Android Wi-Fi Keeps Disconnecting Fix: 9 Ways to Stay Connected (2026)
Looking for an Android Wi-Fi keeps disconnecting fix that actually works? Whether it drops every few minutes, cuts out the moment your screen turns off, or bounces to mobile data on its own, this guide walks through the fixes that actually stop it – tested across multiple Android phones.
Success rates below are based on WekyTech’s own testing across Samsung Galaxy, Google Pixel, and Motorola phones running current Android versions.
Is It Your Phone, the Router, or the Wi-Fi Band?
If every device in the house – laptop, tablet, another phone – drops from the same Wi-Fi, the problem is the router, not your Android phone. If only your Android phone disconnects while everything else stays connected, the cause is almost always one of three things: an aggressive battery-saving setting putting the Wi-Fi radio to sleep, a MAC address conflict with your router, or the phone bouncing between the 2.4GHz and 5GHz bands your router offers.
| Symptom | Likely Cause |
|---|---|
| Drops specifically when the screen turns off | Wi-Fi sleep policy or battery optimization |
| Drops every few minutes regardless of screen state | MAC randomization conflict with an older router |
| Switches to mobile data on its own | Android judging the Wi-Fi signal “poor” even when it isn’t |
| Every device in the house drops, not just your phone | Router issue – not your phone |
| Drops only near the edge of your home/office | Weak signal or band-steering between 2.4GHz/5GHz |
| Started right after an update | Reset power-management settings from the update |

| Reset network settings | 30% |
The Complete Android Wi-Fi Keeps Disconnecting Fix List
1. Toggle Airplane Mode
Open Quick Settings, tap Airplane Mode, wait about 10 seconds, then turn it off. This forces a full reset of the Wi-Fi radio’s power state rather than a simple reconnect, and clears a temporary glitch in many cases before you need any deeper fix.
2. Keep Wi-Fi On During Sleep
Android’s default power-saving behavior can suspend the Wi-Fi radio once the screen turns off, breaking active connections like music streaming, file syncing, or messaging. Go to Settings > Network & Internet > Wi-Fi > three-dot menu > Advanced > Wi-Fi when screen is off, and set it to Always.
3. Switch to “Use Device MAC” Instead of Randomized
Android randomizes your phone’s MAC address per network by default for privacy. Some older routers – especially ISP-issued boxes from a few years back – handle this poorly and periodically drop the connection as a result. Go to Settings > Network & Internet > Wi-Fi, tap your saved network, open Privacy, and change it from Use randomized MAC to Use device MAC. Toggle the network off and on once afterward.
4. Forget the Network and Reconnect
A corrupted saved network profile is a common, easy-to-overlook cause. Tap your network under Wi-Fi settings, choose Forget, then search for it again and enter the password fresh.
5. Disable Battery Optimization for Wi-Fi
Aggressive battery management can restrict background network activity even with Wi-Fi technically connected. Go to Settings > Apps > Special app access > Battery optimization, and check whether system-level Wi-Fi or network components are being restricted.
6. Restart the Router
Unplug the router for a full 30 seconds, then plug it back in. If your phone disconnects but a laptop or tablet on the same network stays connected, this step is less likely to help – but if devices disconnect intermittently across the board, this is often the actual fix.
7. Disable or Reconfigure Your VPN
Some VPN apps, especially older or poorly optimized ones, can cause instability by routing traffic through an unstable tunnel. Turn the VPN off and see if the disconnects stop; if they do, check the VPN app’s settings for a “Battery Optimization” or “Kill Switch” feature that may be interfering.
8. Assign a Static IP Address
If your phone is constantly fighting for a new IP address from the router, assigning a static one removes that variable. Under your Wi-Fi network’s settings, look for IP settings and switch from DHCP to Static, then enter an IP address outside your router’s DHCP range (check your router’s admin page for that range first).
9. Reset Network Settings
If nothing above works, a full network reset clears every saved Wi-Fi network, Bluetooth pairing, and mobile data setting, giving your phone’s networking stack a clean slate. Go to Settings > System > Reset Options > Reset Wi-Fi, Mobile & Bluetooth.
When It’s the Router, Not Your Phone
If every device on your network drops – not just your Android phone – stop troubleshooting the phone and focus on the router instead: reboot it, check for a firmware update through the router’s admin page or your ISP’s app, and consider its placement (routers tucked inside cabinets or far from where you use your phone most cause real signal problems that no phone setting can fix).

FAQ
Why does my Android Wi-Fi disconnect when my screen turns off?
By default, Android can suspend the Wi-Fi radio to save battery once the screen is off. Setting “Wi-Fi when screen is off” to Always under Wi-Fi Advanced settings resolves this in most cases.
Does MAC address randomization really cause disconnects?
Yes, on some older routers. Android randomizes your MAC address per network by default for privacy, but older routers can misread this as a new, unauthorized device and drop the connection – switching to “Use device MAC” fixes this.
How do I know if it’s my phone or my router?
Check whether other devices on the same network – a laptop, tablet, or smart TV – also disconnect. If they do, the router is the cause. If only your Android phone drops, the fix is on your end.
Can a VPN cause Wi-Fi to disconnect on Android?
Yes, especially older or poorly optimized VPN apps. Disable the VPN temporarily to test – if disconnects stop, check the VPN app’s battery optimization or kill switch settings.
Will resetting network settings delete my saved Wi-Fi networks?
Yes, a full network reset clears every saved Wi-Fi network and Bluetooth pairing, not just the one causing trouble – you’ll need to reconnect to Wi-Fi and re-pair other devices afterward.
Is a static IP address worth setting up to fix disconnects?
It can help if your phone is repeatedly failing to get an IP address from the router, but it’s a more advanced fix – only attempt it if you’re comfortable with basic networking settings.
