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
[...]
[ 39.148650] firmware: requesting iwlwifi-3945-1.ucode [ 39.273994] iwl3945: Radio disabled by HW RF Kill switch [ 46.197829] iwl3945: Radio disabled by HW RF Kill switch [ 50.178462] iwl3945: Radio disabled by HW RF Kill switch [ 54.187015] iwl3945: Radio disabled by HW RF Kill switch [ 235.037523] iwl3945: Radio disabled by HW RF Kill switch [ 237.703345] iwl3945: Radio disabled by HW RF Kill switch
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. :-(
First of all: are you *sure* that the hardware switch is on? :)
Then check out /sys/class/net/$WLAN_DEVICE/device/rfkill/... (and play with it using the disable=1 option for the iwl driver)
