PoE is more reliable, anyways, if you're able to run it.
FYI Reolink has two PoE models, the white one and the black one. They are different. The black one has a wider horizontal field of view and no on-board package detection. The white one has a taller field of view and has on-board package detection. (Both do person and vehicle detection). In case that makes a difference to you!
I ran the Hubitat integration for quite some time. It definitely works. 275+ is a lot and a pain to move, although I will say after I finally bit the bullet and moved to dedicated antennas, both my Z-Wave and Zigbee networks have never been faster and more stable. Totally understand dragging your feet when they're all in Hubitat, but my guess is you'll want to ditch the Hubitat eventually.
I think what
Dennis said is accurate. The U.S. doesn't manufacture routers. Not really. Consumer ones, anyways. That doesn't bother me. I don't trust a large Chinese company any less than I trust a large U.S. company (or our government). Everyone collects data these days. If you're worried about a consumer router, then you might as well throw away your smartphone, too. And your computer.
I'm much more freaked out by GPS tracking and camera surveillance in public areas (projects like
Flock). If you live in a city, there are thousands of cameras owned by all sorts of entities tracking people wherever they go. But what are we supposed to do, never leave the house? I don't like it, but it's the world we're living in and I'm not losing sleep over it.
As far as WiFi goes, I prefer in my own home to keep everything that I can hardwired over ethernet. Mostly for performance and reliability, but also for less RF and interference. I just believe hardwired is simply better, if less convenient.
You could always go with a U.S.-owned company like Ubiquiti, but you'll be paying 3x-5x times the prices, and their products are still manufactured in Asia. Ubiquiti has very good products, I'm just saying there really is no 'perfect' option unless you want to go the completely open source firmware route, and that comes with DIY and technical know-how requirements. Too much hassle for too little reward for the average person, probably.
The last thing I'll add is, I wouldn't be concerned about any foreign-made router that's from a large company like TP-Link or others. Just my opinion, though.
Concrete is tough... like
Dennis said I would look at a "mesh" system. It's basically one router that acts as the primary (like your living room), and then you can add satellite routers elsewhere in your house. But they all kind of work together as one big router, without getting too technical. It's a game changer for large houses, or houses with certain materials that block RF signals.
