Could this card be incompatible with this desktop's hardware? No, because when I booted up using Linux instead of Windows, it connected just fine, and I could access resources on the network. Besides, I was able to scan WiFi networks in Windows--just not connect to them. Could it be a problem with the access point? Same problem. Maybe the WiFi stack is messed-up in this Windows install? I happen to have two other non-Intel WiFi cards just sitting around orphans from hardware upgrades.
When I replaced the Intel with those other cards, I was able to connect just fine. Swapped the Intel card back in, and things die again. Maybe Windows 7 just doesn't like the Intel or maybe this particular My laptop also runs Windows 7 x64 and it also has an Intel WiFi card. Never had a problem before been using the on the laptop for a few years now. And just to make sure that it wasn't an issue with this specific card, I even swapped the desktop's the laptop's cards.
The laptop's tried-and-tested card, when put into the desktop, encountered the exact same problems, and the desktop's card, when put into the laptop, worked perfectly under Windows 7. I also have two other laptops that I manage that use the Intel under Windows 7 x64, and they never exhibited a problem like this. What about anti-virus? None are present on this system. Something is messed up with the Windows install? As a desperate I-am-out-of-ideas last attempt, I installed a fresh new copy of Windows 7 x64 SP1 on the hard drive's spare partition.
Still doesn't work. Any two of those components, when put together, works. Replace the desktop with another machine e. But all three of them together? It hates me. I just wished that Windows could be more specific about the nature of the failure.
Right now, the most that I can get when I view the diagnostic details is the report of an association failure caused by unspecified reasons. If you need to have WEP for some reason you will have these issues. Drivers are the other problem, but Intel provides those and it is best to use the Windows connection control unless you have Cisco security and AP's.
It may be due to a static IP address in place. This theoretically explains your "But all three of them together? Makes sense, right? I'll assist you further.
Hope it helps! A static IP was not set. Furthermore, the default is to use DHCP, and the card still failed to associate even with a fresh install. But all that is moot: The setting of a static IP or even the failure to obtain a DHCP address would not result in a failure to associate. Ok, try to delete the saved wireless connection in the Network and Sharing Center and recreate it. I suspect this has to be the root cause because there is some setting saved in the Windows PC that is causing this problem.
