Mac Mini M2 wifi issues

Hi Ken. I touched the connector's metal with a (unprotected) paper clip and the transfer speed got bigger immediately. It remebered me of the old TV sets with a room antenna :).

Nevertheless, the speed was not at it's maximum and therefore I swiched my screen to USB-C cable instead of HDMI and problem solved (i unplugged the hdmi from the computer) - Now it works perfectly at max speed. I will keep you posted if the wifi problem comes back with USB C also.

Just to be clear, I would like to say that I had a Mac mini M1 two weeks ago on the same desk, with the same connectors that worked well. I have also changed the WIFI settings (separate 5G and 2,5G networks) to try to solve this issue but it didn't help.

Hi, I just unboxed my Mac Mini M2 Pro and got the same issue. After spending 2-3 hours with Apple customer support, I was recommended to contact with my internet provider which is Bell. They update the modem firmware and the problem just solved in 5 minutes. I hope this solutions work for some of you.

I had the same suggestion as they couldn't get it to work in the Apple store. They ended up reinstalling OS, instead of replacing the logic board. I ended up using a new Cat 6 ethernet cable (wasn't game to use wifi again) direct to modem and haven't had a problem since, goes like a bullet. Not sure replacing the logic board will solve the issue unless the 6E chipset has changed. Hope it solves your problem, otherwise it might be a return for refund or using an ethernet cable if you can.

Did you see this fixed with an OS update? I'm on Ventura 13.4, and I'm having the same issue. So tired of my Mac mini M2 dropping constantly. While all other devices are on the network just fine. And I do have the TP Link Deco Wifi 6E mesh routers.

That's interesting. Most people have had HDMI port interference affecting their Wi-Fi issues. Just out of curiosity, could you perform an experiment? Could you ground the HDMI port of your Mac mini to see if that improves Wi-Fi signal strength? Some other people remarked that their Wi-Fi got better when grounding the HDMI port/cable. Maybe also ground the Thunderbolt port/cable and see if that changes anything?

There is no need to touch the metal part of the HDMI connector.

Just touch the plastic part of the connector, and the response time will become normal.

Once you stop touching it, the response time becomes slow and unstable.

This is a method I have tested, but I cannot provide a detailed explanation in the form of a video.

Perhaps others can provide more detailed testing and explanatory videos. If this issue has been encountered by many people, what can be done to get Apple's attention?

Here is the download link for the video I shared.

Yes, AbuYang, touching the plastic sheath of the HDMI connector is enough to eliminate most Wi-Fi interference. I was just wondering if interference would further decrease if the metal portion of the connector was grounded. Your video and other accounts of grounding the HDMI port suggests the HDMI port is emitting EMF interference and grounding the HDMI port eliminates a lot of the Electro Magnetic Field interference.

I just called ISP and they updated it remotely and I got connection for an hour then the problem occurred again. Yesterday, I got a call from Apple senior advisor and we did something and he reported all of them to the engineering team. Now, I am waiting an email from him.

Thank you, Ken Shimabukuro, for your information.

I really hope that Apple will take this issue seriously. If the HDMI connector may generate electromagnetic interference, the chances of resolving this problem through a software update are very slim.

For now, my temporary solution is using Type-C to HDMI.

If touching the Thunderbolt 3 adapter also decreases ping time then it's not just the HDMI port that's causing Wi-Fi interference. Out of curiosity what do you have plugged into your Thunderbolt 3 adapter, TracyWI?

Nothing. Just the adapter, and the adapter does have an external SSD in it. But there was absolutely nothing plugged into the adapter externally. I had it there mainly for the external SSD, and "just in case" I wanted to connect something else.

Ken Shimabukuro, Thank you for providing the information. I've reviewed the relevant content, but it's not my area of expertise, so I couldn't understand it, haha.

Perhaps the only way forward is to hope that Apple takes this situation seriously and provides assistance in finding a solution.

Your link came through in the notification for those that are following the post. I was able to go to it, so I see the teardown. I don't know what to do with that though. I'm not going to open this thing up. But yes, I wish apple would address the situation.

I do notice Mac Studio and Mac mini users both complaining of Wi-Fi issues. I wonder if putting the Wi-Fi antenna under the computers is affecting the Wi-Fi signal in a negative way.

Those with speed and/or connectivity issues, how far away are your Wi-Fi routers?

And if shelling the plugs with EMI shielding tape would also be necessary...

I notice when AbuYang touches the HDMI cable connector he's also touching the Mac mini's case. Maybe taping the plug to the Mac mini's case with EMI grounding tape would help?
