Macbook Pro (M2 Pro, 2023) doesn't connect to 5GHz Wi-Fi network at all

Well at least they tried! The Apple Tech's at Smithhaven Mall Apple store wouldnt touch it saaid they cannot test network connectivity because their store network is a secure Apple network. My answer was,"don't you have a small local network setup available to test these type problems out? They said no so I took it back to where I purchased it (M2 Max 32GB 1TB) 16" but if I cant connect to computers on my home network then why bother with an expensive doorstop. At the place I bought it was even worse the tech along with their Apple tech just said well take it back as a return! Strange as it is and from the questions and comments on this forum and others I was able to connect to the router, and the internet but the two Macs on my local network were visible in Network but would not make a connection. You know something isnt right when a retailer wont fight to keep a sale, he knows there is an elephant in the room,Apple say what ?

My question here is, What is Apple doing to find a fix or a workaround? All I see are disgruntled customers and I am currently one although the first unit I had purchased and since returned was able to reach the internet but I swore I was able to access my local home network then I did a security upgrade and since then it didnt work so I first went to Apple's genius bar wheree they wouldnt work on a network problem and so I took it back to place I bought it,like I said it worked fine with wifi but the other problem was a deal killer and they took it back as a return and so for a day I had no new macbook pro ( my older 2016 has a bad screen but works with a monitor) and I bought a M3 pro today and maybe tomorrow I will open the box or return it unopened.

I cannot remember how i fixed it now but I tried a few things that seems have fixed the issue.

1. Change the HDMI cable - I think to have a good one makes a difference
2. Add HDMI to USB-C Adapater (I use one because it works well with monitor configurations)
3. Restart your router (mine cannot even seperate channels so unable to pick 5GHz)

Haven't had any issues since

Same here, I had the same issue and believed it was just the wifi problem, but hey, all my devices connect no problem, including my PCs Android and so forth.

Funny how Apple keep surprising me all the times, overpriced/luxury product that doesn't work accordingly to their pricetag.

Same issue, contacted the Apple online service, provided me with tons of useless solutions such as, what is the model of your router, did your router is updated?

I litterally got the same problem cross over any routers with 5G in so many different places and countries.

This mac M2 since I bought it from the store never connected to any 5g networks while all my other devices, Ipad pro, PC, any other devices; including a cheap Android phone, can.

It's really a disgrace to buy such expensive piece of equipment, with sealed hardware inside to be sure no one can fix it, and yet this garbage doesn't work.

Even Apple can't give a solution to that problem, now they advised me to re install the OS, LOL, I do try this solution and will patiently wait for 3 hours but I am already pretty much sure it's not gonna work out.

Anyway...

I am so done with Apple seriously.

The problem with buying a new router for your laptop, is that the point of having a laptop is to be connected anywhere and be mobile.

I don't see myself buying a router to every single place I go.

This solution is ridiculous, glad it works for you, now you can use your laptop in your home on a 5g network.

That gave me about 5 or 6 more minutes connection time over the 1 to 2 minutes before, on my Intel Mac. All other Apple devices work flawlessly, been on the phone with at&t for 3 days with mainly getting there must be something wrong with my Mac, not the case it connects and run flawlessly on other networks. Are at&t and Apple butting heads?

I believe thats what my settings were originally but I read somewhere that Mac's prefer WPA2 so thats where I am now. I'am with you on not finding fixes and workable solutions and still believe this is a ISP problem. I've spent the last 3 days with AT&T support with zero being accomplished. The 5 ghz is completely worthless and the 2.4 band still drops occasionally needing to reboot. If I find a workable solution, I will post it here, shame so many people think they have the answer and don't!

Just for the sake a clarity, of course they have trouble testing and troubleshooting network connectivity issues.

if it works on their network in store, then they have no way to go further. Not saying the machine doesn’t have issues, just saying troubleshooting is just a standard process, and network testing can only happen onsite.

I have a similar problem with my 2 MacBook Pro's ( 1 intel and one M3) and my granddaughter's 2 MacBook Air's on at&t's internet air service. All the devices connect to both the 2.4 and 5 g radios and the MacBook on ethernet cable but the data transfer (bandwidth) on all bands is very slow to non existent, 5 g being the worse, speeds exceed advertised rates. All the devices work perfectly on other networks, now we are having issues on the other Apple devices ( iphone, ipad, and iwatch) not to the same extent but still at times slow to no data transfer even though they say they are still connected to the network. I have contacted at&t and Apple multiple times, at&t says it must be the devices, Apple diagnosis can find no errors. It looks like the internet air is prioritizing the bandwidth, with the MacBooks on the bottom, which makes no since. At&t changed some router settings witch helped minimally but now if the device is idle for a period of time I have to reboot the devices and the router to re-establish connection. I have owned a MacBook for nearly 8 years and never found a better support group anywhere (at&t should take note!) so I don't believe this is an Apple problem with the evidence at hand. I equate speed and bandwidth, comparing a gnat flying at 600 mph, great and wonderful but no payload but a C5M flys less than a 100 mph difference but has a payload of over 180,000 lbs.!

I wish it was that simple for me :/ I don't have anything connected.

Same Issue 2023 M2 Pro 14"

did you ever find a solution to this?

To suffer. I am also having the same issue.

This seems to have solved my problem with the M3 Pro
