"Tuning" a cable jack to the outside?

Hi all, the other month I moved into my new house for school and had Comcast come out and install the cable and internet. I had him set the modem up in a room downstairs but now I want to move it upstairs due to one of my roommates needing to connect through a cable. I remember him telling me that he "tuned" that particular cable jack to the outside box or something of that nature. What exactly does this mean and can I move the modem/router upstairs without significantly decreasing speed? (I have FIOS at home so this is my first experience with a cable modem)
 
Is there a good way to measure the change? I was going to use game ping as an indicator but that fluctuates too much.
 
It is probably irrelevant.. if it works and passes 48 hours of continuous service with no loss of connectivity and delivering consistently good transfer rates it is fine. Use a ping test, speedguide / some other speed test site... dslreports, whatever....

Basically you just want the shortest possible cable that ideally doesn't have many/any other cables directly split off of it or so on... ideally a cable that isn't old / crusty / cracked / painted et. al.
But if it works it is probably as good as it is going to get; even reinstalling the run with new cable probably isn't going to make it better. If it totally stopped working well in the rain or something then maybe the cable could be leaky or whatever but really that isn't likely.
 
What he most likely tuned is the signal strength to the modem by adding attenuators back at the stalk.

Unless he tuned you to the bottom of the envelope, you should be able to add a little cabling without worry. If you plan to go wild with splitters & such, then you may need them to come out and tweak the system again.
 
Well I was actually planning on moving the router to my room upstairs. Each room in our home has a jack in it. I was going to connect the modem to my jack on the second floor. Sorry for not being more specific.
