10.10 - intel 3945 wireless died!

[Stretchnuts]

I've been running ubuntu on my laptop for about 5 years now.
For pretty much every new release, the wlan goes down, and I've had to find some workaround to make it work.
Now that I've updated to 10.10, there seems to be nothing I can do?

Dmesg tells me the radio is disabled by the RF kill switch.
Rfkill says wlan isn't blocked in any way.

In xev, there is no input when I press the wlan button, nor when I press the key combo for it (Fn + F10).

Before the update to 10.10, I've used the acerhk module to enable radio:

sudo insmod /lib/modules/2.6.32.15+drm33.5/extra/acerhk.ko && echo 1 > /proc/driver/acerhk/wirelessled

Any idea what I can do to turn my wlan back on?

Hey, I had the same problem. When you do:

more /var/lib/NetworkManager/NetworkManager.state

I got:

[main]
NetworkingEnabled=true
WirelessEnabled=false
WWANEnabled=true

So I changed the setting:

sudo rfkill unblock all

And voila! All fixed. Wireless is back.

I hope this is helpful!
