Fix #1: Forget and reconnect to the Wi-Fi network

A clean reconnection can fix a damaged saved profile.

1. Go to Settings > Wi-Fi.
2. Tap the affected network and choose Forget.
3. Reconnect using the password and test stability.

Fix #2: Restart both the phone and router

Short-term routing or DHCP issues often appear after device updates.

1. Restart the Galaxy S26.
2. Unplug the router for 30 seconds and power it back on.
3. Reconnect once the network is fully back up.

Fix #3: Disable Intelligent Wi-Fi switching features temporarily

Auto switching and network scoring can cause repeated disconnects on some builds.

1. Open Wi-Fi settings and look for intelligent switching or adaptive connectivity options.
2. Turn them off temporarily.
3. Monitor whether the connection stays stable.

Fix #4: Reset network settings

This clears broken wireless profiles and connection rules left behind after the update.

1. Go to Settings > General management > Reset.
2. Choose the network reset option.
3. Reconnect to Wi-Fi and test again.

Fix #5: Try 2.4GHz or 5GHz separately

One band may be less stable than the other after a router or firmware change.

1. If your router broadcasts separate SSIDs, test each one.
2. Stay on the more stable band.
3. Also disable WPA3 temporarily if older smart-home gear is involved.

Fix #6: Install a follow-up update

Samsung often fixes wireless bugs quickly once enough devices report them.

1. Go to Settings > Software update.
2. Install any pending patch.
3. Update the router firmware too if available.

When to escalate the problem

If the issue started right after an update and none of the software fixes help, back up the device and contact the manufacturer or carrier. Persistent hardware-like symptoms can still be software-triggered, but they need deeper diagnostics when the common fixes fail.
