Hi all

Wonder if any one has a suggestion for me. I've wiped vista off my
laptop, an Acer Aspire 5920. and installed Schlutenscheisser. I've got
couple of problems but I'll just mention the wifi for now. On boot
something odd is happening to the wifi. As soon as the firmware loads
a hardware kill switch is activated.

$ dmesg | grep iwl

I have trawled the internet for help and have place a file called
iwl3945 in /etc/modprobe.d The file contains these two lines

alias wlan0 iwl3945
options iwl3945 disable_hw_scan=1

This was supposed to prevent the hardware switch from operating but
even if I unload and reload the module iwl3945 it gets HW killed
again. :-(

Any ideas, please?

Thanks in advance
