Android Wi-Fi Keeps Disconnecting? Real Fixes That Actually Work

Android Wi-Fi keeps disconnecting fix

Your Android connects to Wi-Fi just fine but keeps dropping the connection after a few minutes. Or it shows connected but nothing loads. Or it switches to mobile data without telling you. Here are the real reasons this happens and how to fix each one.

Disable Wi-Fi Power Saving Mode

This is the most common cause and the easiest fix. Android aggressively cuts Wi-Fi power when the screen turns off to save battery. Go to Settings > Connections > Wi-Fi > Advanced (or Wi-Fi Preferences) and find Wi-Fi Power Saving Mode or Keep Wi-Fi On During Sleep. Set it to Always. This prevents the radio from switching off whenever the screen locks.

Forget the Network and Reconnect Fresh

Corrupted network credentials cause persistent connection issues. Go to Settings > Wi-Fi, long-press your network, and tap Forget Network. Then reconnect from scratch by entering the password again. This rebuilds the connection profile and often resolves mysterious drops that appeared for no obvious reason.

Turn Off Adaptive Wi-Fi / Smart Network Switch

Samsung phones have a feature called Adaptive Wi-Fi or Smart Network Switch that automatically switches to mobile data when Wi-Fi signal quality drops below a threshold. This can feel like Wi-Fi disconnecting. Go to Settings > Connections > Wi-Fi > Advanced and disable both Adaptive Wi-Fi and Auto Connect. Now the phone stays on Wi-Fi unless you manually switch.

Check Your Router’s 2.4GHz vs 5GHz Settings

If your router broadcasts both 2.4GHz and 5GHz bands, your phone might be jumping between them and momentarily losing connection during the switch. Log into your router settings and either rename the bands differently (so you can manually connect to the stable one) or enable Band Steering if your router supports it properly.

Reset Network Settings

Go to Settings > General Management > Reset > Reset Network Settings. This clears all saved Wi-Fi passwords, Bluetooth pairings, and mobile data settings. You’ll need to reconnect to all Wi-Fi networks, but it completely refreshes the network stack and resolves configuration issues that cause persistent drops. Back up your Wi-Fi passwords first.

Check for IP Address Conflicts

If multiple devices on your network have the same IP address, connections drop. Try setting a static IP: go to Wi-Fi settings, long-press your network, tap Modify Network, switch to Advanced, change IP Settings from DHCP to Static, and set a specific IP address (like 192.168.1.150 — higher numbers are less likely to conflict with other devices).

Update Router Firmware

Outdated router firmware can cause compatibility issues with modern Android devices, especially after Android updates. Log into your router admin page and check for firmware updates. Most routers can be updated with a single click from the admin panel
