Alldocube iplay70 mini ultra WiFi dropout

As the title suggests, I’m really struggling with WiFi dropout. Which in the middle of online games is a massive issue. The counter on the top right of the display (which I’m assuming is showing connection speed? 0B/s for example) keeps jumping from high numbers. Down to 0B/sand it’s as fast as every other second. Even though the connection speed is saying excellent. And no other device in the House has the same issue
