Iphone 14 Pro Max 5ghz wifi problem

Hi I dont know if im the only one experiencing this but ever since the last IOS update, my connection with my 5ghz WIFI has been a hit or miss.

I have no problem connecting to my 2.4ghz WIFI but when I try to connect to my 5ghz WIFI there’s 4 scenarios that happens.

First: Its connected but no internet (Even though the WIFI have internet)

Second: The 5ghz WIFI is not even going to show in the list of network to join.

Third: It will just say “Unable to connect to the wifi network”

Fourth: It will connect to the wifi and will have an internet but it won’t last for long till the wifi signal vanishes and you won’t even see it on the list of available networks.

I have tried doing it in my ipad air 5 and have no issue connecting to my 5ghz WIFI.

It’s really just my Iphone 14 Pro Max with Ios 16.5

Also yes I am close to my wifi network it’s literally in the same room as me.

This has never been an issue before.

And yes im talking about the wifi frequency.
