My iPhone 11 is at 14.2 and my 750S is at 3.14. I just tried the tether and its working fine as I type this using the tether.
I am blown away by the distances this little router throws a signal. I am sure my square footage in the house will support it. My concern is having 2 TV’s streaming 4K on 5ghz each wont swamp the throughput and start buffering.
