How to Fix Galaxy S26 WiFi Keeps Disconnecting After Update

If your Galaxy S26 keeps disconnecting from WiFi after an update, the issue is often tied to saved network data, router compatibility, smart switching features, or temporary firmware bugs introduced after the latest patch. The phone may reconnect on its own, but repeated drops can break calls, app downloads, streaming, and messaging.

Try the fixes below in order for the best results.

Fix #1: Restart both the phone and router

Restart the Galaxy S26 first, then unplug your router and modem for about 30 seconds before powering them back on. This clears temporary connection glitches on both sides.

Fix #2: Forget the WiFi network and reconnect

Go to Settings > Connections > WiFi, tap the affected network, choose Forget, then reconnect by entering the password again. This removes corrupted or outdated saved connection details.

Fix #3: Turn off WiFi Intelligent features temporarily

Open Settings > Connections > WiFi > Intelligent WiFi and temporarily disable features such as switching to mobile data, WiFi power saving, or automatic hotspot switching if they are enabled. These features can sometimes trigger unwanted disconnects after a software update.

Fix #4: Reset network settings

Go to Settings > General management > Reset > Reset network settings. This clears saved WiFi, Bluetooth, and mobile network settings and often fixes disconnecting issues after firmware changes.

Fix #5: Check if the issue happens on one WiFi network only

Test another network if possible. If the Galaxy S26 disconnects only on one router, the problem may be tied to the router band, channel width, WPA settings, mesh handoff, or firmware rather than the phone itself.

Fix #6: Separate 2.4GHz and 5GHz bands if your router allows it

Some phones struggle when a router aggressively moves them between bands under one SSID. If your router has combined bands, create separate names temporarily and test each one.

Fix #7: Wipe the cache partition

Boot into Recovery Mode, choose Wipe cache partition, then reboot. This clears temporary system files that may have become unstable after the update.

Fix #8: Install the latest software patch

Go to Settings > Software update and install anything available. WiFi bugs introduced in one build are often fixed quietly in the next maintenance release.

Fix #9: Try Safe Mode

If disconnects started after installing a VPN, firewall, ad blocker, or connectivity manager, boot into Safe Mode and test WiFi there. If the issue disappears, uninstall the app causing the conflict.

Fix #10: Factory reset as a last resort

If the Galaxy S26 still drops WiFi on every network after all previous steps, back up your files and do a factory reset. That is the most reliable way to remove persistent update-related corruption.
