Here are journalctl logs from two different systems where wifi was not available at boot
This should probably go to the Linux repo if those drivers are part of the kernel
I don't think the MediaTek drivers are part of the kernel itself, but rather, they are part of the separately distributed linux-firmware
package: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/LICENCE.mediatek
I think this issue describes the same problem as mentioned here: https://github.com/pop-os/pop/issues/530#issuecomment-1614732241
At least two other people have reported issues with the MediaTek MT7921/MT7922 Wi-Fi devices in that issue, and other than Wi-Fi sometimes being unavailable on boot, there seems to be a related issue where the laptop also hangs during shutdown whenever the Wi-Fi is unavailable. If you are having only the Wi-Fi issue, but not the "hang during shutdown" issue, maybe the MT7921E that you have behaves slightly differently than the MT7921 and MT7922.
Either way, MediaTek have submitted several patches for these 3 Wi-Fi devices during the past months, so I'm hoping that pop-os/linux-firmware#35 will have fixed the issue. I think all that's left before we can try the 20230629
version of linux-firmware
is a release here: https://github.com/pop-os/repo-release
EDIT: The new version of linux-firmware
is now available in the Pop!_OS APT repository, let's try it and hope that it fixes the issue.

I think this issue can be closed for now. In my case I did not have this problem since the update (this is not a very long time, but still). How about you @jacobktm ?
In case if this is not fixed it could be reopened

):The issue is related to the mt7921e Wi-Fi driver, which is part of the kernel.
Issue/Bug Description:
Sporadically, during system boot, Wi-Fi is unavailable, and no networks can be detected or connected to. This issue does not occur on every boot, but it happens occasionally. A reboot or system suspension resolves the problem, and Wi-Fi becomes available again.
Steps to reproduce (if you know):
Expected behavior:
Wi-Fi should be consistently available and functional during every system boot without requiring a reboot or suspension to resolve the issue.
Other Notes:
I have seen this behavior on several systems with a MediaTek wireless adapter, including pang12, mira-r3, and major-r4. The Wi-Fi driver in question is the mt7921e driver, which is part of the kernel. I have also seen this issue in both Pop!_OS 22.04 and Ubuntu 22.04 with the Pop PPA and kernel installed.
