I have been looking around and trying to research servers because I have been hosting online games via IP connection, that means opening certain ports in my network. The problem is my online game would become laggy after around 3 or 4 people joined, so this kind of made me angry when I wanted to play a game only with my friends with a certain game mode, ect.. (Game: Grays mod). So my question is, how could i fix this? would I have to upgrade my internet, buy a server, build a serve? Also I have a laptop laying around around going to no use, its a gateway laptop thats running vista thats decent exept the graphics card.
I would appreciate it if someone would help me and maybe give me a few pointers.
