I'm a real newbie when it comes to computers, internet, networking, etc. but I'm an avid gamer. And I play a game (on my PS3) which plays best at a higher pings (slower speeds) for some reason beyond my understanding. So after a LOT of searching I've found how to access my router settings: I found my 'Default Gateway IP-thing and typed it into my URL bar and entered my router password. ...this is as far as I've gotten.
From here, I just want to make only ONE of my 4 ports have a high ping (slow speed) so I can plug my ethernet cord from my PS3 to that port when I'm playing that specific game. I don't want to tone-down or negatively effect any other port or slow the speed of anything using the WiFi... only this one port.
How do I go about doing this... in layman's terms?
