Pocket wifi 4g constant drop outs

I have had a pocket wifi 4g for 2 months now and half way into my second month it has become impossible do do they following

Play any game in any device ie. Ps4 and laptop
Drops every minute or so i can play for 30 seconds then disconnects and reconnects 1 min later

I also cant stream anything ie. Netflix

All i can do is load web pages but sometimes even then the server will time out

My postcode is 6210 and i live in halls head
