Probably a typu. Whatever, I had setup a passphrase that was the first

From my experience, yes.

As in cooking microwaves? If its leaking that badly, have it serviced by
someone with a leakage measuring apparatus. Or replace it. That level of
leakage is sick bird on this side of the pond. I've checked and
rechecked the $100, 1kw model I got from wallies to take on the road
when I was out doing consultancy things after I retired for a few years,
in my kitchen now and can't find it with that meter. 15+ years old now,
I've had to replace some of the interlock microswitches, but 30 seconds
for a cuppa is still too hot. Sagging doors are the usual suspects.
Here we have to leak test our broadcast transmitters and be able to
certify they have a leakage field that is less than 5 milliwatts per CC
of human flesh exposed or we cannot renew our license. Thats actually
an easily detected level but must be measured with an omni-directional
antenna. Only one such device is available, and they rent it to us at
$275/day.
Yeah, I'm actually a retired broadcast engineer. What used to be a 1st
phone, and CET cards in my card case. ;-)
I recall having to send the meter on to another tv station about 110
miles south of us after I'd logged the measurements from our 50+ yo 35KW
GE box, and he was curious and had it running when he walked into the
stations lunch room while someone was warming their dinner, and it
pegged the meter while still 6 feet away. Needless to say, the vending
company it belonged to was onsite in about an hour with a new one, which
had zero leakage.

Construction materials generally make good dummy loads at 5GHz. :)
Drywall and rock rubble walls seem to absorb it well. One friend of
mine on the left coast lives in a 300 yo Spanish Hacienda that covers
most of a city block, with interior stone walls a couple feet thick has
had to wear out some diamond bits getting cat5 here and there. So yes,
I'd expect you'll need repeaters.
