The 2862ac is probably a good place to start. I use a 2925 with a 130 as a vdsl modem, and then a couple AP910c's for additional wifi around the house. If you are thinking you need separate wifi units, then you could just go for the 2862 and add in a few draytek APs which can be managed from the 2862.
