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

MacBook Pro 16″

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.
