AT&T Fiber... I Finally have good speed

I sure was glad giving it the same network name allowed all previous devices to connect automatically. We have two dozen bulbs, six cameras and countless other devices attached. Now I’m eyeing a weatherproof mesh unit for the backyard and my wifi heart will be content.

next question. When a router says connect up to 60 devices, does it mean there are only that many IP addresses to give out (or other hard restrictions) or is that just based on average bandwidth consumptio?
