I pay for 600mbps internet and when hardwired to my ISP modem/router and the main deco, the speed is pretty accurate and when I'm on wireless near the main deco, the speed is pretty good. However, when I move to the upstairs, the speed is dropping on the satellite when connected to it wirelessly. I'm only getting around 60-70mbps. Looking at the app, the satellite only shows 133kbps. Is there anything I can do to optimize this?
