Description

Summary

After performing an update this morning, and rebooting, my wifi adapater is not able to connect to my home network. It has been working fine for years up until today. I can use wired ethernet through a dock as a workaround at home. Let me know if you need any other information.

Environment

Solus unstable repo
Plasma desktop
ThinkPad Lenovo X1 Carbon Gen 5 laptop
System was just updated this morning, checked for broken packages.
These were found and reinstalled:

linux-firmware
atom

Kernel
5.11.22-180.current

Wifi adapter is Device-2:

≻ inxi -N
Network:   Device-1: Intel Ethernet I219-LM driver: e1000e 
           Device-2: Intel Wireless 8265 / 8275 driver: iwlwifi 
           Device-3: Lenovo ThinkPad TBT 3 Dock type: USB driver: r8152

I'm going to try reverting to the previous kernel to see if that allows the device to connect

TClark77 updated the task description. (Show Details)

Likely related to R1964:73f13fe74dca: Update to 20210511 which included updated iwlwifi 8000 series firmware. While I recognize you aren't on the device called out in the topic of https://bugzilla.kernel.org/show_bug.cgi?id=203709, I did check that this affects 8265 as well and newer comments still indicate it being an issue in newer comments. Is this on a 5Ghz network or 2.4Ghz? Some are reporting better results on 2.4.

That's probably the cause.
Booting with kernel 5.11.21-179.current didn't change anything.

I had just tested switching between the two interfaces on our wifi network and found that I don't have any connection issues or kernel errors with our 2.4GHz network. The problem is always reproducible when I'm connected to our 5GHz network. I'll use our 2.4GHz network for now as a workaround.

So a funny thing happened on the way to the access point....

We noticed our phones here at the house were also having trouble with the 5G wifi network. There had been an update to our access point firmware the other day. I hadn't been seeing any issues on my laptop with the network since that update.

After rebooting the wifi router, the problem appears resolved on the phones and on the laptop. Don't ask me what combination of firmware gremlins was at fault, but things appear good on this machine for now. If no one else reports issues with this, feel free to close it out. I have a watch on the upstream issue.

This had been resolved.
