5gee router with multiple devices issues

[Leonkenworthy]

Hello everyone! 

Recently (last few months) moved to the 5Gee router with external antenna because the copper lines to the property I live at are extremely poor. The village has had a 5g mast put up and just waiting for activation so I can have decent 5g connection. In the meantime I'm using 4g and to be fair the speeds are fantastic! But here's the issue. If I'm on the ps5 online and fancy watching something on my phone at the same time, my connection bombs out completely into un-useable land. Lag and all the fun stuff you definitely don't want. I've had home broadband routers for years on much much worse speed connections and been able to use multiple devices at the same time with no issues. I assume it's because it's a Mobile internet issue but maybe a router settings issue hopefully? Any advice? Please
