It seems that I'm unable to get a ping rating from about 25% of the users online. I'm assuming this is because my opponent can't get my router's ping rating. I tried unenabling the "block ping" option on my router settings, but no change.

If I unintentionally disconnect with an opponent, am I awarded a loss? If I quit during the game, am I awarded both a loss and a disconnect? If somebody challenges me, and my connection craps out, am I the one who gets the demerit?

Basically I want to take every precaution possible to avoid disconnections and the like.
