Return to Castle Wolfenstein Servers Problems

I bought the Return to Castle Wolfenstein and when I try to play online I only have a list of maybe 20 servers to connect to. My friend on a different cable system has hundreds. With only 20 most are full, some won’t let me connect at all. So usually I only get to play late after most people are in bed.
Any help as to why I can not connect to many many servers like he can.
