Open DNS

I’m trying to set up OpenDNS on my network to closely monitor all the devices in my home, but when trying to set it up through the admin page, I’m unable to. Is there a way to do this? I can’t seem to find any articles on this anywhere

Hi @mimijae

If you are using a Comcast-supplied device, you may not be able to change the DNS settings. Smiley Sad Consider purchasing your own equipment if you need that level of access.

I purchased an arris surfboard modem. I read somewhere that I can connect both the surfboard and the Comcast Arris TG1682G, and set up the OpenDNS on the surfboard admin page and still use the xfinity admins page features. But I can’t find the forum on that again :/

You need a router, not a modem. Once you get a router, connect it to your Comcast gateway and set the gateway to Bridge Mode. Instructions here

 

Or even better, since you already bought a modem, return your Comcast gateway, buy a router, and activate the new modem and set it up with the new router. You can save yourself the monthly $11 rental fee by returning the leased gateway.

Re: Open DNS

Would I be able to set up the surfboard as the modem, the Comcast modem/router as the router and my netgear as a range expander? We have a terrible connection throughout the whole house.

No, the Comcast gateway doesn't have a WAN Ethernet port for you to connect an external modem to. You only have room for one cable company interface in the system here - either use the Surfboard modem, or the Comcast gateway, but you can't use both. Since your original purpose here was to install OpenDNS, you still need a router to get that done. I don't know what model Netgear you have, but that might work just for that purpose. 

 

As far as improving your wifi coverage, there's a great instructional here that you can refer to for ideas.

Re: Open DNS

I’m so sorry, just to clarify, so I cannot connect the surfboard to the internet cable for my modem, and connect the Ethernet from the surfboard to the Comcast Arris as the router?

AFAIK the router component / portion of the Comcast combo gateway devices can not be separated out from the modem portion and used independently.
