Does your Android phone keep disconnecting from Wi-Fi and reconnecting a few seconds later? Maybe it suddenly switches to mobile data, drops the connection when you move around your home, or stays connected for a few minutes before Wi-Fi disappears again.
The problem can come from weak Wi-Fi signal, temporary Android network glitches, corrupted saved network settings, automatic network switching, third-party apps, or the router itself.
This guide explains how to fix Android Wi-Fi that keeps disconnecting, starting with the quickest and safest fixes before moving to network resets and router troubleshooting.
Quick answer: Restart your phone and router first. If Wi-Fi still disconnects, forget the network and reconnect, test another Wi-Fi network, check automatic network switching, disable VPNs temporarily, install updates, and finally reset your Wi-Fi/network settings.
First: Is It Your Phone or the Wi-Fi Network?
Before changing a lot of settings, figure out whether the problem follows your Android phone or only happens on one Wi-Fi network.
- Only your Android phone disconnects: The phone, its settings, or an installed app is more likely responsible.
- Several devices disconnect from the same Wi-Fi: Focus on the router, modem, internet provider, or Wi-Fi coverage.
- Your Android disconnects from every Wi-Fi network: The phone itself becomes more likely to be the cause.
- Your phone works normally on other Wi-Fi networks: Your home router or network configuration is probably responsible.
- Wi-Fi stays connected but websites do not load: You may have an internet connection problem rather than a Wi-Fi disconnection problem.
Google recommends testing another device on the same network and testing the affected phone on another Wi-Fi network when isolating Wi-Fi problems. See Google's official Wi-Fi troubleshooting guide for its current diagnostic process.
If your Wi-Fi icon remains visible but apps and websites say there is no internet, use our Wi-Fi connected but no internet on Android guide instead.
1. Turn Wi-Fi Off and Back On
Start with the simplest fix.
- Swipe down from the top of your screen to open Quick Settings.
- Turn Wi-Fi off.
- Wait about 10 seconds.
- Turn Wi-Fi back on.
- Reconnect to your network if necessary.
You can also briefly turn Airplane mode on and then off again. This forces the phone's wireless connections to reconnect.
Google includes toggling Wi-Fi and checking Airplane mode among its first troubleshooting steps for Pixel Wi-Fi problems.
2. Restart Your Android Phone
If toggling Wi-Fi does not help, restart the phone.
A restart reloads Android's networking services and can clear temporary connection problems without deleting any data.
- Open your phone's power menu.
- Tap Restart.
- Wait for Android to start completely.
- Reconnect to Wi-Fi.
- Test the connection for several minutes.
The way you open the power menu varies between Samsung Galaxy, Google Pixel, Motorola, OnePlus, Xiaomi, and other Android phones.
3. Restart Your Router
If restarting the phone does not fix the problem, restart your router and modem.
- Unplug the router from power.
- If you have a separate modem, unplug that too.
- Wait about 30 seconds.
- Reconnect the modem first if it is separate.
- Reconnect the router.
- Wait a few minutes for the internet connection to return.
- Reconnect your Android phone and test Wi-Fi.
Google's current Android internet troubleshooting guide recommends power-cycling the router when Wi-Fi connection problems continue.
Do not press the physical Reset button on your router. That may restore factory settings and erase your Wi-Fi configuration. For this step, simply unplugging and reconnecting power is enough.
If all your devices connect to the router but none can access the internet, follow our router connected but no internet troubleshooting guide.
4. Check Wi-Fi Signal Strength
Weak signal is one of the most common reasons Wi-Fi appears to disconnect and reconnect.
Move your phone close to the router and test the connection again.
If Wi-Fi becomes stable near the router but starts disconnecting when you move farther away, you are probably dealing with a coverage problem rather than an Android software problem.
Try these improvements:
- Move the router to a more central and open location.
- Avoid placing the router inside cabinets or behind large furniture.
- Keep the router away from large metal objects.
- Reposition mesh Wi-Fi nodes or extenders.
- Test both 2.4 GHz and 5 GHz Wi-Fi if your router provides separate network names.
2.4 GHz generally reaches farther, while 5 GHz can provide faster speeds at shorter distances.
Google also recommends moving closer to the router when troubleshooting weak Wi-Fi connections.
5. Forget the Wi-Fi Network and Reconnect
If Android has incorrect or corrupted saved information for the network, deleting that saved connection and creating it again can fix repeated disconnections.
On many Android phones:
- Open Settings.
- Tap Network & internet, Connections, or the equivalent menu.
- Tap Internet or Wi-Fi.
- Select your Wi-Fi network or tap the settings icon beside it.
- Tap Forget.
- Select the network again.
- Enter the Wi-Fi password.
- Tap Connect.
Important: Make sure you know the Wi-Fi password before forgetting the network.
Google explains how to manage and remove saved Android networks in its official Android Wi-Fi guide.
6. Check Automatic Network Switching
Your phone may sometimes appear to be disconnecting from Wi-Fi when Android is actually switching to mobile data because it believes the Wi-Fi connection is unstable.
If Wi-Fi disappears and 4G, LTE, or 5G immediately appears, check your phone's automatic switching features.
Samsung Galaxy
On current Samsung Galaxy software, check:
- Open Settings.
- Tap Connections.
- Tap Wi-Fi.
- Tap the three-dot menu.
- Tap Intelligent Wi-Fi.
- Find Switch to mobile data.
Samsung says this option allows a Galaxy device to switch to cellular data when the Wi-Fi connection becomes unstable and switch back when Wi-Fi improves.
You can temporarily disable it while troubleshooting. Samsung documents this feature in its official Galaxy connection settings guide.
Some Galaxy phones also include options such as Switch to better Wi-Fi networks and Turn Wi-Fi on/off automatically. Availability can vary by model and carrier.
Other Android phones
Other manufacturers may use names such as:
- Adaptive Connectivity
- Switch to mobile data
- Auto network switch
- Smart Wi-Fi
- Wi-Fi Assistant
Do not permanently disable useful connectivity features unless testing shows they are causing your problem.
If your phone switches to cellular but mobile data also does not work correctly, see our mobile data not working despite full signal guide.
7. Disable VPNs and Test for Problem Apps
A VPN, security app, firewall, ad blocker, or other networking app can sometimes interfere with internet traffic and make a connection problem look like a Wi-Fi problem.
If you use a VPN:
- Disconnect the VPN temporarily.
- Use Wi-Fi normally for a few minutes.
- Check whether the disconnections stop.
If the issue began after installing or updating an app, Safe Mode can also help identify whether a downloaded app is involved.
Google recommends using Safe Mode when troubleshooting whether a downloaded app is causing Wi-Fi problems on Pixel phones.
The steps for entering Safe Mode differ between Android manufacturers, so follow the instructions provided by your phone manufacturer.
If Wi-Fi works normally in Safe Mode but starts disconnecting again in normal mode, uninstall recently installed or recently updated apps one at a time until you identify the problem.
8. Update Android and Your Apps
Software updates can contain networking, stability, security, and compatibility fixes.
Check for an Android system update:
- Open Settings.
- Open System, Software update, or the equivalent menu for your phone.
- Check for available updates.
- Install any stable update offered for your device.
- Restart the phone if required.
Google also recommends checking for the latest system update as part of its Wi-Fi troubleshooting process.
You should also update important networking-related apps such as VPN clients if you use them.
9. Reset Wi-Fi and Network Settings
If Wi-Fi continues disconnecting on multiple networks, resetting your wireless settings is one of the strongest fixes you can try before considering more drastic options.
Warning: A Wi-Fi/network reset can remove saved Wi-Fi networks and passwords and may remove Bluetooth pairings. Make sure you know important Wi-Fi passwords before proceeding.
Google Pixel
Google currently documents this path:
- Open Settings.
- Tap System.
- Tap Reset options.
- Tap Reset Bluetooth & Wi-Fi.
- Tap Reset settings.
You can verify the latest Pixel procedure in Google's official Pixel Wi-Fi troubleshooting instructions.
Samsung Galaxy
Samsung's current support instructions use:
- Open Settings.
- Tap General management.
- Tap Reset.
- Tap Reset Wi-Fi and Bluetooth settings.
- Tap Reset settings.
- Confirm if requested.
Samsung provides its current troubleshooting procedure in the official Galaxy Wi-Fi connection troubleshooting guide.
Menu wording can change slightly between models and software versions, so search Settings for Reset Wi-Fi or Reset network if you cannot find the option.
10. Troubleshoot the Router
If your Android phone works perfectly on other Wi-Fi networks but keeps disconnecting from your home network, stop resetting the phone and focus on the router.
Try these checks:
- Restart the router.
- Check for router firmware updates.
- Test the phone close to the router.
- Temporarily disconnect Wi-Fi extenders or extra access points.
- Test 2.4 GHz and 5 GHz separately if possible.
- Check whether other devices also disconnect.
- Undo recent changes to router security or Wi-Fi settings.
Check mesh Wi-Fi and extenders
If you use a mesh system or Wi-Fi extenders, your phone may be moving between access points as you walk through the house.
Temporarily test the connection close to the main router with additional access points disabled. If the connection becomes stable, the issue may involve roaming or placement of the mesh nodes.
Test different Wi-Fi bands
If your router provides separate 2.4 GHz and 5 GHz network names, connect to each one separately.
If one stays stable and the other repeatedly disconnects, that gives you a useful clue about signal strength, interference, or router configuration.
Change only one router setting at a time, then test before changing anything else.
Avoid lowering Wi-Fi security simply to fix a connection problem. If you need to modify advanced settings, use your router manufacturer's official instructions.
Samsung Galaxy Wi-Fi Keeps Disconnecting
If your Samsung Galaxy keeps losing Wi-Fi, try this order:
- Turn Wi-Fi off and back on.
- Restart the Galaxy phone.
- Restart the router.
- Go to Settings > Connections > Wi-Fi.
- Forget the affected network and reconnect.
- Open Intelligent Wi-Fi and temporarily test with Switch to mobile data disabled.
- Install available Galaxy software updates.
- Reset Wi-Fi and Bluetooth settings if the problem continues.
Samsung's current Intelligent Wi-Fi settings can also show features such as switching to better Wi-Fi networks, automatically turning Wi-Fi on or off, and displaying network quality information.
Because options vary by Galaxy model and carrier, do not worry if every setting listed here is not available on your phone.
Google Pixel Wi-Fi Keeps Disconnecting
Google's current Pixel troubleshooting process includes:
- Turn Wi-Fi off and back on.
- Make sure Airplane mode is off.
- Restart the Pixel.
- Test another device on the same Wi-Fi network.
- Test your Pixel on another Wi-Fi network.
- Forget and reconnect to the network.
- Restart the router and modem.
- Test Safe Mode for downloaded app conflicts.
- Reset Bluetooth and Wi-Fi settings.
- Check for system updates.
If your Pixel disconnects from several unrelated Wi-Fi networks after trying all of those steps, the phone deserves more attention than the router.
Why Does Wi-Fi Disconnect When the Phone Is Idle?
If you mainly notice the problem after locking your phone, first confirm whether Wi-Fi actually disconnected.
Check whether:
- The phone switched to mobile data.
- A VPN disconnected.
- Battery-saving features affected a networking app.
- The router dropped idle devices.
- The issue also occurs on another Wi-Fi network.
Older Android tutorials sometimes recommend changing a setting called Keep Wi-Fi on during sleep. That option is not available in the same form on many modern Android phones, so avoid following outdated menu paths that do not exist on your device.
What If Wi-Fi Still Keeps Disconnecting?
If none of the fixes worked, use the pattern of the problem to decide your next step.
Wi-Fi only disconnects at home
The router, modem, Wi-Fi coverage, mesh system, or internet provider is more likely responsible.
Contact your router manufacturer or internet provider if several devices are experiencing the same problem.
Your Android disconnects from every Wi-Fi network
If the phone cannot maintain a stable connection on completely different networks, contact the phone manufacturer's support service.
This is especially important if Wi-Fi will not turn on, repeatedly turns itself off, or Bluetooth is also malfunctioning.
The problem started after an Android update
Check for another available system update and your manufacturer's official support information.
Avoid factory resetting the phone immediately. Network troubleshooting and manufacturer support should come first.
Should you factory reset Android?
A factory reset should be a last resort because it erases your personal data and requires you to set up the device again.
Before considering one, make sure you have already:
- Restarted the phone and router.
- Forgotten and reconnected to Wi-Fi.
- Tested another Wi-Fi network.
- Tested without a VPN.
- Checked for problem apps.
- Installed software updates.
- Reset Wi-Fi/network settings.
Frequently Asked Questions
Why does my Android keep disconnecting from Wi-Fi?
Common causes include weak Wi-Fi signal, temporary network glitches, corrupted saved network settings, automatic switching to mobile data, VPN or third-party app problems, outdated software, or problems with the router.
Why does my Wi-Fi keep disconnecting and reconnecting?
The phone may be losing the router's signal, switching between Wi-Fi access points, reconnecting to a saved network, or temporarily moving to mobile data when Wi-Fi becomes unstable.

A VPN can interfere with network traffic or create symptoms that resemble a Wi-Fi problem. Temporarily disconnect the VPN during troubleshooting to see whether the connection becomes stable.
Should I factory reset my phone because Wi-Fi keeps disconnecting?
Not initially. A factory reset should come after simpler troubleshooting because it erases your data. Test other networks, reset Wi-Fi settings, check apps, update Android, and contact support first.
Final Thoughts
If your Android Wi-Fi keeps disconnecting, start with the easy fixes instead of immediately resetting your phone.
Turn Wi-Fi off and back on, restart the phone and router, move closer to the router, forget and reconnect to the network, and test your phone on another Wi-Fi connection.
If the problem follows your phone everywhere, focus on apps, software updates, and network settings. If it only happens on one Wi-Fi network, focus on the router, Wi-Fi coverage, or internet provider.
Following that order helps you identify the actual cause without unnecessarily deleting data or changing router settings that were already working correctly.
