am i missing something here are the "Ariel's" on the tp link routers for puting wi-fi out or picking up 4g signal ,i think they are for distributing the wi-fi and cannot see where to put the external ariel to improve the incoming 4g
I don’t think so. This suggests that the antennae are for the 4G, not the WiFi https://www.tp-link.com/uk/home-networking/3g-4g-router/archer-mr200/#specifications
