>> Repeaters add latency and I can't imagine any network engineer would ever recommend one.

Keep in mind that these TP-Links are consumer grade hardware, and that they make sense for some use cases. Not every consumer can or wants to run wire for another AP, regardless of what a network expert would say.

I use an RE450 at my dad's house (which happens to be next to mine) so when I'm there I can access the Internet. My parents don't have any computers, smartphones or tablets and don't use the Internet. The RE450 does the job -- very well I might add -- and was cheaper and easier than drilling holes in masonry to run a network wire between the houses.

The NTP and DNS requests are concerning, but they don't materially impact my bandwidth cap on the plan I'm on.
