Heya y’all, a few weeks ago I made the switch to dual boot fedora and windows 11, and for the most part it’s been a fun experience, except for the wifi. On my (still active) windows install, my phone, and my tablet,
speedtest.net records about 100-200 Mbps on the same wifi within inches of each other, but on fedora I am lucky to get over 5 Mbps download and 2 Mbps upload. I am on fedora 37, Kernel 6.1.12-200.fc37.x86_64, this has been happening since I first installed, with I believe 6.1.9 or 6.1.8, and the command
$ lspci -k -n -n | grep -i -A 3 -e net
gives back this.

I do not have control over my router. If there is any other information you need, please let me know.

Intel doesn’t say the chipset would be supported.
If you have a look at
https://linux-hardware.org/?id=pci:8086-2725-8086-0024, you’ll see that there is still a lot of problems reported. Though, I can’t find you model
Have a look at
https://discussion.fedoraproject.org/t/intel-ax211-old-iwlwifi-driver-loading/77550/12 to find out how to create a hw probe.
Finally, I guess you just have to wait a bit for another firmware to be released…
Thank you! I made a hw probe and yeah I suppose its just a waiting game at this point.

I see hw probes at
https://linux-hardware.org/?id=pci:8086-51f0-8086-4090&page=1#status, but the probes don’t tell us how well the wifi works. You will want to compare linux wifi details with Windows and/or and older linux kernel
Collect some data – see
man 7 nmcli-examples.
doas nmcli dev wifi list shows BSSID’s, speeds, and channels.
check for wifi issues using
journalctl. Some users (myslef included) see a lot of disconnects, switching channels or AP’s with 6.1 kernels that didn’t occur with
Do you use 5Ghz wifi?
does performance increase when linux is booted from power-off?
Does your BIOS offer PXE boot options? Some systems activate wifi early to allow PXE booting (useful for big server farms, but also student labs).
