Latest Fedora update made Wi-Fi unusable

The latest update completely broke my Wi-Fi and made the system practically unusable.

After updating, the connection dropped to speeds in the KB/s range. I couldn’t even load my router configuration page or any static/local site reliably. Latency was extremely high and everything took forever to respond. The network was basically unusable.

I had to do an urgent rpm-ostree rollback to restore a working connection.

For reference, these are the package changes between the broken deployment and the rollback:

My main suspects are:

  • linux-firmware

  • iwlwifi firmware

  • or kernel 6.19.7

If anyone else is seeing extremely slow or unstable Wi-Fi after this update, it might be related.

For now I’m staying on the previous deployment until it’s clear which package caused it.

06:00.0 Network controller [0280]: MEDIATEK Corp. MT7921K (RZ608) Wi-Fi 6E 80MHz
Kernel driver in use: mt7921e

I think I solved it, I just upgraded again but reverted the router to 2.4GHZ instead of 5GHZ, very strange

Strange but I’ve noticed major driver instability on Meteor Lake since that update. Not just performance but frequent kernel memory spikes that take up all of my 32GB in a few seconds and reset the iwlwifi driver. I have other devices with Tiger Lake and older Intel platforms that don’t have any issues but the BE20x wifi seems to be affected. I needed to rollback firmware on Meteor Lake BE203.

A dnf downgrade linux-firmware sorted it. I’ve yet to isolate which package actually causes it but likely one of these:
```
Replaced iwlwifi-dvm-firmware-0:20260309-1.fc43.noarch Group @System
Replaced iwlwifi-mld-firmware-0:20260309-1.fc43.noarch Dependency @System
Replaced iwlwifi-mvm-firmware-0:20260309-1.fc43.noarch Group @System
```
If anybody else on Meteor Lake has issues, this is probably a firmware regression.
