Greetings,
Background: I don't understand the difference between modems and DECAs.
Having cut the cable, the only service I now have is internet service coming in through a coax cable.
Current Setup (cheap & working perfectly):
I have two DECAs (DIRECTV Broadband DECA Ethernet to Coax Adapter (DCA2SR0 ) Generation II) set up as follows:
From outside coming in coax (in office upstairs) -->modem -->ethernet cable -->router (for wifi)-->ethernet cable -->powered DECA#1 -->coax cable (in wall to downstairs TV room) -->powered DECA#2 -->ethernet cable -->Roku-->HDMI -->TV
Question: Why doesn't the following setup work for me to have internet through coax cable only --no wifi?
From outside coming in coax (in office upstairs) -->connected by a barrel connector to a coax cable (in wall to downstairs TV room) -->DECA#2 (downstairs) -->ethernet cable -->Roku-->HDMI -->TV
It seems to me that since the DECA#2 (downstairs) is converting the ISP coax signal to an ethernet signal, that the modem, router (no wifi), and powered DECA(upstairs) adapter could be eliminated, and still receive a wifi signal.
Is there something that the modem does that the DECA does not? From what I have read, both the modems and the DECAs convert the coax signal to ethernet signal. Does the modem have to do somekind of handshake or something else in order to receive a usable ISP signal via the coax cable?
Thanks!
