iphone 13 pro can't discover 5 Ghz wifi AP
I was setup my AP with 2 frequency 2.4 Ghz and 5 Ghz, but when i'm trying to connect from my iphone 13 pro, i can't see the 5 Ghz AP, i'm only see AP with 2.4 Ghz.
And test it with any other iphone, it's same from iphone 11 to 13 pro max, but it's work in iphone 6. Iphone 6 user able to discover the 5 Ghz AP and connect to it.
Is there any one have a solutions on this ? upgrade to IOS 16 not solving my problem.
Thanks
iPhone 13 Pro, iOS 16
