I have been getting the error code 80710723 on my ps3 and know the codes that I need to put into my routers firewall but where is the fire wall that I am looking for? My router has a screen and if I click on it and then go to wireless security it wont let me click on it? Is the router firewall on the computer? It is a belkin if that helps (router) thanks for any help....I REALLY NEED IT!
