FIX 5: Switch to Private DNS
Some users were able to rectify this issue after switching over to a private Domain Name Server instead of the one provided by their ISP. So you could opt for Google, Cloudflare, or AdGuard’s DNS using the instructions given below and then check if your Galaxy S23 Ultra is able to connect to WiFi 6 5GHz.
- Head over to Settings > Connections > More Connection Settings.
- Then go to Private DNS and select Private DNS provider hostname.

FIX 6: Switch from DHCP to STATIC on Galaxy S23 Ultra
As is evident from their names, the static IP address is the one that is permanently assigned to your device and it remains the same even after you reboot your device.

This is because some of the users were able to resolve the WiFi issues after disabling the Fast Transition and opting for the traditional and legacy WiFi standard. So let’s execute this fix and test out the results in our case as well:

- Select Disable next to Fast Transition and then save the changes.
- Check if it fixes the WiFi not working issue on Galaxy s23 Ultra.

Doing so will revert all the network settings to their default state. Moreover, it will also remove all the paired Bluetooth devices and the saved WiFi passwords. so make sure to sync those passwords with your account before proceeding with the below steps.
