How to Fix Network Problems on Call of Duty 3 on the PS3

"Call of Duty 3" is a military game developed by Treyarch and released in 2006. The game requires you to work through a range of single-player and online missions. Multi-player games involve you competing against other players in a 24-player battle. If the PlayStation Network on your PS3 is set to moderate or strict, it can be difficult for you to connect to an online game. There are also settings you can change on your router to improve network performance.
