Installing drivers

I have installed this card in the NUC. The Bluetooth seems to be detected.

root@marvin:~# rfkill list
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

I have installed various drivers in /lib/firmware/:

following instruction for iwlwifi

# apt-get update && apt-get install firmware-iwlwifi


root@marvin:~# ls -al /lib/firmware/
total 9220

but also installing manually using Intel Wireless 7260 drivers

-rw-r--r--  1 root root 683236 Oct  8 07:45 iwlwifi-7260-7.ucode
-rw-r--r--  1 root root 679780 Oct  8 07:47 iwlwifi-7260-8.ucode
-rw-r--r--  1 root root 681464 Oct  8 07:47 iwlwifi-7260-9.ucode

After reboot, the wireless adapter is still not detected.

How can I make sure that my iwlwifi drivers are loaded?

dmesg doesn't show any errors, iwlwifi doesn't show up either (?). I figured I should see an entry for iwlwifi after copying the driver in /lib/firmware

dmesg after resolution

# dmesg | grep wifi

  • Check the dmesg output, maybe there are error messages in there that might help to diagnose the issue.

  • I don't see any issues there. I will upload the output of dmesg to the question. I am wondering is there is some kind of kernel config. I have been reading here that there is some rules to load firmware ... but this is really totally new to me.

  • I can upload the output of dmesg, it's too long, but there isn't any errors in there and it doesn't seem to be loading the iwlwifi drivers either ... may be that's the issue (??)

    Hmm, maybe your kernel is too old. wireless.kernel.org/en/users/Drivers/iwlwifi says "Intel® Wireless 7260 (3.10)", so you'll need at least Linux 3.10. Set up Debian backports, and install a newer kernel: aptitude -t wheezy-backports install linux-image-amd64.

  • Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux
  • 867Mbps 802.11ac Intel 7260 card, Dual band 5GHz + 2.4GHz Wireless 2x2 AC + Bluetooth4.0

Your kernel is too old. http://wireless.kernel.org/en/users/Drivers/iwlwifi says "Intel® Wireless 7260 (3.10)", so you'll need at least Linux 3.10.

Set up Debian backports, and install a newer kernel:
