Wireless manufacturers do vary slightly in their individual implementation of wireless standards, so if you want a hassle free experience, I would stay with Belkin.
Just buy a Wireless Router that supports your wireless protocol (whichever that is) and a USB connection for the modem.
You will then plug the modem into your new router and each computer will access each other and the Internet via the router. Make sure it also supports the latest security protocols, as security via wireless is an issue.
