Netflix nw-2-5 error using AP6 and AP6Pro

I have a strange problem when trying to stream Netflix, Hulu, Max on both Google and FireTV devices, where they are not streaming, or connecting at all. Netflix gives a NW-2-5 error which points to slow networking speeds, but the speed is there. Finally I connected a TPlink AP and it works great.

What setting or change do I need to make to get these Alta APs to work with basic streaming. BTW YouTube and all other streaming services work fine.

I changed the security to wpk3 from wpk2 and that didn’t help either.

Thanks for any help.
