So I can only summise that there is something in the AP setup that causes some strange DNS behaviour over a few days before it all stops working and clearly the wired network is fine. As the only difference is that my daughters PC is connected to the U6-LR and my sons is directly to a Gen 2 24 port POE (unifi) that it must be the AP.
We need to isolate where is issue is. I get what you're saying that it's only clients connected to the AP that are affected but that AP is connected by a cable to a switch port. If there's a problem with either of those then only wirelessly connected clients will be affected but that doesn't necessarily mean that the AP is to blame.
When the problem is there, can the problematic devices ping things on the internal network? Try to ping the UDMP. Can they ping things on the internet by IP? Try to ping 8.8.8.8.
Hence why I asked if you can ping things on the internal network.
