I recently bought a Toshiba NB255-N245 and installed 11.04 with Wubi. It's working great, except that the Fn+F8 key, which should toggle the wifi on and off, does not have any effect in Ubuntu. It works fine in Windows 7. I'd like to be able to switch off sometimes to save battery, etc. Any ideas how to make it work? I tried rfkill block
, but the wifi light on the indicator panel stays on. Or if it's been turned off on the Windows side, rfkill unblock
won't turn it on.
EDIT:
As I said in a comment, sudo ifconfig wlan0 down
brings the wifi down temporarily, but then it comes back up after a few seconds.
I booted up again after having disabled wifi via Fn+F8 on the Windows side. Ubuntu boots up with the indicator light off. I tried rfkill unblock wifi
and rfkill unblock all
with no effect or message. ifconfig -a
does show wlan0, but sudo ifconfig wlan0 up
gives an error message:
SIOCSIFFLAGS: Operation not possible due to RF-kill
This machine has an Atheros chipset, BTW. lspci
reports:
07:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
I noticed that the network panel applet reports "wireless is disabled by hardware switch".
EDIT 2:
I found a bug report for this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/764524
ifconfig
andsudo
. Can you do me a favor and attach the output ofifconfig -a
to your question?wlan0
, if that's what you're getting at. I can't remember if I tried that, but I suspect that won't do any more thanrfkill
did.sudo ifconfig wlan0 down
and see what happens
