New Mac Mini M2 has constant issues with wifi. Its unusable. Ethernet works perfectly, but when using wifi the connection will consistently drop packets. Wifi works perfectly with older Mac mini M1, MacBook Pro, Intel Mac in the same small office. I have turned off all other devices and still have same issue. Did a factory reset and same issues.
Mac mini (2023 with M2)
**Solution discovered** (but Mac MUST release a fix for this soon. Very unhappy with my new Mac Mini M2 Pro.)
it is a problem with Wi-Fi 6 routers that combine all the bands under one SSID (Wi-Fi name).
If you have Spectrum, their “smart” router doesn’t have the function to separate the bands and therefore will NOT work. You need to get another router and the bands have to be named separately as others have said in the posts.
this is an issue that shouldn’t be an issue, and I’m surprised no fix has come for this yet so regular people don’t have to become network professionals to get their internet to work!
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?
I'm curious about what further testing of Cable-2 and Cable-3 using Method B will show. It'd be nice to be able to use the Mac mini's HDMI port for a display so the Thunderbolt/USB-C ports could be used for other purposes other than a display. I wonder why using an HDMI to DVI cable is so bad even while grounding the HDMI plug to the Mac mini. What are results of grounding HDMI to DVI using your hand, same as paperclip grounding?
I wonder if there is any way to alert Apple hardware technicians of this forum thread.

They are already aware. A few of us have had phone calls from Apple Support engineers from Austin, Texas, who have remote connected to our Macs, had issues demonstrated to them, and they've collected megabytes of diagnostic files.
AbuYang,
I find it strange that your grounding tests of your HDMI cable's connector showed that grounding the connector improved packet loss. If your Mac mini is connected to the 5GHz channel and your port and/or HDMI cable is emitting 2.4Ghz interference could there be some kind of effect on 5GHz Wi-Fi? More research is needed.
For those with M2 Pro Mac mini Wi-Fi issues, please report what channel (1-14, 32-177, 1-233) and frequency (2.4GHz, 5GHz, 6GHz) your Mac mini is connected to and if you're currently experiencing problems. Thanks!
I've not been able to find any information on the Ugreen HDMI cable with model number 20276. At any time did you read anywhere that it was shielded? And it would be giving off 2.4GHz EMI not 5GHz, so I wonder why grounding your HDMI plug made such a difference. Unless 2.4GHz electromagnetic interference is affecting something else that is then affecting Wi-Fi. You might want to try an HDMI cable that is listed as being shielded to see if it would work without your having to ground the plug to the top case of your Mac mini.
No, never tried. I use my machine for work, so do not want to mess with it.
Once I realised that replacing my previous set-up of one HDMI cable to one screen and a second Thunderbolt to HDMI to the second screen with a pair of matched USB-C to HDMI cables (Silkland USB-C to HDMI Cable 4K from Amazon) resolved all my problems, I left it alone.
So I have a Mac Mini 2 Pro that now works perfectly but with a redundant HDMI port (and loss of one Thunderbolt port because of that) but it works great and I will leave it like that.
I cannot see Apple taking all those machine back and reworking the HDMI port, but I assume they have changed the manufacturing of new ones to avoid the problem? If so, try taking yours back for exchange.

Could the HDMI cable be emitting 2.4GHz Wi-Fi signal perpendicular to the cable? I wonder. I see in AbuYang's video that his HDMI cable is coming straight out from his Mac mini, but can't tell if its looped back around towards the Mac mini. AbuYang, where is your HDMI cable routed?
I meant to write "...Mac mini then plugging the other end into your display without making the cable PARALLEL to the back of your Mac mini close to your Mac mini?, not PERPENDICULAR close to your Mac mini, sorry.
Hi there,
I will have a technical call with Apple today. The result should be in replacing the logic board an/or the WiFi antennas. I think this will solve the issue. Keep you updated.
PS: How do I mark someone in the forum, so that his/her name is blue highlighted?
Hi tonglokman
I already have been to the Apple Store last Saturday. They told me that an online replacement would be faster, because the stores don't have the needed parts available. It could take up to two weeks.
PS: Did it work? ;-)
Just went to the Apple Store, again.
The technician executed some diagnostics without any negativ result. Was it the same for you? tonglokman
I escalated it and will have a support call tomorrow with the next level technical support.
Not yet, because I never had in mind that the issue could also be the USB-C to DP cables.
I will check this tomorrow morning and report the results.
But nether less the issue should be a bad design by Apple, in my opinion.
