X-Box Live Connection?

you should get a new wireless connector that hooks up from your 360 to your router and make sure no ones messing with the router ---if they accidentally drop the router it could mess up both the router and the connector ---some times you need to reset the router {reset button in the back -needs to be pressed with a pen} or u unplug the router from the outlet in the wall for exactly 10 seconds , count 1 Mississippi 2 Mississippi...... until u reach 10 Mississippi but some times i count a little more just in case and when your done counting plug it back in wait for all the lights to come on--let should come on 1 at a time so wait a while, when there all blinking at the same time but not in the same way go back to your 360 and press the xbox guide button {middle green x button} and go to connect to xbox live---it should work but if it doesnt go 2 test connection there might be something else wrong with it -- ive had problems with my connection before and what i just told you to do i did and it worked after that or also the wireless connector you have now or any kind of connector you have now is probably not plugged in all the way{in the router or your in the back of xbox} and thats all the info i have for you i hope this helps
