[SOLVED] AR9285 Hard-blocked Mint14 Cinnamon 64bit

Postby GyroTech on Tue Jan 22, 2013 12:20 pm

I have an Atheros AR9285 in an HP ProBook 4530s and I cannot get it to work.

It seems that there is a hardware block somewhere:
Code: Select all
$ sudo rfkill list all
0: hp-wifi: Wireless LAN
   Soft blocked: no
   Hard blocked: no
1: hp-bluetooth: Bluetooth
   Soft blocked: no
   Hard blocked: no
2: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no
3: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: yes


But it is not the physical wireless button, as pressing that turns on a hard block (for wifi and bluetooth):
Code: Select all
$ sudo rfkill list all
0: hp-wifi: Wireless LAN
   Soft blocked: no
   Hard blocked: yes
1: hp-bluetooth: Bluetooth
   Soft blocked: no
   Hard blocked: yes
2: hci0: Bluetooth
   Soft blocked: no
   Hard blocked: no
3: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: yes


And lshw shows it as disabled:
Code: Select all
$ sudo lshw -c network

I have tried resetting my BIOS to factory defaults, I have also added the line options ath9k nohwcrypt=1 to /etc/modprobe.d/ath9k.conf but the phy0 was still listed as hard-blocked...

I have installed the linux-backports-modules-cw-3.6-quantal-generic and linux-backports-modules-cw-3.6-3.5.0-22-generic packages but they have not helped either.

Can someone suggest any more things I can try? Thanks.

Turns out having an ethernet cable connected acts as a hardware block to the wifi, as soon as I physically disconnected the ethernet, my wifi connection sprang into life...

Damn I feel dumb from this one :D
