Please post the terminal output of
sudo lshw -C network
here to show us which driver is used.
You could try the solutions mentioned here:
A script that is launched after suspend or the commands
sudo modprobe -r mt7921e && sudo modprobe mt7921e
(you can test if they work after suspend to activate the wlan. If yes, add them to autostart - create a launcher with these commands.
Or add the kernel parameter
mem_sleep_default=deep
to file
/etc/default/grub
