No wireless with Intel Centrino Advanced-N 7260

Question

I have just bought a new laptop. Acer v7-582PG. Everything works great with Ubuntu, exept the wireless module. I have tried Ubuntu 13.04 and 13.10 Beta. Still no luck.

It is kind of a new wireless card, so there is very little information out about it.

You can add information if the card by editing your question. Paste output of following lspci , sudo lshw -c network, rfkill list all — Web-E, Jul 21 '13 at 09:46
Show us the output of nmcli con list, nmcli -p con up id "NAME" iface wlan0 and nmcli -p con status id "NAME" iface wlan0. Where NAME is the name of the wifi you want to connect to given by nmcli con list. — Benoît Legat, Jul 21 '13 at 11:00
since this is a new computer, and the wireless never have worked, I have no saved WLAN yet. — Fyksen, Jul 21 '13 at 11:09
I think this is supposed to work with the driver iwlwifi and appropriate firmware. Please load it and check for messages in the logs: sudo modprobe iwlwifi and then do: dmesg | grep iwl — chili555, Jul 21 '13 at 13:25
I'm not sure where I can find the correct firmwire. And I dont know how to load it ether. Can you point me in the right direction? — Fyksen, Jul 21 '13 at 13:51

Further research, primarily here, suggests that simply loading the firmware will be ineffective. http://forum.notebookreview.com/networking-wireless/716325-intel-7260-a-6.html

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 reboot and tell us if your wireless is working.

I tested in Ubuntu 13.04 and it compiles perfectly and correctly drives my Intel 6200, but I don't have a 7260 so I can't test further. Fingers crossed! You definitely need the firmware.

So is it working as expected? – chili555 Jul 22 '13 at 12:41
I tried this but it didn't make any difference – Peter Lawrey Aug 12 '13 at 13:14
@PeterLawrey ,what clues appear in: dmesg : grep iwl – chili555 Aug 12 '13 at 13:27
That doesn't return anything. http://askubuntu.com/questions/331667/no-wireless-for-intel-corporation-7260-version-63 suggests an old version of the firmware is being loaded. – Peter Lawrey Aug 12 '13 at 13:31

This does not work for Ubuntu 12.04 – Czarek Tomczak Oct 12 '13 at 17:27
I have a Dell Latitude with Wireless 7260 and Ubuntu 12.04. After loading the firmware and installing the backports as in your well-documented steps, it worked just fine. Thank you. – calico-cat Oct 25 '13 at 21:37
Just to mention, this worked for me, but gave me intermittent WiFi when internet traffic was high (I had to toggle wifi to get signal back), and gave lots of errors in syslog. I believe the bug is reported here: https://bugzilla.kernel.org/show_bug.cgi?id=66001, and the updated firmware mentioned in that thread seems (at least so far) to have fixed it for me. – fpghost Dec 20 '13 at 20:59
Is there a way to update the driver automatically using this method? Just noticed that there are more recent kernel versions available (up to 3.13.2). – Iain Samuel McLean Elder Mar 26 '14 at 22:56
@IainElder The default kernel in 13.10 includes the alias for the device: 8086:08b1. All you should need is the firmware. – chili555 Mar 26 '14 at 23:04
I'm running 12.04 LTS because LTS seemed to have better "support" (longer anyway). Guess I need to use the latest and greatest to get good support for new hardware! Thanks for your help. – Iain Samuel McLean Elder Mar 26 '14 at 23:08
Generating local configuration database from kernel ...Kernel version parse failed! Makefile:40: recipe for target 'install' failed make: *** [install] Error 1 ``` . The above error is coming in my case – Rudresh Dixit Dec 06 '19 at 21:28
@RudreshDixit Please start your own new question. Include the result of: lsb_release -a I wonder if you have a kernel later than 3.13 making this driver ineffeftive. – chili555 Dec 06 '19 at 22:04

Although you didn't confirm it from dmesg, it appears you need and lack the required firmware. Here is a link from my Dropbox: https://dl.dropboxusercontent.com/u/58267392/iwlwifi-7260-7.ucode.zip Please download it to your desktop. Right-click and select 'Extract Here.' Now open a terminal and do:

sudo cp Desktop/iwlwifi-7260-7.ucode /lib/firmware/
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

Do you have a wireless interface now?

iwconfig

Does it connect? Are there any informative messages here?

dmesg | grep iwl

None of that worked for me, but downloading and installing linux-3.11.0-rc4, your link to the iwlwifi-7260-7.ucode, and putting it in /lib/firmware worked! Thanks! – wulftone Aug 12 '13 at 04:03
This one works on Ubuntu 12.04. But I'm wondering if this will work stable as the "iwlwifi-7260-7.ucode" is for Kernel 3.10+ and ubuntu 12.04.3 kernel is 3.8. The iwlwifi-7260-7.ucode can be downloaded from kernel.org: http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFile&do=get&target=iwlwifi-7260-ucode-22.0.7.0.tgz – Czarek Tomczak Oct 12 '13 at 17:36
Before this, you have to do the steps in the other chili555 answer, the "make defconfig-iwlwifi" steps. Also after you got updates to the Kernel, your wifi will stop working again, you have to repeat the "make" steps and reboot. – Czarek Tomczak Oct 12 '13 at 20:18

I tried installing both of those packages (the backport and the iwlwifi-7260-7.ucode), but my computer still isn't detecting a wireless card.

The guy above said it worked by downloading and installing linux-3.11.0-rc4 . Can someone please give instructions on how to do this? Like, how do I add the repository, download it, and install it? Help would be greatly appreciated, as I need to use Linux on this computer for work. Thanks

according to http://wireless.kernel.org/en/users/Drivers/iwlwifi , it seems we need a kernel-upgrade; Ubuntu 13.04 use 3.8.0 by default, which can't support n7260

wait for Ubuntu 13.10 is another solution...

I'm upgrading my kernel now ;(

I upgraded to the kernel 3.11-8 and both of the network connections work 'out of the box'.

When upgrading you might have a warning such as firmware possibly missing with names of different files needed: I fixed it with apt-file search name_of_the_file and this for each file "probably missing".

In order that your wireless card be detected - you have to go to "System Settings" -> "Additional Drivers" and Activate (turn button from grey to green) for your card. On some RTL cards there can be 2-3 or more drivers (I had on my Dell Inspiron 6400) :( - in that case try to turn off one that is not working and turn one next one - until you found right one :(((. Eorked for me (was just 3 ;-))

Hopefully this will help

I am using the same hardware as you

   description: Wireless interface
   product: Wireless 7260

Kernel version is

$ uname -a Linux nanak-P570WM 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

I am using Wireless since long.

Please install the above Kernel version from

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/

It should work.
