Roadrunner and 2 modems

It's impossible to use two modems on a broadband connection becasue you are only getting one IP Address.  Something else is the issue, probably a lack of sognal strength from the router to the X-Box.  Try moving the router to a more central location or get a repeater.

really vague idea but heres a suggestion..

i heard that routers come with plane-jane anetnnas, meaning they send the signal in all 360 degrees..even away from your comp/x-box. they make antenna's that send the signal directly to one another, so no information is lost due to it bouncing off of walls or going the wrong way..

3. Replace your router's antenna.

The antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your home, and much of your router's power will be wasted. Most routers don't allow you to increase the power output, but you can make better use of the power. Upgrade to a hi-gain antenna that focuses the wireless signals only one direction. You can aim the signal in the direction you need it most.
