Intel wireless ac 7260 driver linux

What driver for Intel AC 7260 adapter

My notebook has the infamous Intel AC 7260 adapter and after a few days the adapter just stopped working e.g. (The adapter can see the ap but can not connect when it connects it is connected for short time and than disconnects also it can’t connect after disconnects), maybe it is because I ran apt-get update but I’m not sure. I can’t connect to ap I checked the version of the driver

ls /lib/firmware/iwlwifi-7260* 

/lib/firmware/iwlwifi-7260-7.ucode /lib/firmware/iwlwifi-7260-8.ucode /lib/firmware/iwlwifi-7260-9.ucode 

so I’m not sure which version of the driver the OS is using. Is it 7,8 or 9? I checked the Intel site and there is a version 9 for my kernel. I’m not sure if I should delete all 3 and get a new driver from Intel

The driver is iwlwifi . Check modinfo :

filename: /lib/modules/4.0.1-040001-generic/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko license: GPL author: Copyright(c) 2003- 2014 Intel Corporation description: Intel(R) Wireless WiFi driver for Linux firmware: iwlwifi-100-5.ucode firmware: iwlwifi-1000-5.ucode firmware: iwlwifi-135-6.ucode firmware: iwlwifi-105-6.ucode firmware: iwlwifi-2030-6.ucode firmware: iwlwifi-2000-6.ucode firmware: iwlwifi-5150-2.ucode firmware: iwlwifi-5000-5.ucode firmware: iwlwifi-6000g2b-6.ucode firmware: iwlwifi-6000g2a-5.ucode firmware: iwlwifi-6050-5.ucode firmware: iwlwifi-6000-4.ucode firmware: iwlwifi-7265D-10.ucode firmware: iwlwifi-7265-10.ucode firmware: iwlwifi-3165-10.ucode firmware: iwlwifi-3160-10.ucode firmware: iwlwifi-7260-10.ucode firmware: iwlwifi-8000-10.ucode

Your results will vary if you are using a different kernel version.

You can determine the version being loaded, generally the latest, in your case -9, from dmesg :

You will probably see something like:

loaded firmware version 25.228.9.0 op_mode iwlmvm 

This corresponds to -9 firmware.

Please edit your question to add more details about your wireless beyond, «. just stopped working.»

I suggest you update the driver to enable the use of the later firmware. Please download this file to your desktop: https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.0.1/backports-4.0.1-1.tar.xz Right-click it and select ‘Extract Here.’ Now, in a terminal, and with a temporary internet connection, do:

sudo apt-get install linux-headers-generic build-essential cd ~/Desktop/backports-4.0.1.1 make defconfig-iwlwifi make sudo make install 

Now we need the latest firmware. Please download this to your desktop: http://www.linuxwireless.org/attachments/en/users/Drivers/iwlwifi/iwlwifi-7260-ucode-23.11.10.0.tgz Right-click it and select ‘Extract Here.’ Now, in a terminal, do:

cd ~/Desktop/iwlwifi-7260-ucode-23.11.10.0 sudo cp iwlwifi-7260-10.ucode /lib/firmware 

Next, in my experience, the driver iwlwifi is somewhat access point sensitive. I have experimented and honed a few techniques.

First, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Next, I recommend that your regulatory domain be set explicitly. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Set it permanently:

gksudo gedit /etc/default/crda 

Use nano or kate or leafpad if you don’t have the text editor gedit.

Change the last line to read:

Of course, substitute your country code if not Iceland. Proofread carefully, save and close the text editor.

Reboot and let us know the result.
