Product description from Newegg.com:

You just got your high speed modem (it could be cable, DSL, fiber optics . . . something nifty), and you’ve got your computers, and you’ve got your wireless interface cards. Now you need the final element: the router. With four wired ports and the wireless connectio
n, you’re ready to take on the Internet and all it has to offer. Or maybe you just need a local network off the ‘Net for your small office. Maybe you’ll hook your desktop up by cable, and carry your wireless laptop to your favorite seat. Control and configuration are easy with browsers like Internet Explorer 8 or Firefox 3.0.

We’ll be here, cheerfully waiting while you make up your mind.
