Any advice or suggestions on how to eliminate this issue is most appreciated..Ive researched all day and have yet to find a solution..Thank You!


SOLUTION:Using these commands fixed the issue...Just make sure you specify the drivers of your interface..

rmmod ath5k
rfkill block all
rfkill unblock all
modprobe ath5k
rfkill unblock all
ifconfig wlan0 up

Hope this helps any others out there with same issue!

LIKE TO STATE THIS SOLUTION ONLY WORKED 1 DAY FOR ME!! LOL SO IM STILL OPEN TO SUGGESTIONS ON WHAT TO DO.

Something from my experience:

23:39:25 <mr00wka@r2d2>[~] rfkill list
0: tpacpi_bluetooth_sw: Bluetooth

Soft blocked: yes
Hard blocked: yes

<b>1: phy0: Wireless LAN

Soft blocked: yes
Hard blocked: no

</b>


Now if I knew WHAT software is blocking this device I could probably disable it permanently. It might be the same in your case.... Anyhow, after running rfkill unblock all my wireless is working perfectly

Thanks very much!!!

After two days messing about, "rfkill unblock all" worked for me (you need to do it after every start up).

Now both:-
Ralink rt2501usb
Netgear rtl8187

have both started working on 9.10 (they both work out-of-the-box on 9.04)

This didn't work for me. Still showing as disabled.

Using Broadcom4318. I think this might be the Satan of wireless cards after trying for the past day to figure this out.

EDIT:
It's showing up under *-network:1 as opposed to wlan0...could this be an issue? Also the driver is listed as b43-pci-bridge but it's not a PCI card...

Any news on how to find a solutions to this problem?

[<hidden>]

Demn... So many stupid replies to all the related bug-reports and everybody saying it's not my falt/It's not my problem/It's BIOS problem/It's wicd problem/It's NetworkManager problem/It's b43-fwcutter/Blah Blah Blah

The only real solution is on Russian Site, of course, where else...
