I am using GL-MT300N-V2 with 18.06.2 currently, and my router often shuts wireless down after large traffic (e.g. watching videos or downloading for a long time). However, the network switch works just fine, and I can SSH to the router to check logs. I have to reboot the router or wait for a long time (several hours) to get wireless back online.
Actually, I do not think this problem is specific to my device as I have met the same problem on several other devices (TL-WR703N and TL-WR841N). And I have seen some posts complaining about similar problems.
