WiFi Card disappearing from eeepc 1215N..

[Krakken]

Hi everyone,
I experienced this proble a couple of times before upgrading to Ubuntu 12.04 and now, 5 days after succesfull upgrade is back and I cannot solve it.

I own a eeepc 1215N with Ubuntu 12.04 now, and while surfing the web once in a while the wireless signal disappears. At that point the wireless option in the connectivity menu is not longer listed, and also after booting there is no sign of wifi connectivity. The sad part is that under windows it works perfectly.

Here are the output of my lspci:

Well I've experienced lots of trouble with broadcom wireless adapters what might help is to re-/install the driver: http://askubuntu.com/questions/12763...s-card-working
