Networking & wireless: Help with intel wireless adapter

Help with intel wireless adapter

Hey. I'm having wireless problems and I've always had good luck with the cnet forums, so here goes. I have an internal wireless card which has always had spotty performance, usually much less than my other computers. Over the last couple of weeks though, the computer now boots and loses the signal and can no longer identify any signal (I live in range of ~25 wireless networks). When I try to connect manually, an "an unidentified problem has occurred". The only thing that will let it reconnect is if I reboot, and then it cuts out after a few more minutes. I downloaded new drivers for it from the Dell website, and that made it work initially, however it then lost the signal again. If I go into device manager and roll back to the previous drivers, same thing, ten minutesish of working. Then I revert to the newer set and it happens again. I just downloaded an even newer set of drivers from intel's website, 12.2.0.0, and the same problem occurs. All this is leading me to believe that there is a hardware problem, but if anyone knows and easy way to check, with some kind of diagnostic program for instance, then fire away. I looked at the ultimate boot cd, nothing there for wireless adapters, and a googling didn't return anything especially promising. Any other ideas or help or anything at all would be much appreciated. Thanks

I have a dell inspiron 1525 running vista home premium (32 bit). It has an intel wireless wifi 4965 AGN. The current drivers are the 12.2.0.0 that I mentioned.
