Wireless not working
The network manager in upper right does show available wireless networks but selecting them does not seem to work. When I do ifconfig, wlan0 does not show an IP address. The hardware should work because it worked fine until I tried to switch from my work wireless to my home wireless.
when I try a command like:
$ iwconfig wlan0 ap any
I get this as a response:
Error for wireless request "Set AP Address" (8B14) :
SET failed on device wlan0 ; Operation not permitted.
I also get a permissions error when I try ifup
$ ifup wlan0
ifup: failed to open statefile /var/run/network/ifstate: Permission denied
I am the admin on my computer so not sure the reason for these errors. I am on Ubuntu 7.10. How can I get my machine to recognize the wireless networks, manually or otherwise? Thanks so much for your help!!
