Xfinity DNS and Roon

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.  
 

That is the issue with fiber - it is specific to the company.
