To check go to the internet connection settings and run a connection test. Just wondering as it shows type B for me and I wonder if the NAT type has any effect on online, as there isn't really any explanation of what the different types mean. If you have played online please reply with your NAT type and your online experience (any connection problems?) Personally I've played online in Bomberman and Fast RMX and both seem to work fine (Type B) although I have had lag issues in certain matches in Bomberman which completely ruin the game, as my character doesn't respond to my input in a timely manner so it might take seconds from when I try to turn or drop a bomb until it actually responds. That's probably a connection problem with one of the other players, though.
