m live isnt working and i plug my ethernet cable into both my router and xb but when i normall plug it in it the ethernet light on the router goes on but now it doesnt any tips?

Just yell at it , jeez people and their problems.

If yelling doesnt work check to see if the ethernet cable is to blame and connect it to your pc. If it works there and not on the 360 the only thing the J man has to say to you is to send it back to MS. If your 1 year warrenty is done and your not willing to spend money on the repairs just yelling at you 360 will make it all better :)

Is there something wrong with your "Y" button on your keyboard?

Have you ran the connection test? What error does it give you.

says cant find network

try a different cable

try connecting right from the modem to the xbox
