XB8 DNS

Can you change DNS settings on the XB8? Or are we still being held captive with Comcast DNS servers like on the XB7 - which is really ridiculous……. !!!

thanks.

I believe all Comcast gateways do not allow you to alter DNS settings. I think they also hijack the DNS port so setting DNS on a device is also ignored and forwarded to Comcast servers.

You cannot change DNS with comcast equipment. It is only one of many severe limitations that xfinity places on your network if you use their hardware.  You could do like so many others have done and are doing and buy your own hardware.  That way, you will have far more control over your network, and the hardware will be far superior to anything that comcast provides.

Hello @grelf, at this time this feature is not supported on our rental equipment. Alternatively, setting the xFi gateway to bridge mode and using a personal router should let you configure the personal router's DNS settings. This should be possible by purchasing your own modem and router too.
