1. Interference or Hardware Conflict

Your metal desk and clamp-mounted stands could be affecting Wi-Fi signals if you’re using Wi-Fi instead of Ethernet. Metal can reflect or block wireless signals, especially if the Mac Mini is tucked behind or surrounded by it. Test: Try moving the Mac Mini out from under the desk or closer to the router to see if stability improves.

2. USB Hub Interference

Some USB 3.0 hubs or devices can interfere with Wi-Fi signals, especially in the 2.4 GHz range. Since you’re using an aftermarket USB hub, it could be causing RF interference. Test: Temporarily disconnect the USB hub and see if the issue improves. If so, you might need a shielded hub or switch to 5 GHz Wi-Fi if not already on it.

3. Wi-Fi vs. Ethernet

Are you on Wi-Fi or Ethernet? If Wi-Fi is acting up: Try switching to Ethernet temporarily to test. If you’re on Ethernet and it’s freezing, your network port or cable might be faulty. Test: Try a new Ethernet cable. Switch ports on the router. If using a USB Ethernet adapter, test without it (or with a different one).

4. Background apps or processes

Sometimes background processes (iCloud syncs, Time Machine backups, etc.) can choke your bandwidth. Test: Open Activity Monitor > Network tab to see if anything is using a lot of data.
