I have this issue with resuming from sleep. It seems to take about 35 seconds to resume from sleep and wake the screen.

At the 35 second mark, I see usb devices and the keyboard backlights flash, like they have been reinitialized, and then I see the display finally turn on. After unlocking, dmesg shows kernel backtraces.

I have tried to enable rtc_cmos.use_acpi_alarm=1 in the kernel command line parameters, like discussed in https://github.com/linux4life798/framework-linux-docs/blob/main/ubuntu-22.04-fw-16.md#suspend-keeps-waking-up-or-fails-to-suspend, but it doesn't make a difference.

Also, this pinned firmware version for the Mediatek MT7922 still doesn't fix the issue with wifi 6e most of the time.

It looks like there has been quite a few more updated to the mediatek firmware, since the 0a18a7292a66532633d9586521f0b954c68a9fbc version.

I'll try the latest tag 20240410:

pushd ~/Downloads
gio trash WIFI_*.bin
wget https://gitlab.com/kernel-firmware/linux-firmware/-/raw/20240410/mediatek/WIFI_MT7922_patch_mcu_1_1_hdr.bin
wget https://gitlab.com/kernel-firmware/linux-firmware/-/raw/20240410/mediatek/WIFI_RAM_CODE_MT7922_1.bin

for bin in WIFI_MT7922_patch_mcu_1_1_hdr.bin WIFI_RAM_CODE_MT7922_1.bin; do
	cat $bin | sudo tee /usr/lib/firmware/mediatek/$bin >/dev/null
done
popd

Results:

It connected once.
It remained connected or resumed connectivity across sleep and resume.
It connected again, after reboot!
It connected a third time after shutdown and startup. This seems like the fix. I will update the main tutorial.
It connected a fourth time after shutdown and startup.
I do need to note that it doesn't seem to be cleanly connected to the AP. It seems like it tries to auth many times, aborts auth citing by local choice (Reason: 3=DEAUTH_LEAVING), but eventually connects.

Failed to connect after machine sat idle for a bit and probably went to sleep. Here were the kernel messages:

This firmware + kernel does not fix the WiFi, BTW.
