HI,
I recently installed Trisquel 6 on my Toshiba Satellite but it doesnt recognise the wireless adapter wich is an intel 5100 agn, i google it and installed the iwlwifi firmware to /lib/firmware and did
modprobe iwlwifi -r but still not working, when i do lshw -C Network this is what it shows:

btw trisquel is supossed to be based upon ubuntu 12.04

my uname -r is
root@soho-lap-01:/usr/share/wallpapers/EOS/contents/images# uname -r
3.2.0-48-generic-pae

Two module are requested to support the WiFi chip, driver and firmware. Based on the log, the driver is installed but firmware isn't.
At first, you need determine if your kernel currently has firmware loader support by looking for the CONFIG_FW_LOADER definition on your kernel's .config file.
Once you have the firmware loader in place (or if you aren't sure and you just want to try things to see if it works), you need to install the firmware file into the appropriate location.
Where that appropriate location is depends (again) on your system distribution. You can typically find this location by looking in the udev scripts of your distro, the default on most distributions is /lib/firmware.

Installation of the firmware is simply:
# cp iwlwifi-*.ucode /lib/firmware

I know this is a REALLY stupid question, but did you remember to unpack the downloaded firmware before you installed it to /lib/firmware?
