I think people's experience with PLE will always be subjective. In the old flat we were in, where I needed it. It would drop connection all the time, it was unusable.
But I've had them run totally fine in other places. Noisy power supplies that aren't even in your place can cause problems. Any kind of impulse noise (bad contacts on an old style thermostat for example) and all kinds of other things can and will interfere with it.
Wifi is always a compromise too. But, I guess if wiring direct is not an option, the OP needs to choose their compromise.
Pretty sure mine was 16399753. But, not logged in for probably 15 or more years, so could be wrong.
No idea whatsoever about the password :P
