Recently I built a new gaming rig, and decided to give it wireless connectivity so I can have the computer sitting on a cooler area of my house. Now, I found I get lucky if I can even get a wireless connection on it, because I often have a lot of trouble getting the wireless to connect, usually Windows will say that the settings for the network saved on the computer don't match that of the actual network. I checked my laptop running Windows 7, and it connects fine there. The method of security is WPA-PSK and encryption is TKIP (seems to be only available form of encryption in router config). The laptop is configured with WPA-Personal and TKIP and is connecting fine. If I do the same with my new rig it refuses to connect still. If I try and reset everything ,then Windows will allow me connect, but when I try typing in the security key, it "is never correct". I have typed it countless times to make sure and Windows says it's "incorrect, please try again".I also tried updating the card drivers, to no avail.
Edit: I recently got connectivity again on the desktop after much trial and error. However, if I leave the computer idle long enough, the automatic sleep knocks out the connection . If I have my laptop in the same place as this newly-built computer, it connects fine with a strong signal. On the desktop Windows states that the network is "hidden" and that could be the problem, yet it shows up in the list of networks?
I've heard of a lot of wireless issues after Windows 8 upgrades. Woud've gone with Windows 7 until 8 has "matured" (i.e., had all serious bugs fixed), but my local computer shop was out of Windows 7 stock. Hope this won't be the new Vista all over again, don't get me wrong, I have no issues with the new Start screen or anything UI-releated, I just hope I didn't spend $150 on potentially unstable software... me'thinks a Windows 8 service pack won't be around for another 1-2 years to fix this if it's a bug of some sort.
