@Gantley You need to access tp link's page (http://tplinkmodem.net) & select "PC" before you login, then you'll see the advanced settings tab on the right.

@Warren569 I had the same reception issues with my Archer MR200.. I played around with the router's settings, until I found a solution, & the router's reception is MUCH BETTER. PS: this is for Telkom...
