Firmware for (Network controller: Intel Corporation Wireless 7260 (rev 73)) 5.4.0-113-generic

[Wawa1]

Hy

I ve had problems with the wifi connection after a few days of using Linux Mint. The wifi connection was shown up on an icon but i was not able to get online. Also a connection with a cable was not possible. So I installed Linux again. I assume the problem is the wifi chip. Is it possible to download a firmware for this specific adapter? I am using a 5.4.0 kernel.

Please excuse my English, also I am an absolute beginner on this field. I would be very happy for suggestions and any help.

Wawa1, Thank you for posting in the Intel® Communities Support.

In order for us to provide the most accurate assistance on this matter and answer your questions, we just wanted to confirm a few details about your system:

What is the model of the motherboard?

If this is a laptop, what is the model of it?

What is the model of the Router?

Is this a new computer?

Was the Wireless connection working fine before?

If so, when did the issue start?

Did you make any recent hardware/software changes that might cause this issue?

The wireless card, did you purchase it separately or did it come installed on the computer?

Does the problem happen at home or in the work environment?

Please attach the SSU report so we can verify further details about the components in your platform, check all the options in the report including the one that says "3rd party software logs":

Wawa1, You are very welcome, thank you very much for providing that information.

"first of all I am not able to run the SSU report", no problem at all, thank you very much for trying.

There are some troubleshooting steps that we recommend to try while using Linux as Operating System:

WiFi troubleshooting steps

Step 1: Check whether the kernel version customer uses supports this device:

The reference table of Wireless adapters and corresponding kernel versions is available by the link: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

The latest FWs are available by the following link:​ ​https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

If the kernel version corresponds to the Wireless adapter, proceed with step 2.

Step 2: Check whether the Wireless adapter is connected correctly:

Type the following command to the terminal: # lspci​ 

Verify that the Intel network controller ​is identified, as on a picture below. If not, then the system doesn't identify the Intel network adapter and you will need to make sure it's properly integrated. You may need to request help from the system manufacturer. If the wireless adapter is properly identified - proceed with the step 3.

Step 3: Check whether this is an iwlwifi issue:

Type the following command to the terminal: # modinfo iwlwifi​ (example of the command output is on the picture below). If there is no output, then the module isn’t installed this is the distribution installation issue.

Please type: # lsmod | grep iwlwifi​    

If the result is empty, the driver hasn't been loaded. Most likely to be a distribution issue.

To verify, please type: # dmesg | grep iwlwifi​    

If the result is empty, the driver wasn’t initialized and this is a distribution issue. If the result is populated as on the above picture, proceeed with the step 4.

Step 4: Check whether the suitable firmware is installed:

Please type: # dmesg | grep “no suitable firmware found!”​

If the result is not empty, it means you don't have a suitable FW (api mentioned in the dmesg).

Please visit here​ h​ttps://wireless.wiki.kernel.org/en/users/drivers/iwlwifi ​for supported FW, or here​ ​https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ for the latest versions.

If these steps didn't reveal the issue or didn't solve the problem, proceed with the Step 5: 

Step 5: Collect the debug data:

Please type: # dmesg | grep ASSERT​ 

If the output is empty, please follow this wiki: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging ​to extract dmesg and trace-cmd.

If the output has value, please collect from the wiki FW dump too.
