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 9:46
    
Thanks! I edited the post now :) –  Fyksen Jul 21 '13 at 10:04
    
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

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. askubuntu.com/questions/331667/… 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

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 4:03
    
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: wireless.kernel.org/en/users/Drivers/… –  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.
