I live out in the country with bad connection to Xbox Live Help Plz!!!!!?

I live in Arkansas with Wild Blue as my internet provider. I have a Linksys Wireless-G Broadband Router w/ Speed Booster. I can try to play a match on games such as madden 11, and i'll get right to the kickoff and then it says i lost connection to my peer. I have both a wired and wireless adapter but it doesn't seem to help if anyone could help me I would be extremely grateful.
