Intel 7265 WiFi

General system Kernel, boot, graphics & hardware

Following me updating my system last Friday I had sporadic and sometimes non existent WiFi on the Linux LTS kernel and the Linux kernel, below is the output of inxi -Nza

jon@cogen-z600 ~ >> inxi -Nza
Network:
  Device-1: Broadcom NetXtreme BCM5764M Gigabit Ethernet PCIe
    vendor: Hewlett-Packard driver: tg3 v: kernel pcie: gen: 1 speed: 2.5 GT/s
    lanes: 1 port: N/A bus-ID: 01:00.0 chip-ID: 14e4:1684 class-ID: 0200
  Device-2: Intel Wireless 7265 driver: iwlwifi v: kernel pcie: gen: 1
    speed: 2.5 GT/s lanes: 1 bus-ID: 28:00.0 chip-ID: 8086:095a class-ID: 0280

To troubleshoot the issue I first rolled back the intel-ucode package from intel-ucode-20240813-2 to intel-ucode-20240531-1.

That showed some improvement but it would still drop the WiFi not very long after. I then thought that network manager may be the issue so tried that, I downgraded network manager from networkmanager-1.48.8-1-x86_64 to networkmanager-1.48.6-1-x86_64 and networkmanager-qt-6.5.0-1-x86_64 to networkmanager-qt-6.4.0-1-x86_64

No real difference doing that so I then downgraded the LTS kernel from linux-lts-6.6.48-1-x86_64 to linux-lts-6.6.44-3-x86_64. It seemed like that worked but within 10 minutes it had dropped again and was cycling the connection constantly.

Looking at dmesg it shows constant reconfiguring

I’m stuck now. My only other thought is that it is a KDE problem, but I don’t really want the hassle of down grading everything. At the moment I’ve had to break out my Powerline ethernet units to at least have access to the Internet on this machine.

You could try some of these parameters. You’ll need to create the file in /etc/modprobe.d/iwl.conf

ADD

   options iwlwifi 11n_disable=1
   options iwlwifi swcrypto=0
   options iwlwifi bt_coex_active=0
   options iwlwifi power_save=0
   options iwlwifi uapsd_disable=1

   options iwlmvm power_scheme=1

Edit: These are a few and there are others. You can try one at a time and see if any of them resolve your issue. I think you would need to add them and reboot in order to test.

In addition to the above, I may have the same issue and what I did was to downgrade the below packages based on the discussion linked below:

sudo downgrade iwd ell

Discussion: https://gitlab.archlinux.org/archlinux/packaging/packages/iwd/-/issues/5

Note that if you downgrade, you should pay attention to updates related to any ignored packages. Basically, look for something new that may fix the issue, or bookmark the thread linked to track if there are any other fixes.

A downgrade is only a temporary fix.

Related discussion: https://gitlab.archlinux.org/archlinux/packaging/packages/ell/-/issues/1

I’m now fully up-to-date except for those packages with stable Wi-Fi.

Same issue here since last Friday. I switched to Connman until the problem is fixed.
Maybe I’ll give the Downgrade a try.

Thanks for all the replies, I’ll have a look tomorrow as much rum has been consumed with and while making risotto :beers:

The iwd package got an update some hours ago. I upgraded and all is well now. You may want to try another upgrade. :wink:

@Moon You may not need to bother trying the downgrade workaround.
