This is what I have so far:
#######################################
root# lspci:
05:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5906M Fast
Ethernet PCI Express (rev 02)
06:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless
Network Adapter (rev 01)
root# uname -a
2.6.31-2-generic #17-Ubuntu SMP Fri Jul 10 21:48:31 UTC 2009 i686 GNU/Linux
#######################################
Right after boot:
root# tail /sys/class/rfkill/*/state:
==> /sys/class/rfkill/rfkill0/state <==
0
==> /sys/class/rfkill/rfkill1/state <==
2
Wifi link down, NetworkManager shows the message "wireless is disabled" when
right clicking over it.
#######################################
After pressig the wifi button:
==> /sys/class/rfkill/rfkill0/state <==
1
==> /sys/class/rfkill/rfkill1/state <==
2
Wifi link still down, NetworkManager still shows the message "wireless is
disabled" when right clicking over it.
So, pressing my laptop's wifi key changes the state of "rfkill*" from 0 to 1
and vice-versa, but my wifi is always down.
#######################################
With my "rfkill0" state set to 0 (by pressing wifi key, not by manually editing
rfkill state), trying the module fix:
root# modprobe -r -f ath5k
root# modprobe ath5k
root# tail /sys/class/rfkill/*/state
==> /sys/class/rfkill/rfkill0/state <==
0
==> /sys/class/rfkill/rfkill2/state <==
2
THEN I PRESS WIFI KEY
root# tail /sys/class/rfkill/*/state
==> /sys/class/rfkill/rfkill0/state <==
1
==> /sys/class/rfkill/rfkill3/state <==
2
And still no wireless link.
#######################################
With my "rfkill0" state set to 1 (by pressing wifi key, not by manually editing
rfkill state), trying the module fix:
root# modprobe -r -f ath5k
root# modprobe ath5k
WIRELESS LINK COMES UP
root# tail /sys/class/rfkill/*/state
==> /sys/class/rfkill/rfkill0/state <==
1
==> /sys/class/rfkill/rfkill4/state <==
1
######################################
- I noticied that my "rfkill0" is alway there, but "rfkill2" changed to
"rfkill3" and then to "rfkill4".
- Pressing wifi key only changes the state of "rfkill0", not "rfkill>1".
- root# cat /sys/class/rfkill/rfkill0/name -> acer-wireless
- root# cat /sys/class/rfkill/rfkill4/name -> phy0
- In order make my wifi work I mus set BOTH rfkill to 1 and then press the
wifi key. rfkill0 can switched from 0 to 1 by pressing wifi key and rfkill1 can
be switched from 2 to one by removing then enabling back the ath5k module, but
rfkill1 changes to rfkill2.
- I tried many many forms of editing "state"... None of them worked. I Googled
a lot :(
- If I try editing (even if chmodding 777):
root:/sys/class/rfkill/rfkill0# write state 1
write: write: you have write permission turned off.
write: state is not logged in on 1
