No wireless for Intel Corporation 7260 version 63
Solution 1
I suggest you download this to your desktop: http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.11-rc3/backports-3.11-rc3-1.tar.bz2 Right-click it and select 'Extract Here.' Now open a terminal and do:
cd Desktop/backports-3.11-rc3-1/
make defconfig-iwlwifi
make
sudo make install
Now download the required firmware here: https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode Now open a terminal and do:
sudo cp ~/Desktop/iwlwifi-7260-7.ucode /lib/firmware/ <--or wherever you downloaded it
sudo modprobe -r iwldvm <--If it is not loaded, OK, please proceed
sudo modprobe -r iwlwifi <--If it is not loaded, OK, please proceed
sudo modprobe iwlwifi
Your wireless should now be working.
For those that can't get the ucode file from the above link use this link: http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005511.html
Solution 2
After installing Ubuntu 14.04 Trusty on my Dell Vostro 5470 laptop, I had the same problem. Installing the newest driver worked for me, no need for backports.
It can be found here: http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware
In the driver files, there is a Readme with instructions, but here is how to do it:
Download the driver on your Desktop: http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFile&do=get&target=iwlwifi-7260-ucode-22.24.8.0.tgz
Extract the contents on your Desktop.
sudo cp ~/Desktop/iwlwifi-7260-ucode-22.15.8.0/iwlwifi-7260-8.ucode /lib/firmware/
Restart.

I have a Dell XPS 12 running Ubuntu 13.10 and it doesn't appear to find it's wireless. I have tried the suggestions here but they made no difference

What I have found is that it appears to be loading an old version of the firmware but I don't know how or why
peter@xps:/lib/firmware$ modinfo iwlwifi | grep 7260 firmware: iwlwifi-7260-6.ucode peter@xps:/lib/firmware$ ls *7260-6* ls: cannot access *7260-6*: No such file or directory
Any suggestions of how to get this setup very welcome.

chili555 almost 11 yearsPlease confirm that you made the changes to iwl-7000.c, compiled backports-3.10.2 and loaded iwlwifi. What interesting clues are in: dmesg | grep iwl?
-
Peter Lawrey almost 11 yearsI believe it's the loading of the iwlwifi which failed as I see
iwlwifi-7260-6.ucode
is loaded. I had a versioniwlwifi-7260-7.ucode
already, and replacing it didn't help. Not sure why it doesn't load this anyway. -
chili555 almost 11 yearsThe change to iwl-7000.c is supposed to fix that. You might also rename -6.ucode to -6.bak so it can't load and see if it helps. You will need to unload and reload iwlwifi or reboot for the change to be effective.
-
chili555 almost 11 yearsWhat is the exact message in dmesg that says -6 is loading. Maybe we can deduce what to fix in iwl-7000.c. dmesg | grep -e firm -e ucode

rcomblen almost 11 yearsFor those who ask, the ucode file comes from the Debian package: packages.debian.org/fr/sid/firmware-iwlwifi
-
TechiRik over 10 yearsyeah that's what I actually meant :) thanks. I can update the kernel but I would have to reinstall the backport again
-
chili555 over 10 years@DmitryPashkevich- Exactly!
-
jhrs21 over 10 yearsFor those that prefer getting things from original sources, the firmware can be found at: wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware
-
Braiam over 10 yearsApparently the new 3.10 kernel should work just fine.
-
Noosrep over 10 yearsWorked also for me (12.04)
-
Sina over 10 yearsAlso worked for me with Advanced-N 6235
-
Tim about 9 years@chili555: +1. I have been plagued by a similar wireless adapter problem: askubuntu.com/questions/612138/… Could you take a look? Thanks.
-
Peng Zhang almost 9 yearsThis answer is great. Solves my problem of no wlan0 after removing 3.16 and installed 3.19. followed this answer, I download the backports 3.19 and the corresponding intel wifi firmware. The only difference I did is "make -j". saves me a little time though.
-
Adrian Keister about 7 yearsThis didn't work for me. Were there any additional steps you used?
-
venkatesan about 7 yearsNo, just these 4 steps. Now I am using 16.04 with the same laptop, and the wifi works out of the box.
