Go to http://www.dd-wrt.com/site/index, flash your D-Link router with their firmware and you can turn it into a wireless access point, basically a wireless adapter with four ports. Then just match up the wireless settings, and connect the D-Link to your Xbox with an ethernet cord, as long as you have wireless signal you'll be online. Just go read up on it.
I can guarantee it works because it's the exact same thing I'm doing with my computer/xbox, except I'm using a Linksys router. Like I said, it turns the router into a wireless adapter with four ports.
Edit.
I looked up the compatibility of your router, couldn't find it on the dd-wrt supported list, so this might not help you at all.
