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

Since week I've got my new MacBook Pro, it's the only device that doesn't connect to my 5GHz Wi-Fi network at all. Solutions all over the web didn't help at all (resetting Wi-Fi, reboot router, update firmware on router, update to latest macOS, restart macOS, disabling Airdrop/Bluetooth/Wi-Fi, disabling Wi-Fi module, changing settings on router like changing channel and it's width), even in Safe Boot it doesn't connect to the network and always asks for password. MacBook works only on 2.4GHz network. I'm sure it's a software issue, because Apple Diagnostics Tool says hardware works correctly and even Raspberry Pi connects to 5GHz, but not the MacBook. For what I've paid 5K bucks, Tim Cook?


My router is TP-Link Archer AX55 (V1)

OS Version: 13.2 (22D49)


Please help me anyone if you have any other idea than listed above that may help

Thanks

Having the same issue over here with a M2Pro 16.


I separated my two networks 2.4 and 5G, disabled IPV6, tried changing DNS, changed the router channel, and I even upgraded to Mac OS Sonoma... and now it is worse. Before it was saying "No internet connection" as if it was not able to acquire an iP address. Now it cannot even connect to the 5G.


I went to an apple store and the genius was not able to identify what was happening claiming that the network in the apple store was 5g and it was connecting fine.


Really frustrating

I finally found a solution to my M2 Macbook not connecting to my 5g network (with no problem connecting to my 2.4g network). The problem is something with my router NOT the computer. My internet is provided through my apartment building and I am only able to use the provider they contract (CenturyLink). All my other devices (including an imac, an M1, ipad, and iphones) have no problem connecting to our 5g network. However, when I would connect my M2, it would stay connected for about 5 minutes and then get kicked off. I went to a local coffee shop I could verify uses internet provider and has 5g and was able to stay online there with no issues. So, I knew it was an internet issue not a computer issue. I recently purchased a second router (Linksys Hydra Pro 6 Mesh WiFi 6 Router - WiFi Extender Replacement - MR5500-AMZ - Mesh WiFi Router for Wireless Internet ) and pluggged it into my current router (because I can't get rid of that due to my living situation) and now my M2 Macbook is able to connect to 5g no problem!!!! This took about 3 weeks of trouble shooting to get to the source and figure out how to address the issue but now the problem is solved.

Hi everyone,

It happened to me as well but I solved it.

Apparently in my case, the problem was a bad hdmi cable.

I was checking the wifi using speedtest. When I disconnected all of the cables connected to the computer and turned off bluetooth, the internet worked just fine.

After that I started a debug session to find the culprit, which was the hdmi cable. After replacing the hdmi cable to a different one it works well.
