See here is the thing. Me and some friends have been trying to play a pc game which requires us to open ports to connect to each other. To do this I need to disable my firewall and do disable my firewall I need the user name and password which was lost years ago, not my fault wasn't responsible for it. Basically what I want to know is if I was to buy a new router would it be able to use the same internet without any trouble and have a new user name and password which I could keep safe and use to access the firewall?
