When you play a game online with your PlayStation 3, information about your actions on screen is being broken up into chunks and sent back and forth to an online server. The rate at which this information is being sent and received is called a "ping." The lower your ping rate, the smoother your online experience will be. There are a few things you can do to lower your ping on the PS3.
Pay for a faster Internet connection with your Internet service provider. Internet service providers offer customers different choices or "tiers" based on connection speed. The higher the speed, the higher the cost. If you have serious problems with online games on your PlayStation 3, call your ISP and move up one "tier" to the next-fastest Internet connection speed available.
Connect your PlayStation 3 to a wired connection instead of a wireless one. Use an Ethernet cable to connect your PlayStation 3 to your router or modem. Though wireless connections may be more convenient, by their very nature a wireless connection will always be a little slower than a wired one. Switching to a wired connection will lower the ping on your PlayStation 3.
Shut down all other processes on your PlayStation 3 while playing games. If you're downloading content from the PlayStation Network or PlayStation Store, for example, either stop the download or wait until the download is finished before playing online games. Letting your PlayStation 3 dedicate all of its available bandwidth to online games will dramatically lower your ping.
