I am trying to activate my wireless network card but all I get is:
Determining IP information for wlan0... failed.

When I type iwlist wlan0 scan into Terminal this is what I get:

[root@localhost ~]# iwlist wlan0 scan
Warning: Driver for device wlan0 recommend version 18 of Wireless Extension,
but has been compiled with version 17, therefore some driver features
may not be available...

wlan0 Scan completed :

As you can see I have turned off all Encryption and I have set Fedora up for Auto and Ad-Hoc and Auto also set the Network name (ESSID) up for Bardells
But I still get the same error when trying to adtivate it Determining IP information for wlan0... failed.

Has anyone any ideas??
