any one know whats causing me to be dropped during matchmaking with friends, as soon as the map starts to load every one gets dropped from me and matchmaking restates

What do you have for an Internet connection?

i got frontier dsl. i have no problem playing a few weeks ago like week 2 or 3 of the championship, then i started back with reach and had no problems, now i when i try to go back to 4 i can’t play. i can play other game without much lag.
