I'm trying to connect to Xbox Live and have reached the end of my rope trying to figure out what to try next. I am using a wired connection and have the XBox hooked right up to the router (RCA Thomson). I keep getting an error message that the MTU isn't high enough but when I check it shows that it's set to 1500. I've tried unplugging and plugging everything back in, restarting, etc., with no luck. Once it started connecting to XBox Live, got halfway there, then there was an error (not the MTU one) and it stopped, I have not been able to get that far again. Would it make any difference if I got the wifi adapter or would I run into the same problem? I really don't want to spend the money as I only want the connection to finish a specific game but I am starting to get frustrated. I have Time Warner Cable broadband (if that makes a difference) and the XBox is the only ethernet cable plugged in (everything else is wireless). Anyone have any idea what else I can try or is it a loss cause? Thanks!
