I got problems connecting PS3 to Internet the other day. There kept popping up error message on my screen when connecting. However, my laptop can get access to internet very well through the same router. Fortunately, after some time-consuming research, I find the way to fix this PS3 internet connection problem. Here is what I did...

Firstly, update my wireless router. As you may know that routers driver software need to be upgraded periodically in order to function at their best. Make sure that it is updated to the lasted version to avoid any possible disturb.

Secondly, change the SSID and WEP password. SSID (Service Set Identifier) is the name of your wireless network. You may discover different wireless network listed there, choose your own one. Remember to lower the security if you use WEP Encryption because high security may cause PS3 internet problem. And add your PS3 as an accepted device if you WAPs are set to filter MAC address.

Thirdly, go to Internet Connection Settings. PS3 internet connection problems are often solved by changing the network settings. Follow the steps listed below:

a) Change your DNS server address to the OpenDNS servers: 208. 67. 222. 222, and make sure your PS3 settings are on automatic/easy.
b) Locate the IP address of your router.
c) Open a web browser (Firefox that is what I use) on a computer connected to your router (For the PS3's browser didn't work you have to use a computer).
d) Manually type in the IP address of you router into the address bar.
e) Ensure to enter the correct username and password you ever set if asked. If you never set one, you need to enter the default username and password. You can found them on the manual of your router. Try username "admin" with no password in case you can't get any information there.du home wifi packages But there is only a little chance you can get through.
f) Once you get in, enter manually "DNS Primary and Secondary". Enter DNS address 208. 67. 222. 222 as primary and 208. 67. 220. 220 as secondary.
g) Check and see if PS3 Internet connection problem still exist.

Hope they are helpful.
