I was using a Plusnet hub 2 originally with a Full fibre package (900mbps) but i wasnt happy with the speed it gave out on wifi connection was only around 80 , so i bought this router now i get a much better speed around 200-450 but i get really laggy game experiences and my latency is way more than it was and im finding it hard to understand what the problem is now surely the Plusnet standard hub wont provide a lower ping than this router 

i havent got a 6Ghz card yet but ill get one soon currently using a mercusys wifi 6 card dual band
