Isn't it great to challenge your friends on the network but equally frustrating when you cannot connect to the internet even after a million attempts? You are now faced with a situation of a DNS error on your PS3 but you don't need to worry as it's not a sign of a hardware failure so don't feel that your PS3 has died.
A DNS error is caused by a wrong configuration, ISP downtime or a faulty router/modem. So in order to rectify this, you have to examine the connections to your network and the actual settings within your router.
Be it a laptop, desktop computer or a console, a broken web connection or faulty wiring can interfere with connecting to the internet. The PlayStation 3 is among the most advanced consoles in the industry. Nevertheless, it does suffer from system issues like other machines such as DNS errors.
Here are 5 good tips to get you underway on solving that DNS problem
1) Reset the Modem
You should turn off the power of the modem for several minutes and then restart the modem to see if the problem has resolved by going online with your console.
2) Turn Off the Computer Firewall
If your modem and router are connected to your computer and it has a firewall, it can be the reason for your PS3 DNS error.
3) Verify the Configuration Settings
You should check the IP address entered on the PS3 online connection screen and ensure both the primary and secondary addresses have not been entered in reverse order. If this has happened then change them and reset the console before reconnecting back to the internet. You should also check if the correct WEP key and SSID of the wireless network are entered into the PS3 configuration screen, when these values are entered incorrectly, a PS3 error occurs.
4) Upgrade the Firmware, Check for Software Updates
You need to check the PlayStation website for any new software upgrades. If there are any, download them, install on the PS3, and try reconnecting your PS3 to the internet.
5) Try a Wired Connection
Setup a wired connection by connecting an Ethernet cable from the router or internet modem to see if the DNS error is corrected. If this works, then your wireless router has a problem and it needs to be replaced so that your PS3 works on a wireless connection.
So get on with fixing your PS3 DNS errors so that you can start playing your online games and enjoy the ultimate gaming experience
