Is your Galaxy S23 Ultra having Wi-Fi issues? You're not alone.

The only issues I have with my phone and WiFi is when I am at the edge of the coverage and it's spotty, but that is expected.

Have you tried resetting your connection settings and re-connecting?

Settings: General Management > Reset > Reset WiFi and Bluetooth Settings > Reset Settings button

Warning: You will need to re-pair your BT devices and reconnect to WiFi networks.
