Is what I am using and it works right away. Can you confirm if it is stoping you from downloading or just downloading very slow.

I can confirm that on my system everything is downloading as bz2 files and I am able to connect from a fresh install in 2min.

I tired to clear out old cach data in the server to see if that helps. Also the data is not downloaded from the game server so what that speed was is the actual game data connection not a map dl.
