Step by step

1. Restart the router

   Unplug its power cable, wait a moment and plug it back in. Wait until its lights settle before testing again.

   Done

2. 

   Forget the network and join again

   Settings, Connections, Wi-Fi: touch and hold the network, tap Forget network, then tap it and enter the password again. Saved networks are also listed under three dots, Advanced settings, Manage networks.

   Done

3. 

   Open Private DNS

   Settings, Connections, More connection settings, Private DNS. Ours was set to Automatic.

   Done

4. 

   Choose Automatic, not a custom provider

   The phone itself warns that with a provider hostname set, it cannot connect to the internet at all when that provider is unavailable. Automatic falls back to your network's own DNS servers.

   Done

5. 

   Check Switch to mobile data

   Wi-Fi, three dots, Intelligent Wi-Fi. With this on, the phone may quietly use mobile data on a weak Wi-Fi, which can hide the real problem while you test.

   Done

6. 

   Reset Wi-Fi and Bluetooth settings

   Settings, General management, Reset, Reset Wi-Fi and Bluetooth settings. Saved networks and paired devices are removed, nothing else. Steps: how to reset network settings on a Samsung Galaxy phone.

   Done

About this guide

The Wi-Fi symbol is there, but nothing loads. Either the router has lost its own connection, or the phone cannot use it. Check the router first: if other devices are offline too, the phone is not the problem.

The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ. We only looked at these screens on our phone and changed nothing.

Good to know

Public Wi-Fi in hotels and trains often needs a sign-in page first. Open a browser and visit any website to make it appear.

Samsung Members has a Wi-Fi test under Support, Phone diagnostics.

If the Wi-Fi keeps dropping rather than having no internet: Samsung Galaxy Wi-Fi keeps disconnecting? 6 things to check.
