Well, a good place would be to read the Roon’s Best Networking Practices FAQ. If you do, under the router sections, it suggests not using Apple networking gear as it has issues.
Finally, we strongly recommend against using Apple network devices such as the Apple Airport Extreme and Airport Express (note: it’s fine to use the Airport Express as an Airplay device). To ensure the best performance, we recommend against using these devices.
I am not official Roon support just a friendly fellow user and hopefully helpful volunteer moderator. You asked about networking and mentioned apple in your equipment above. I was just pointing out that since you seem to be having a recurring network issue, that Apple products have been known to be a potential source for that issue.
Before just going out and purchasing something, I would suggest you hang tight until support can discuss the issue with you in detail.
I am very sorry it’s been this long until we got a chance to reach back out, especially for an issue as important as discovering your Core, the brains of the entire system. I can see how anyone could get frustrated in such a situation. Please, accept my apology
@Rugby, we couldn’t be more grateful for your immediate help
I was wondering if this issue is ongoing, or if there’s anything else we can help with?
