I would recommend a dual-band wireless-N router. Something like the Linksys/Cisco WRT600N. The dual-band will work very very well for multimedia streaming applications (eg. HD-video). I've found Linksys routers to be rock solid (and like you have had a crappy experience with a Belkin router). The WRT600N has built-in support for QoS, and is also compatible with alternative open-source Linux-based firmware such as DD-WRT -- should you need to extend the capabilities of the router in the future.

For the record, I purchased and installed a D-Link DIR-655 wireless n router this afternoon, and the packet loss is now down to 0.0%... here's the test I just ran:

Packets out of order: 0.0 %
Estimated MOS score: 4.1

On Comcast HSI the evening speeds are much slower downloading than other times of the day, and now I'm happy that the call quality should go up. Now to unload the old router...
