Hi I've got a problem. I use a Zyxel W-LAN USB client to connect to the wireless network. The problem is that i wanna use TKIP for the connection. But the default setting is AES. If I change this setting in the Wireless Settings (Where also can be set the PSK) to TKIP, it just will work till I restart my computer. When the PC restarted, I will have AES again. Why is it like that? Is it a bug? Thanks for answers.

What drivers are you using for the ZyXEL USB adapter? I suggest uninstalling them then reinstalling them in either a Vista compatibility or XP compatibility mode depending on the driver version. You can do that by right clicking on the driver file and going to Properties > Compatibility tab. Once you change to either Vista or XP compatibility rerun the driver installation.MS-MVP Windows Desktop Experience, "When all else fails, read the instructions"
