Connecting USB streamer server to I2s RJ45 input of DAC?

Another option that will solve your problem is to try switching from your current router extender setup to a 3 unit WiFi 6 mesh unit from Amazon.  That way you will have 30 days to see if it resolves your issues.  You just need to make sure that you're not putting the mesh units or your current extender behind other electrical equipment. as that will result in intermittent interference.

Thanks. Got the cable ordered

That is something I have been considering especially considering the extenders inabilities. Though I have a top tier router. Its at the end of my house which is 66 ft long. I've s been concerned with its location ever since I started streaming with Roku, even though it does well. I would suspect that I would not need the hard wire from the router but from the access point nearby. Is that correct?

Correct you would hard wire to one of the Mesh units.
