will happen when the laptop is sitting and idling, and it will happen when rendering a web page. It has never happened during a windows update. Windows is up to date.
