Thanks!
Yes, the coax line goes straight from the main splitter to the G110 router and each other line goes directly to each individual room - so just individual runs.. this setup was set before FIOS was in the house (It was comcast before then and when FIOS showed up they just reused the connectors/coaxial cables), the coax cables are used mainly for moca setup to for now (I have Tivo units only and no VZ boxes) so the internet is delivered to the Fios router via Ethernet (100/100) - I have planned to replace the G110 router at some point but I haven't come around it yet..
I also remember Comcast had a a/c powered splitter (like the one in the picture) connected to the line IN and the FIOS technician took it out, he said it was not needed anymore..
Maybe is not worth the trouble and leave it alone... thanks for your comments, I appreciate it.
