Internet in my area is really crap, luckily I live about 100 metres from an O2 4G antenna. I now have a 4G ‘hotspot’ acting as a modem and routed through a gaming router. Since going to that, my internet has improved massively. However, some days I can hit 5 Fell Cleaves as WAR and sometimes I can’t. It’s frustrating but I generally try little things like closing Steam down, disconnecting my phone from WiFi etc. Every little helps
