I was playing battlefield 3 at my dads all day and my xbox worked fine. today i brought my xbox to my moms with me for the first time in a long time. I hook my xbox up and i play bf3 for 5-10 minutes and then i disconnect. i keep disconnecting every five to fifteen minutes. it makes me extremely mad because after bf3 starts to work after massive lag now i keep disconnecting. any help is appreciated.
