For gaming you really want to look at wired networking over wireless networking.
Wireless performance can be very hit and miss even with better quality routers depending on individual circumstances.
Which router depends upon price range and additional required features.
If all you are after is good wired
gaming and wireless connectivity you should be ok with most wireless routers.
Generally I would avoid belkin kit and would recommend netgear for most people. For more in-depth requirements, and if you can justify the cost I would recommend draytek routers.
If you still wish to use wireless for gaming then I would advise you to look at the higher spec 802.11n wireless routers, particularly routers with 2 transmit and 2 receive paths or more.
Again I stand by the advise to avoid belkin, and recommendation of netgear, and draytek if you can justify the cost.
Alas my experience of other brands is limited, and so would suggest waiting for other recommendations.
