Connection Problems [Please Answer if you know one]

Ok so I have been having problems ever since I joined the xbox community, I have 60 friends in which none I can connect to, But when Im on BF3 I can connect to them, So I went into my ISP on 12/14/12 and complained about this situation, and he said "Microsoft's
servers can only handle a small ammount of connections and the other ones get thrown out, So you can connect to someone across country but not next door." I am starting to believe this because I have Fiber Optic connection, Running at almost 100mbps, and
I cant connect to any one on the same ISP or in the same state I live in.

So I do need some help and dont say "Get a different ISP because its not that at all" or " Get a new router" because my router is over powered. But please help if you can,

Thanks

This post really helped me whn I got my new router. In my case, I had to shut off the additional firewall in the router and enable UPnP (universal plug and play).
