This router is great, without additional external 4G LTE antennas it's boosted my speeds from 1Mbps on a TP-Link to 65Mbps. The only thing I don't like is the Armour Protection (which can be switched off) this prevented my chromecast and sonos from working. But overall would recommend. Would be nice if there were clear directions on which rf connectors are used to connect external 4G/LTE antennas.
