Currently I have an Amplifi HD as my router. It handles the wireless needs of our upstairs and DHCP for the entire house. I have a hard wired connection from it to a 5 port switch in my family room. One of the ports on the switch feeds my downstairs AP, a D-Link DIR-842. This handles wireless for the downstairs although the 2 units do mix in some areas of the house. Downstairs we are running into a lot of connectivity issues. Random drops on mobile devices occur frequently as well as slow speeds and sometimes no internet despite the fact that my TV is streaming just fine directly from the same switch. So I'm looking for some advice for a new AP. When I bought the Amplifi HD about 18 months ago I had it in my head that if my other AP didn't perform well then I would pick up one of the Amplifi Mesh Points. Well the meshpoints have been out of stock for a while now and there is no telling when they might be back in stock. Sure I can pick one up from Amazon for twice the actual retail price, but that's not happening. Any other units that will work with the Amplifi HD or do I just need to stick with a router configured as an AP still?
