Hi. I’m with BT and have the smart hub which is ok ish. Myself and my 2 sons all play PC games my current setup is the smart hub with port 1 going to a 1200mbps powerline to all 3 PCs. The download and upload is good but the ping (lag?) is inconsistent. Would I be better off going for a new modem/router or a separate modem and router to help with the lag? I have the original white modem from BT but unsure if all modems are equal? Please help. If I need anything my budget will be about £100 ish. Thanks
