Fix #1: Restart the Galaxy S26 and the router

This clears the most common post-update network handshake issues on both the phone and the access point.

1. Restart the Galaxy S26.
2. Unplug the router for 30 seconds.
3. Reconnect and test WiFi again.

Fix #2: Forget the WiFi network and reconnect

Old credentials or damaged network profiles often survive updates and cause internet access failures.

1. Open Settings > Connections > Wi-Fi.
2. Tap your network, choose Forget, then reconnect.
3. Test whether websites and apps load normally.

Fix #3: Turn off VPN, Private DNS, and ad-blocking apps temporarily

If DNS requests fail after the update, the phone can look connected while all traffic stalls.

1. Disconnect any VPN app.
2. Open Settings > Connections > More connection settings > Private DNS.
3. Set it to Automatic or Off and test again.

Fix #4: Toggle airplane mode and WiFi scanning features

Refreshing the radios can restore internet access without a deeper reset.

1. Turn Airplane mode on for 15 seconds, then off.
2. Reconnect to WiFi.
3. If needed, disable nearby scanning features briefly and test again.

Fix #5: Reset network settings

This removes damaged network data left behind by the update and rebuilds WiFi, Bluetooth, and mobile connections from scratch.

1. Go to Settings > General management > Reset.
2. Tap Reset network settings.
3. Reconnect to WiFi and check whether internet access returns.

Fix #6: Check for a router firmware issue or ISP outage

If other devices are also unstable, the problem may be with the network rather than the phone.

1. Test another WiFi network if possible.
2. Update the router firmware.
3. Confirm there is no ISP outage or captive portal problem.

Fix #7: Install the next Samsung update

Samsung sometimes patches WiFi regressions in a quick follow-up build.

1. Open Settings > Software update.
2. Install any available update.
3. Restart and test the connection again.

If the Galaxy S26 has no internet on every WiFi network even after a network reset, back up your data and consider a factory reset or Samsung service support.
