Is your Android phone refusing to connect to WiFi, disconnecting randomly, or showing “Connected, no internet”? You’re not alone. WiFi issues are common on Android devices due to software bugs, router problems, signal interference, or even simple misconfigurations.
The good news is that most WiFi problems have simple fixes. In this guide, you’ll learn the top reasons why Android WiFi stops working and 10 proven methods to get your connection back fast.
1. Restart Your Phone and WiFi Router
This is the simplest and most effective fix for most WiFi issues. Restarting your Android clears temporary glitches, and restarting the router resets the internet signal.
How to fix it:
- Restart your Android phone
- Turn off your router for 15 seconds
- Turn it back on and wait for the lights to stabilize
If the WiFi connects normally after this, the issue was temporary system or router failure.
2. Toggle WiFi, Airplane Mode, and Mobile Data
Android sometimes gets stuck switching between data and WiFi. Toggling these settings can refresh the connection instantly.
Try this:
- Turn on Airplane Mode for 10 seconds
- Turn it off again
- Disable and re-enable WiFi
- Turn off mobile data so WiFi becomes the priority
This refreshes your phone’s wireless antennas and often restores the network.
3. Forget the WiFi Network and Reconnect
Saved WiFi settings can become corrupted, causing connection failures or incorrect passwords.
Fix:
- Open Settings → WiFi
- Tap your network name
- Select Forget
- Reconnect by entering the password again
This rebuilds the connection from scratch.
4. Check if WiFi Works on Other Devices
If other devices (laptop, tablet, another phone) can connect to the same WiFi network, the problem is with your Android phone — not the router.
If WiFi works on other devices:
Your phone settings or software are causing the issue.
If WiFi does NOT work on any device:
The router or internet provider is the problem.
5. Check Router Distance and Signal Strength
Weak signal causes slow internet, frequent disconnections, or “Connected but no internet.” Walls, floors, and electronic devices can interfere with WiFi.
To improve signal:
- Move closer to the router
- Avoid obstacles like walls and metal objects
- Keep your router elevated (not on the ground)
- Avoid using the microwave or Bluetooth devices nearby
Even a small increase in signal strength can fix connection issues.
6. Check for Android System or App Bugs
Sometimes a system update, app bug, or corrupted file breaks WiFi connectivity.
Fix:
- Update your Android system in Settings → Software Update
- Update apps in Google Play Store
- Restart the phone after updating
Updates often patch WiFi bugs and restore stability.
7. Disable VPN or Proxy Settings
VPN apps and proxy settings can block your WiFi connection or slow it down dramatically.
To fix:
- Turn off any VPN apps
- Go to Settings → Network → Advanced
- Disable any Proxy settings
If WiFi works after disabling VPN, then the VPN was the cause.
8. Reset Network Settings
If nothing is working, your phone’s network configuration may be corrupted. Resetting network settings restores everything to default.
Steps:
- Go to Settings → System
- Tap Reset Options
- Tap Reset WiFi, Mobile & Bluetooth
This will erase saved WiFi passwords, so be sure you know them before resetting.
9. Check If Your Router Has MAC Filtering Enabled
MAC filtering can block your device from connecting even if the password is correct.
To check:
- Log in to your router admin page (printed on the router)
- Go to Wireless Settings
- Look for “MAC Filtering” or “Access Control”
- Disable it or add your phone’s MAC address to the allowed list
If your phone connects afterward, MAC filtering was blocking you.
10. Factory Reset (Last Resort)
If your Android still can’t connect to WiFi after trying everything, your system may be corrupted or a hidden bug may be causing the issue. A factory reset can solve deep software problems.
Warning:
This erases all data, so back up your files first.
Steps:
- Open Settings → System
- Tap Reset
- Select Factory Reset
After resetting, reconnect to WiFi before installing any apps to test the connection.
When to Visit a Repair Shop
If your WiFi still doesn’t work even after a factory reset, the issue may be hardware-related.
Possible hardware problems include:
- Broken WiFi antenna
- Loose internal connector
- Motherboard damage
- Water exposure
Typical repair prices:
- WiFi antenna repair: €20–€50
- Motherboard repair: €40–€120
Most WiFi problems are fixable and take less than an hour to diagnose.
Final Thoughts
WiFi problems on Android can be frustrating, but in most cases, they’re caused by simple issues like weak signal, router glitches, outdated software, VPN interference, or corrupted network settings. By following the steps in this guide, you can restore your WiFi connection quickly and keep your phone running smoothly.
If the issue continues after trying all the solutions, consider visiting a repair shop for a hardware check. Most hardware-related WiFi issues are affordable to fix.
