I run (K)Ubuntu 12.10/12.04 in a triple boot with Windows 7 and access the Intenet wirelessly. This works perfectly most of the time. Sometimes after a normal reboot, the wireless connection dissapears. In Ubuntu, it manifests itself in "Device not ready" being shown in Network Manager, and in Kubuntu, the WLAN Interface is "Unavailable" in the corresponding KDE Network Manager widget. Normally, when available, my wireless connection's SSID is displayed and I automatically get connected to it.

At this point, the only thing that helps me get back the wireless is booting in and out of Windows 7 and then back to (K)Ubuntu. However, I would like to be able to fix the problem without having to rely on Windows 7 being there.

Below are some relevant command outputs I've used for debugging

I've tried to bring the wireless up manually with

[code36g0te95]sudo ifconfig wlan0 up[/code36g0te95]

and got the following output

[code36g0te95]SIOCSIFFLAGS: Input/output error[/code36g0te95]

I've found the following entries in syslog interesting (logged when a boot results in a non-functional wireless)

OBSERVATIONS
1. Wireless appears to be lost randomly sometimes on a reboot (both after installing some updates and also when none were installed before the reboot)
2. When it is lost in one of the (K)Ubuntu's, it is also unavailable in the other one after booting into it
3. The only thing that brings back the wireless is rebooting into Windows 7 and back
How can I re-enable my wireless in this case?

I will happelly provide more details if needed!

Kind Regards,
Sven
