Intel 7265 WiFi not working

Hello,

I tried to get my Intel 7265 WiFi chip working with installing sudo apt install backport-iwlwifi-dkms also tried copying Intel provided drivers at Intel Driver Link into /lib/firmware folder but all these does not make it visible in network settings.

When I look into Additional Drivers in Software & Updates, I see it says Intel Corporation: Wireless 7265; Using iwlwifi driver back port in DKMS format from backport-iwlwifi-dkms (open source). With this shown, doesn’t that mean the driver is working and the WiFi should function well now?

Thank you.

Here is a screenshot of the Additional Drivers tab.

With further research, I have the following traces showing could not load the [0] uCode section.

I have solved it by following this link

Here is the steps:
sudo nano /boot/extlinux/extlinux.conf

Add “pcie_aspm=off” to the end of APPEND line
TIMEOUT 30
DEFAULT primary

MENU TITLE L4T boot options

LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
INITRD /boot/initrd
APPEND ${cbootargs} quiet pcie_aspm=off

Good to know issue resolved, thanks for the update!
