Hello, I bougth a MAX HD4 LTE on september 2018. One months ago I bougth a MAX ADAPTER 5G. The actual firmware is 8.3.0. The connection is ok and I am watching 5G, but when a did Internet Test I got 7 Mbps (download/upload). I did a test using a same sim on a China Unicom 5G router and I get 54/35 Mbps. I did another test connecting MAX ADAPTER 5G directly to USB 2.0 on my Notebook and I get 309/83 Mbps (really good). Any idea? May be the USB or I need to install an older firmware? Or some configuration?
Thanks in advance
