Have you tried using only the 6100, without the Belkin router. How well does it work then (for your gaming activities).
If you have not tried that, please give it a try. It will help to determine whether your problems are with the 6100 or with the Belkin router. -- AT&T dsl; Westell 327w modem/router; openSuSE 11.0; firefox 3.0.10
