I recently installed Ubuntu 11.04 on my desktop, but when I start up the computer the wireless doesn't work. I know this is a popular question, I did a search and people seems to have trouble with software/hardware block, or driver issue... But none of them seems applicable to me.
If I click on the network icon at the top right corner, it shows wireless as "disconnected" but it doesn't list available networks. If I uncheck/check the "Enable Wireless" option to reset, the option will stay as "disabled". If I uncheck/check the "Enable Networking" to reset the network interface, then the wireless shows as "device not ready".
If I run sudo rfkill list all, wireless shows as soft blocked: no and hard blocked: no. If I run lshw -C network, wireless shows as DISABLED, and driver shows as rt2800pci. If I run nm-tool, there are no wireless access points listed.
Thus I know my wireless card has a proper driver, it is not soft/hard blocked, and my desktop shouldn't have any hardware switch...
So what other steps I can go to trouble shoot this issue??
