Serious? Netgear make some great routers. Personally, I'd say that Netgear and Cisco make probably the best machines available. Certainly in the consumer market. Everything I've ever experienced from Belkin has been a flaky POS. In fact each and every time a friend or colleague mentions a wireless networking issue, they always turn out to own something from Belkin.
OP, try using a fixed IP for your devices that have issues. This could well be a DHCP server issue. In my experience, poor quality routers seem to crap-out in this regard after about 364 days of ownership.
