I'm experiencing a very strange issue at boot or after wake with the integrated 8265 chip of my ThinkPad X1. Unfortunately the chip is soldered on this model, so replacing it isn't an option.
On my Dell laptop with wifi6, also with Fedora 36, everything works perfectly fine.
On the ThinkPad, the iwl-8265 firmware is loaded and the chip is detected:
[ 18.034043] iwlwifi 0000:04:00.0: loaded firmware version 36.ca7b901d.0 8265-36.ucode op_mode iwlmvm
[ 18.285542] iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8265, REV=0x230
However, the actual connections just don't happen without retrying at least 3 and up to 10 times. It is an issue both on bluetooth with a mouse I paired and on wifi.
In both cases, the discovery of available devices / networks happens correctly. But then on bluetooth, the already paired device just remains disconnected until I disable and re-enable bluetooth a few times.
The wifi is similar, it lists the available networks, it keeps trying to connect to my network that I already saved. There it even manages to do a dhcp request, which is seen on the dhcp server. But NetworkManager just ends with "ip-config -> failed". After 5-10 retries, without changing anything, eventually it always connects.
With such non-deterministic behavior, I'm not even sure how I could diagnose the issue further. Does anyone have any ideas?
