2024 Mac mini network issues

I purchased a 2024 Mac mini w/ M4 Pro chip and have been having network connectivity issues frequently and randomly. This is noticeable in the following two ways:

1. Zoom freezes and/or displays the message "Your internet connection is unstable"
2. When using Google Drive (drive.google.com) my browser sometimes displays the message "You are offline"

I have 1G (download) service and frequently run speed tests, which are just fine.

I have a 2023 MacBook Pro and have no network issues with it. I recently replaced all network patch cables with Cat 8. Since my laptop has no issues, I can only assume it is one of two things:

1. a hardware issue with the 2024 Mac mini
2. a software issue with Sequoia (the Mac mini is the only Mac I have that is running Sequoia (15.2 - it's up-to-date))

NOTE: I prefer to run wired-only!! The issue does not seem to occur if I run dual (wired & WiFi) or just WiFi.

Is anyone else having trouble maintaining a steady and consistent internet connection with their 2024 Mac mini?

Does anyone have any suggestions on how to further pinpoint the source of the problem and/or correct it?

I am ready to return the Mac mini and thought I would try here before doing so.

(FYI - I had the same problem with the first unit I purchased. So, I bought a replacement and I am experiencing the exact same problems.)

Thanks in advance for your help!

Warm regards,

Mike L
