Moving computer to another room

[jomama]

I am needing to move my computer from one room to another.  Currently, in the kitchen   My internet comes thru kitchen wall.  I have the coax end in the room I am moving to.  Need to connect additional piece of coax to it.  How do I do that?  What is involved?  Am I explaining this right?  Does it make sense?

I have the coax end in the room I am moving to.

In other words, you have a coax connector on a wall in the room.  Is that right?

Need to connect additional piece of coax to it.

Do you basically mean you need an extension cord? 

Where is your modem now (with computer in kitchen)?  Did you intend to move the modem to the other room?
