I recently bought an Xbox360, so I bought a Linksys wired router to share my DSL connection with my iMac and Xbox. I figured I could connect the modem to the Linksys... connect my Airport to Linksys port 1 and the Xbox to Linksys port 2 and that should do it. The problem is, only one device can connect online at a time. When I'm on the iMac, the Xbox won't connect. When I'm on Xbox LIVE, my iMac's Airport icon will read "looking for PPPoE." Anyone know what I might need to do to fix the problem? Do I need to adjust my Airport settings?
