Hello all, I will first start off with I observed this issue with this hardware on OpenSUSE Tumbleweed as well, so it’s not specific to just Fedora. However, I have recently installed Fedora Kinoite 41 on this hardware, and am still seeing the issue.
Here is the output of lspci | grep -i wireless:
03:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)
When I experience the problem, here is the relevant dmesg output:

That last message will repeat for infinity until one of two actions are taken, either I reboot the system, or, I issue the following commands:
echo 1 > /sys/bus/pci/devices/0000\:03\:00.0/remove
echo 1 > /sys/bus/pci/rescan
killall wpa_supplicant
However, the issue will recur after a bit. Timing doesn’t seem to be an issue, it seems to come up during heavy network usage (installing updates, or installing an application, running a speed test, etc).
I have managed to get the network connectivity to be stable by creating a file in /etc/modprobe.d with the following options: (and I have run dracut -f and rebooted afterwards)
options iwlwifi power_save=0
options iwlwifi 11n_disable=1
#options iwlwifi 11ac_disable=1
#options iwlwifi swcrypto=1
options iwlwifi uapsd_disable=1
The commented out options are through process of elimination, trying to see what combination worked to get this stabilized. I have swcrypto commented out as I saw a message in the log that disabling hardware crypto is not supported for this chipset, so I figured it did not good calling that option anyways.
Despite the fact that the network connectivity is stable with this combination, it is incredibly slow. I was getting anywhere between 100-300mbps speeds previously, whereas with the above options I’m getting 2-3mbps speeds. Ultimately, I’m looking to see if there is a way we can get this back to full speed and stable.
My wifi network is a mesh system using tp-link deco W7200 devices. I don’t have issues with any other systems on this network, including a ThinkPad T420 and X250, both older ThinkPad devices. I do have Fast Roaming and Beamforming enabled on the network.
Now, it could very well be a hardware problem, or maybe a bug in firmware (which I understand this hardware is no longer supported and the firmware level is maxed out at the .17 release if I recall correctly).
Another option I’ve considered is disabling ax on the options and trying that, but I figured I’d seek help at this point. Any guidance would be appreciated, and I’m happy to provide additional info, just let me know what you might need and I’ll share it. Thanks in advance!
