Well To start of my xbox works perfect on my dads internet. Which is with bt broadband. But when i connect to my girlfriends internet which is with orange it keeps kicking me off line. Seems to be more with fast acting games like black ops or modern warfare3. The orange broadband speed is averaging at 3.5Mbps to 4.5Mbps which should be more than enough. Im connected hardwired and ive called orange for the help but they say the line is fine. please help me. its driving me mad.
