Yeah ive heard alot of people blame various things such as mesh but im not convinced, I had the exact some issue on two different 1st Gen 4K ATV's....the only way around it is to use the ethernet, plug in a wifi extender near the ATV or something and run an ethernet between the two, thats how I fixed it.
Dude - we’ve fired up a thread from 2019!

I signed up to just be able to comment on this problem, I've worked around it but I can confirm that both 1st Gen 4K ATV's that I own do the exact weird WIFI thing that has been repeatedly reporting on this thread.

I have a 3rg Gen 4K ATV but thats always been Ethernet, slightly sore that I had to pay more for the ethernet port, thats crazy! But im not unplugging it to test :/
