Chiming in to say I'm still having the same issues. Thankfully I have access to ethernet in my spot in my home office, which is the ultimate band-aid fix. If I didn't, my computer would be unusable. Sadly, I've found it more convenient to just plug it in and let it ride with poor wifi but a strong hardwire connection.
Some other bandaid fixes that have worked for me:
- Turning the Mac Mini on its left side (with the front facing power light toward the top increases the signal strength. The wifi antennas must be on the right side of the device. I also bought a plastic Mac Mini stand to keep it propped up well.
- Minimizing the use of the thunderbolt ports in the Mac Mini. When I'm using 2 or fewer of the 4 thunderbolt ports in the back of the computer, my Signal to Noise ratio (SNR) is in the high 30s, with about 30% signal noise. As soon as I plug in a 3rd (and 4th) device to those thunderbolt ports, the noise goes up into the mid 50s and the SNR drops to the low 20s. So if you're able to, try not plugging too many things in to the back of the computer. (Hilariously depressing that a solution to this problem is to not utilize your $2500 computer to its full potential.)
- Again, this computer would be UNUSABLE if I did not have access to ethernet. The Wifi is awful, while every other device on my gigabit network thrives wirelessly.
I've also had some issues with my OWC Thunderbolt 4 Dock with transferring data from one drive to another (both being plugged into the dock). Not sure if this is an issue with the Power Delivery of the dock or its relationship to the computer, or something with Ventura or Silicon. All of these things feel like a symptom of the same issue, but I can't be sure.
Truly depressing that Apple has put out a product that is borderline unusable unless the consumer uses a specific setup. I can't believe this thread with almost 300 replies and tens of thousands of views has still been ignored by Apple. A huge betrayal of the company's power users. Shame on them.
