Hi, I currently have Roadrunner and I have the modem running to my room. I'm having Fios installed this week, my question is, can I use the existing wiring for my Roadrunner cable for Fios? For example can I just unplug the Roadrunner modem and just plug in the new Fios modem and it works? I'm not getting any TV or phone service installed, only internet connection. I'd like to know before if the existing cable can be kept so I can make preparations when the installation guys come to make it as quick as possible.
