This reminds me, I'm probably gonna need a new router. Where's the best thread for that (buying a new one, not fixing my old one)?
I just got a Netgear Orbi for cheap on ebay, but it sounds like you're wanting a modem/router combo, right?
The mesh stuff is all the rage these days. They are all fine if you can't run cable to every AP and you realize that every hop from the main router cuts BW in half and raises latency.
Orbi is a bit different with a dedicated backend frequency so bandwidth does not decrease. It's also AC3000 speed. I'm getting 230 mbps on wireless, out of my 250 mbps service.
Even then, I only have the one router and it does a great job. I went with mesh because I'll probably be moving in the next year or so and wanted to be able to add a satellite if I needed.
