Hi Troy, Thanks for your message. I tried NetworkManagerInfo last night, and as you said might happen, the kernel hung :( What I did was to go to System_Settings -> Server_Settings -> Services and started NetworkManager. It started with no problems. I then started NetworkManagerInfo and it gave me a few available wireless networks and their signal strengths. So far so good. I then typed in my SSID (which is hidden) and at this point it hung the machine. I was speaking to a linux expert and he was wondering if it has to do with the fact that it was a hidden n/w. It is quite possible that it might work if its an open network. Something that I will try when I get a chance. Thanks! Shri.
