I use a dongle for internet at home (as the Girlfriend doesnt want to be tided down to a years contract at this point because of the baby and money and so on)
So we have to make due with a T-Mobile dongle, which ins't bad as they have a fair useage which means once our money we put in goes we can still use it to surf internet for free ( that also includes using the xbox)
I've not had much trouble with it, I'm managed to play Gears with Publik and Ninja and a few other with no problems just the odd kicking me off line but not that offen, but just lately (well this week infact)
I've not been able to sign on to xbox live at all, no matter how any times I turn xbox,laptop, dongle off it still won't work, I've done a test connectiong and it all goes thought then when it gets to the last stage it says there is a problem with internet connecting to xbox live, just wondering if any of you use a dongle or know why this has started to happen?
