Hi All, I live in a two family house with one Comcast ISP connection (neighbors in basement apt, I live in upper part of the house) and the router is located in the basement. We've been having problems with connectivity and I want to add a second modem to our house so I can connect an old Linksys router I have. Is this possible? I know the least complicated (but most labor-intensive) way is to run CAT 5 wire from the first router to the second, but I don't want to have to drill holes in the floor of our rental house. Every room in the house has a coax jack and I'd like to connect one of those to a modem and router I have, so we can have a more reliable connection. Anyone have experience with this?
