Call of duty 6 server problem

waiting a long time for the match making process to find a server is normal.
the default is a disaster.
i would suggest using alter iwnet .. but i used it and my game will suddenly close while playing.
it just disappears into thin air apparently.
with that said, i think maybe there is a security problem using the alteriwnet version.

i find that to be a real disappointment because alteriwnet circumvents the constant playing of the same two or three maps that iw match making forces upon its players.

when i used the default iwnet.. i would be stuck playing the same two or three maps for more than 1 hour.
lack of map rotation is really obnoxious and problematic when the maps i am stuck playing are not the ones i want to play.

with alteriwnet, you can pick which map you want to play because you can pick a server that has the map you want currently running.

it really stinks because i prefer modern warefare 2 over black ops any day.
