Sigh... me again. Thanks again everyone for the replies.
Sometime earlier today my wireless abruptly stopped working. In both Vista and Kubuntu my WLAN is available and apparently running, but on both operating systems they fail to actually detect a wireless signal. My router is sitting ~4 inches from both this desktop and my laptop, and it works perfectly fine on this desktop... the laptop apparently is just not seeing the signal. As I understand it there is a wireless on/off switch in the front of the T400. I have toggled this on and off many times (the indicator light below the LCD goes on and off in Vista, but it does not light at all when I'm in Linux). I am at a loss. My wireless has worked perfectly since I received the computer and I am unable to determine why it would suddenly stop working.
In Vista in my Event Viewer it appears that I have two warnings regarding my WLAN-AutoConfig. One is of Event ID 4001 and says WLAN AutoConfig service has successfully stopped.
The other is of type 10002 and says WLAN Extensibility Module has stoped. Module Path: C:\Windows\system32\athihvs.dll.
I do not know what either of these mean or why they would occur..
Thank you again for any assistance.. I am apparently very error prone.
