Over the past three weeks, I have been lagging on every game i play. I have a smart hub, the xbox is on 2.4 GHz and we cant change it to 5. We have spoken to Bt four times, they have changed the channels from 1 on 2.4 to 6 and 36 on 5 to 44. This hasn't helped my latency problems at all or solved my issue. When the download speed is 25 mbps the latency is fine but when it drops down to 1-5 mbps the latency goes up to 1300m/s which obviously is really bad. Can anyone help?
