ive moved my 360 to another building with a new internet connection, ive used this connection before to connect to xbox live but for some reason its not letting me connect again. im using a ICS connection and have used the same setup before. it fails on the IP section, the PC can pick the 360 up but the 360 wont see the PC.

my PS3 also cant connect to the PC, so ive put it down as a PC or network cable problem

Your firewall could be blocking them from coming through.

ive already tried disabling it but it dosent work

f i network the PC with another PC it will work fine, if i take out the network cable from the second PC and put it into my 360 it will work for about 2 minutes then disconnect, i then have to start the entire process again.

 

 

 

 

 

this problem has really got me confused, i dont have a clue what could be causing it

Are you plugging from the modem into the 360? If so, disconnect the modem from the 360, shut the modem off, wait 30 seconds, plug the power cord back in, wait another 30 seconds, power up xbox, then plug in modem to xbox.

 

 

 

That might work, if not call your ISP and tell them to re-set the modem.
