I have a couple of different modem/routers for gaming specifically. In short I'm in search of the best possible connection. The best connection so far as been draytek 130 modem in the 5364's wan. Zero errors, stable line with good snr. Talktalks has errors and my upstream and is -15.
Given your earlier comments regarding your 130/5364 combo I'm not sure why you want to change. However given you do it might be worth look at routers targeted at specifically at gamers by manufacturers such as ASUS, TP-LINK, and Netgear and/or doing a search for "best gaming routers" .
I use, and am very satisfied with, a Draytek 2762 but that is because of the facilities it offers rather than for gaming purposes.
