something I've done recently (in the last few days) with updates seems to have killed my wifi (on an Intel wifi card). In the log file I have continual messages like

and if I do a ifup wlan0 from the command line, I get
- Code: Select all
$ ifup wlan0
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.

failed.
or it complains about the cable being disconnected...
Not sure where to go to try and fix this one, I've looked at the hardware in mcc which shows a Centrino Advanced-N 6200 as the device.
This was all working a few days ago, so its something recent that seems to have upset it.
Any ideas??
Life on the bleeding edge..
Always fun.Ta Peter.
