been looking at Night hawks and other routerrs Iv got a bt hub 6 just now but its not coping very well what router should I buy I'm not worried about wifi only the hard wired lan is what I want can I gain more speed for online gaming I know nothing about networking its just not my bag so would I go for an Asus Mu Mimo thingy or the night hawk ones or just stick with the hub 6 and buy a big bag of sweatys?
