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

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.!

Hi,

in the end I found out my usb dock was causing the issue, also on my older macbook I found out later.

good luck, I hope it may help you.

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.

Hi, the solution is really easy. Check your Wi-Fi adapter channels that could be used for 5g. And change it in router settings.

As a retired Network Administrator IMHO you should use a different name for higher wi-fi bands! This will separate the two/three wireless transmission from a router!

Same here. I replaced the USB dock for one compatible with Mac M2. This solved my problem. Now the Mac Air is using the 5 Ghz band

same here, the problem was with the HDMI cable, changed it and everything works just fine, Thanks a lot 💐

This seems to have solved my problem with the M3 Pro

thank you omri4747

never in a million years would i guess the hdmi cable was pulling my wifi into 2.4ghz !!!
