I want to use x20 system in my 2 sty, 4000 s.f. apartment that has concrete walls and floors. I have fiber broadband with identity of modem unknown. It appears I can plug a unit into the ethernet port on the modem, and go from there. Some sources indicate I need to go into the modem/router and turn off my current wifi, while others say I can turn off the modem, and use the same name for my connection. I'm not sure I have the password for the modem, but I am sure I don't have the Spanish to debug it.
I do have an antenna on my desk, from the modem, and I think it has a coax connection to the modem. (I'm not in Bogota at this time). Question is, do I need to get into the modem/router?
