Things You'll Need
Instructions
Use an Ethernet cable rather than a wireless network for Internet access. An Ethernet cable will provide a stronger Internet signal to your PS3 than a wireless router. Wireless networks can go in and out and are vulnerable to signal interference.
Place the wireless router of your wireless network within close proximity to your PS3 system. Putting the router close to the system will strengthen your signal and help reduce lag due to dropped connection or signal weakness.
Do not use the Internet on other devices while playing your PS3. If other individuals in your home are using the computer or downloading files it can cause the Internet connection to slow down and cause lag to occur.
