I just enabled wireless by "ifconfig wlan0 up" and I now have my wireless working again :) Mark this as solved.
I have a Dell Mini with Ubuntu 8.10 on it. I am having trouble getting Ubuntu to recognize my Wireless card. I checked the hardware drivers section in the Administration menu and it lists the Atheros driver as being enabled. But I don't see any wireless networks. Based on some advice, I installed wicd, but that didn't help either.  When I run "lshw -C network", it lists my Atheros card (AR242x), but as network UNCLAIMED. How am I supposed to solve this?  EDIT: After further reading, I installed linux-backports-modules-intrepid, disabled the default Atheros wireless drivers, and left the Atheros 5xxx drivers enabled. lshw now lists my Atheros card as "network DISABLED".   I am not sure if this question has been asked before. If there is a post describing a solution for this problem, I would appreciate it if you can point me in the right direction.
