Xfinity DNS and Roon


I have had problems in the past when streaming through Roon with skips and interruptions in music using Xfinity fiber optic service.  The Roon community monitor suggested that I change to a third party DNS such as Google.  My router is an Arris X5001.    I have tried to change the DNS on the router and the option is greyed out.  Trying to get a competent human to discuss my issue is impossible.

Does anyone know if it is possible to change DNS using Xfinity service?  Would a separate internet service just for HiFi be beneficial?

Thanks

Thanks.  So it doesn’t seem that it is not allowed by Xfinity them.  Just wondering if it is locked on this particular router.  It is fiber optic but I wouldn’t think that would matter.

You are using THEIR equipment, right? It is locked to them. Why I don't use their equipment. I really dislike comcast because of that.

1. DNS is not likely to be your problem but you SHOULD use OpenDNS.  Intermittent streaming is more of a network quality issue.

2. Your Roon device can have it’s DNS set locally, for instance every Mac/PC/Tablet lets you set the DNS service in the network settings, regardless of upstream components. This will override the router.

3. For security reasons I don’t use the cable provider’s router. In some cases they may give you a modem for free, and turn off the Wifi features. That’s fine. You buy your own Wifi router and wire it downstream from Xfinity or whoever, then you have 100% control AND can turn off remote access, which is a key security feature. They may break into my cable provider’s router but they won’t get any further.

I am not aware of an aftermarket router that will work with the non-standard fiber optic cable that Xfinity uses for my area.
