5G so slow?

Is anyone else with Three and really struggling with 5G recently? Used to be fine but last couple of weeks it’s been so slow I can’t load anything at all. Our WiFi is a Three 5G broadband hub as well and also isn’t working!

EDIT: after reaching the depths of 0.9MBPS download speed I called and managed to cancel my contract with Three for free. I’m now with Virgin and enjoying 250MBPS! Would recommend switching for anyone struggling atm!
