So, how do I find the GWN7630?
I'm quite happy with the GWN7630(s) - quite responsive and what I like the most is it's mesh management capability including the GWN7610 as well. As before there is no need for any external controller for configuration or operation - the master AP is doing the job for all slave APs (config, updates, ...). If you are a cloud fan boy, there are some (additional) sophisticated funtionalities in a cloud as well (i.e. site survey, coverage hole detection and other statistical gimmicks) I don't care about because of my own security rules.
So with simple words: an even more powerful next step AP after the already very good and robust GWN7610 which I had/have in operation with 3 VLANs (private, guest, IoT) since 2017 without any flaws. A colleague of mine was a little bit disappointed about the endless GWN7000/GWN7610 router integration time but that's solved since a few weeks and he's happy again. The prices of the GWN7610 might come down further since the GWN7630 takes it's position.
You can't do anything wrong buying a GWN7630 from my point of view and I assume it's capabilities between UniFi nanoHD and UniFi AP HD at a lower price. In my opinion even the GWN7610 could be sufficient for most single AP users (with a single AP only, mesh makes not much sense and not everybody needs the internal IPv6 addressing capability and the higher bandwith more depending of the clients).
Asking me the reason for migrating away from EdgeRouters or not finally jumping on the
UBNT train is, what direction they want to take as a company. They ignored some of the
most upvoted/requested ideas on their forum to pursue new products. "Best" for the rest
was the great idea just to remove the customer's upvotes/requests from the "new forum."
