although my personal preference, when it comes to wireless router/modem combinations is for the Netgear wireless cable/DSL router.
I've installed several for clients, and each time they've worked perfectly, first time, and have continued to do so. It's just my preference though, and I'm sure you'll be pleased with the Belkin model - the company makes superb products.
I use the Belkin USB adapter on my own network - they're trouble-free, and set up is easy. Install the software before connecting the adapter though.
