I am on BT Infinity 2, I am using the stock BT openreach modem with a Netgear Nighthawk AC2300 R7000P.
Internet wise absolutely stable, WiFi is very decent for the price. The only issue with it is, BT TV can be intermittent at times due to IGMP Proxying which is a bit wierd on BT.
Im based in Bristol and this is my results for internet connection over ethernet via this method.
