I normally run 3/4 xboxs (xboxes?) off of my interent connection at my apartment for XboxLive. At first I never experienced any lag, now my friends and myself lag constantly, I contacted the ISP and they told me that my modem might be going bad. I pay for a 4.0 megabit/sec cable connection, and i normally clock in about 3.5 running through a linksys router, am I lagging because of too many xboxs on one connection? I am willing to buy a new modem if that is the case, just curious what you guys would recommend as far as a good one. Thanks for your help.
