## Adding a WIFI adapter

Tue Apr 05, 2016 10:18 pm

I have an Intel Pro Wireless 4965 adapter in my laptop
Found a driver in /home/user/wireless-driver, so installed "firmware-iwlwifi"
Install went ok, when I do " modprobe iwlwifi" , it does not complain.
however, I have no idea how to setup the usual wifi interface, "wlan0" or how to get it work
any suggestion?
thanks!

Easy way is first, get the name of your wireless-capable network devices (after installing the firmware)
(in a terminal)
su
iwconfig
Then open wicd, set it in preferences, refresh, enter key for your network, then just connect!

Best guess is, you got the wrong firmware. Mine is ralink on one machine, iwlwifi on another, both work no problem. Check your device. on https://wiki.debian.org/WiFi .. Note (after the firmware is in) it's not always wlan0.
One quite new Dell I set up for a friend needed a newer kernel for wireless, hopefully for you that won't be the case.

managed to boot up from an USB, with another debian disro , where wifi works fine
lshw -c network showed:

I guess, my problem is the "UNCLAIMED" status
does it mean no driver or not a correct driver installed ?
thanks

https://wiki.debian.org/iwlegacy#supported
Note it says,

Code:
  `# modprobe -r iwl3945 iwl4965
  # modprobe iwl3945 ; modprobe iwl4965`

It might make a difference whether you booted with it already installed or not. Other distros which ship with preinstalled non-free might have lawyers on their payroll and/or have different opinions on software freedom.
