Thanks a lot Vivian. I came across some 3G/4G amplifier ( https://www.youtube.com/watch?v=cr8Yw5Tj-UA) but wonder if this works with this model.

Model : Hardware Version : Not Clear Firmware Version : ISP : Hi team, I was wondering how do I boost the signal of Archer MR200, is there any external 3G antenna to boost the signal or any other...
