Sigh, I was just asking if i need a modem or a router or both for the best experience in gaming but i guess i didn't know about the Dsl and all this stuff. All I know is when I get better wifi I am connecting it to my computer and there.
A modem or router is not what you need.
Do some research into powerline devices.
This is a pair of devices that will provide a mostly wired connection to your router. The singal is pumped through te house wiring.
One device plugs into the wall next to the house router. A short ethernet cable from the router to this powerline device.
At the other end, where your PC is...the other powerline device is plugged into the wall, and a short ethernet cable from that to your PC.
Something like this...
