I still think you should try my recommendations.  Try the DNS route first, then try if possible to reduce MTU to 1300.

@erik_squires  I will try setting up new router and move the entire routing over first.  I also chat with AI 'who' indicates the followings.  If the issue persists, I will try changing DNS / MTU route.  All right?

Will It Fix Qobuz Dropouts?

For Qobuz streaming:

Almost certainly no if the issue is mid-track dropouts.

Why?

DNS is only used:

• When resolving the stream server

• At the beginning of playback

• Occasionally during session refresh

Once music is playing, DNS is no longer involved.

If you are hearing:

• Dropouts during a song

• Buffering pauses

• Skipping at high-res

That is:

Packet loss, buffer underrun, routing instability, or Wi-Fi issue — not DNS.

Sigh...... sigh.... 

Your chatgpt is only partially right.  DNS does not affect the quality of a stream, but it may affect which network end point a Qobuz stream is served from.  Every DNS server does not always resolve the right end point for every service.  For instance, if you are in Texas and the DNS server resolves to a Qobuz service in Ireland then you are more likely to have network issues.  

For residential Internet customers, by default your router will use the Internet provider’s DNS servers/services, so besides the backbone and on/off ramp locations the other variable between say AT&T and Comcast is the DNS servers themselves. 

I worked in ad tech, and helped monitor global network operations, not my core job. While this type of misconfiguration was rare they do happen. 

In any event, you should use OpenDNS or Quad9 just as a matter of privacy. :) 

More likely this is an MTU issue or a route issue. If you can find the exact IP address used for streaming (not necessarily the web page) you could run traceroute and ping and gain more specific information about the pathway between you and Qobuz.  

@shooter41  I've had AT&T fiber for 4 plus years - zero issues

@facten I have people in my own neighborhood that claim they never have issues with them. Doesn't mean that they don't still have some widespread problems. Again, their own tech told me as much...

Question with respect to the Ops issue for you more technically inclined folks who've responded -  since supposedly streaming movies and tv programs requires more bandwidth than music why wouldn't the OPs issue also occur with those if it were modem equipment or setting issues? Txs
