I have a horrible geographic location. Using T-mobile in a 4glte router. Just bought a 2 x 2 mimo antenna from Waveform. Speedtest.net shows less than 1.39 mb download, 1.17 upload. Yet I'm able to stream Youtube at 720 resolution without issues, while my wife uses LINE to make a video call to Thailand. It's hard for me to believe these test results are accurate.
