Hello,
Having an issue that I have not seen before.
Game is crimecraft both me and wife play the game on seperate pc's at the same time, going through the 2820n router/adsl2,

If we both play at the same time doing missions we get horrible latency/desync, If she plays perfect same goes if I play.

Is there any settings on the router that I can tweak/change for this kind of issue (seems to me the games server is getting confused when we are both playing through the same IP)

Or is it purely a "contact the customer service for the game" situation.

Set yours and your wifes machine on a static ( Bind MAC ) then under NAT open following ports for both statics IP's

UDP: [29000 - 29999]
UDP: [7100 - 9999]
