How do i reset my ps3 internet connection, just changed internet companys and ps3 wont work

Hello
Get the name of your router manufacturer and find out how to log in using a pc and the internet.
Or you can go on your pc and go to start run and type cmd.Then hit enter.

A box will pop up.Type ipconfig then hit enter.The ip address should be listed there.Something like 192.168.1.0
Type that number in your browser and log into your router.Username should be admin and password should be either the word password or admin.Again check with the router manufacturer.

Once you log om to the router make sure upnp is checked off and also get your wma or wep key and enter it into your ps3.
Once done restart ps3 and you should be connected.
