So I've been eyeing the Asus BT10 router. Literally everywhere its sold in either a 1 or 2 pack but for some reason Best Buy seems to have a 3 pack which is on sale right now. Price wise the value of the 3 pack is a lot better than the 2 pack. I have a 3 story TH with ethernet ports on each level so I can do a wired backhaul for each level. I guess my question is would a 3 unit model even be worth it in a Townhouse?
