I'm trying to get hardwire connected speed for downloads for my Xbox and laptop, however my modem is all the way upstairs and too far away to run an Ethernet cable. I also have a second modem not doing anything from my previous apartment. I was wondering if there was anyway I could hook up the free modem down here in the basement and use the internet I'm already paying for, if I can, what the procedure and consciences would be? And if not, what other alternatives there would be?

Obviously I'm not super well versed so please be gentle...
