Everything was working fine till yesterday but when I did apt-get update and then apt-get upgrade , it downloaded 180mb of data from the internet . I am having BT4 Final with dual boot . After that when i rebooted the wireless card doesnt seems to work , when i open WICD it says No wireless networks found . Also the wireless light on the laptop is not blinking as it used to be before .

When i did cat /var/log/wicd/wicd.log , i can see the following related thing .

2010/11/25 16:10:37 :: WARNING: No path found for ktsuss
