Getting router to work with cable box.

by bukwus / December 3, 2013 3:19 AM PST


I have a pretty standard Comcast cable box with my TV and two consoles in the living room. In the next room I have a modem and router connected to it for WiFi. I tried disconnecting the router from the modem and connecting it via Ethernet cable to the cable box, but had no luck with WiFi. My goal is to have the router in the same room as the TV and consoles.
Is there a way to connect the router to the cable box?

Many thanks,

Clarification Request
No model numbers.

And without that I can't comment if the cable box has settings to change.

HOWEVER when I install the router I power down the router, move the Ethernet cable to the WAN port of the router then power up the cable modem, wait for lights to go stable then power up the router so I can configure the router.

Your post didn't reveal much.

I've had Comcast for years

By now it's probably been more than a decade. <looking at empty wallet.> Not once have I ever connected my cable box (either DVR or plain cable tuner) to my router. It just wasn't necessary, since I had a separate cable modem. It normally is a length of RJ6 cable from the wall into the back of the cable box (now, DVR). A Cable box doesn't need wifi, but a direct wired connection to the CMT head-end over coax.

Hint: if you split the coax which is in the same room as the cable box, you could relocate your cable modem to that more convenient point near your TV/othergear. <thinking about how many times I've moved all the crap around in various homes/apartments(!)>

<FWIW, I had to re-read your post since I originally had the same thought as Bob.>

Seeing that I was unclear

Thanks for this reply. I'm seeing from both Proffit's and your replies that I'm not being clear. Sorry about that. My goal is to be able to connect my consoles (PS3 and Xbox 360) via ethernet to the router. The modem only has a coax cable-in port while the cable box has both in and out. My choices, as I understand it, are figuring a way to make the router work while connected to the cable box or run a VERY long ethernet cable from the modem in one room to the router that I'd place in the living room (where the consoles are). I'd like to avoid the long ethernet cable so that's why I'm posting on the forum to get some advice and hopefully learn something new.
If model numbers are necessary, I'll post those next.

A wireless bridge would work too

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
