The office that I work in has a secured wireless network. I have connected five different PC's to this wireless network. The OS's on these PC's include Windows XP, Windows Vista, and Windows 7. They all detect the wireless network automatically. When I try to connect to the network, I am asked for the Security passphrase. After I enter the passphrase, it works - I am on the Internet. When I check "Properties" for the wireless network after the connection has been established, the security method is listed as "WPA-Personal" and the encryption type is listed as "AES".
I am having a little trouble with just one of these PC's. It is able to connect to the Internet, and I have checked for it to connect automatically. It does connect automatically, but several times a day, it seems to disconnect. Normally this happens when I return to the PC after being away from it for a while. At these times, I am unable to get on the internet. When I look at the connection icon on the System Tray in the lower right hand corner of the screen, it says "Acquiring network address".
It seems to me like maybe some power saving feature is turning off the wireless adaptor after a period of inactivity, but the only power saving function I am using is to turn off the monitor after fifteen minutes. In Device Manager 'Properties' for the wireless card, I have the power saving mode set to 'CAM (Constantly Awake).'
If anyone has any ideas or can tell me anything else I can check, I would really appreciate it.
