[SOLVED] Question about coax jacks!!!

[SimonD1106]

I've moved to a 3-story house recently. I put my computer on the 3rd floor, the modem is on the 1st floor. I found one coax jack on a wall on the 3rd floor, how can I use it to get wired internet for my computer? Is it possible? Thanks for your help!!!

Moca is a possibility. You will need to know where that cable goes though.
