Update Wireless Adapter Intel 7260

Question

I am trying to upgrade the wireless card in my Toshiba Portege from an Intel Centrino N2230 to an Intel 7260 card, but currently it is not working. My OS version is Ubuntu 14.04 LTS and here are some further details:

uname -a

I have so far attempted to download, extract, and copy the firmware into /lib/firmware as described in the last solution to this post: No wireless for Intel Corporation 7260 version 63

Please refer to this link. As per that Intel certifies Linux kernel 4.2 onwards for that wifi card. As per your logs you are still on linux kernel 3.13 which is not certified by Intel and may not work even after work around that you are trying to do.

So my advice is to upgrade to Ubuntu Desktop 15.10 which has Linux kernel 4.2 and it will work.

I had Intel 3165 and struggled a lot with Ubuntu Desktop 14.04 LTS. Finally i decided to fresh install Ubuntu 15.10 and that fixed the problem. Same i will suggest for you - it will save time and efforts.

You can refer to my thread here

I could only fix it by installing Ubuntu 15.10 which comes with Kernel 4.1/4.2. With the upgraded kernel in Ubuntu Desktop 14.04 LTS i used to get some what intermittent connection issues with the work around suggested in that thread.

When you are installing Ubuntu 15.10 - i will suggest connect your laptop via Ethernet cable. Once everything is installed then you can test your wifi card also. It should work.

I suggest you try newer firmware. With a working internet connection, please open a terminal and do:

sudo apt-get update
sudo apt-get install git
git clone https://github.com/OpenELEC/iwlwifi-firmware.git
cd iwlwifi-firmware/firmware
sudo cp iwlwifi-7260*  /lib/firmware

Reboot and see if the wireless is now working.
