First, you need to reboot your modem. Once it's unplugged from the wall for 60 seconds, plug it in and let it fully boot back up. Now, unplug your router for 60 seconds, plug it back in, and let it fully boot up. Now, go into your S24 Ultra's Wi-Fi settings menu. Make sure that Connectivity Labs is not activated; turn off the "turn Wi-Fi on/off automatically" feature. Now, go back to Advanced Wi-Fi settings, click on the Manage Network section, and delete all saved networks. Once that's completed, reconnect your phone to your home Wi-Fi, leaving the auto-connect switch on. This should solve your problem. It happens because Wi-Fi routers, so-called "Smart Connect" routers, send out up to three different signals (2.4 and 5 GHz, respectively). Sometimes, it will connect to one that doesn't have enough throughput to give you data, so your phone is sort of guessing what to do, and your router doesn't help the situation. Just make sure to clear out your save Networks and reconnect as new if it doesn't prompt you to put in a password go back in make sure it's deleted and try again. hope this helps
