Is the PSN down??

^^^^????

no not at all

stop bumping.. and no it's not

no but i do have connection problems with PSN sometimes

Here is the message of the dude that helped me:

"I was having the same problem earlier.

Here's a fix that worked for me:

- Go to Network Settings on your PS3 and select "Internet Connection Settings".

- Select "Custom" and then select Wireless or Wired depending of which type of connection you have; I selected Wireless.

- On WLAN Settings select "Enter Manually" and then enter your SSID and WEP/WPA (If you have one) this should be on the back of your router.

- Once you have entered your SSID and WEP/WPA select "Automatic" on IP Address Setting and on DHCP host name select "Do Not Set".

- Now this is the most important part, on DNS Setting select "Manual", then type the following settings:

Primary DNS: 4.2.2.2
Secondary DNS: 4.2.2.3

- After you have entered that info leave the MTU on Automatic if you like, I selected Manual and left it on 1500 but there really shouldn't be a difference.

- Proxy Server select "Do Not Use"; UPnP select "Enable".

Confirm those settings and test your connection, If you selected everything correctly you should be done with the DNS error and hopefully you'll be getting a NAT Type 2 connection.

If you do get NAT Type 2, from time to time It may switch back to NAT Type 3, when that happens I just turn off my PS3, reset my router, let it connect again and it should be back to Type 2, at least that's what works for me.

Hope this helps you getting rid of the annoying DNS error and getting the best connection out of your PS3."
