There is a hidden secret connectivity labs option in the WiFi settings

[Haytch]

Go to settings, select WiFi, click on the 3 dots, and select intelligent wifi, scroll down to intelligent WiFi and click it several times and you will get a brand new option called connectivity labs

It gives various options like the best channel setting for your WiFi

Good call. Same for S23U

Thanks. This looks interesting.

Already have it on my S22ultra I have had it quite awhile now but I'm not sure what it actually does.

There's an option called home WiFi inspection. You basically walk around your home and it will tell you where is the best place to place your router for the best connection and also tells you where the connection is bad

Good find. Some useful info there.

What do you think the "Auto reconnect to carrier Wi-Fi" option do?

Anyone know what "DAD check" is at the bottom of the "Network diagnosis" list in the "Wi-fi and network diagnosis" section? The connectivity check and dns check work normally, but the "DAD" check just says, "Start DAD test" and then nothing else happens. There's no follow-up button to push either. What gives?

@INickedThisName: When a device is assigned an IPv6 address, it needs to confirm that no other device on the network is already using that same address. DAD (Duplicate Address Detection) is the process used to achieve this.
