How to Fix Wi-Fi Not Working on Mobile (Top Working Solutions)
Below are the best fixes, explained step-by-step. Try them one by one until your problem is solved.
1.Check Wi-Fi & Airplane Mode Settings
Sometimes the simplest checks fix the biggest issues. Before troubleshooting deeply, ensure:
- Wi-Fi is ON
- Airplane Mode is OFF
- Mobile Data and Hotspot are turned OFF to avoid interference
Steps for Android:
- Swipe down to access Quick Settings
- Toggle Wi-Fi OFF and ON
- Toggle Airplane Mode ON and OFF
- Try connecting again
Steps for iPhone:
- Go to Control Center
- Turn Airplane Mode ON → wait 5 seconds → OFF
- Reconnect Wi-Fi
Why this works:
- Resetting the wireless connection forces your device to search fresh for nearby networks.
If this does not help, move to the next steps.
2. Restart Phone and Router (Most Effective Fix)
Rebooting the system refreshes the network modules and clears temporary glitches.
Steps:
- Turn OFF your mobile and wait 30 seconds
- Restart your Wi-Fi router
- After full reboot, reconnect Wi-Fi
Note:
Make sure router lights (Power, Wi-Fi, Internet) are stable. If the Internet light is red/orange, contact your internet provider.
This single fix solves 70–80% Wi-Fi issues globally.
3. Forget Network and Reconnect Again
A corrupted saved password or Wi-Fi profile can block connectivity. Forget and reconnect.
Steps for Android / iPhone:
- Open Settings → Wi-Fi
- Tap the connected network → Forget
- Turn Wi-Fi off → on again
- Re-enter password
If you changed the router password recently, this step is mandatory.
4. Check Wi-Fi Range and Signal Strength
If you are too far from the router or there are too many walls in between, Wi-Fi may disconnect frequently.
Tips:
- Move closer to the router
- Avoid corners, metal objects, microwave ovens near router
- If using 5GHz band, stay closer (fast but limited range)
If the issue continues only at distance, upgrade to Wi-Fi 6 router for improved coverage.
5. Disable Power Saving Mode / Battery Saver
Battery saver mode limits background networking to save energy.
Steps:
- Turn Off Battery Saver / Low Power Mode
- Disable Adaptive Battery / Smart Saving Mode
- Remove Wi-Fi restrictions from app permissions
Especially if Wi-Fi disconnects automatically when screen is OFF, this setting is the reason!
6. Update Phone Software / Wi-Fi Drivers
Old firmware can cause network bugs.
Steps:
- Settings → System → Software Update
- Install updates and restart device
Updates improve Wi-Fi stability and fix compatibility issues.
7. Reset Network Settings (100% Working Fix)
If nothing else works, reset network settings.
Android:
Settings → System → Reset Options →
➡️ Reset Wi-Fi, Mobile & Bluetooth
iPhone:
Settings → General → Transfer or Reset →
➡️ Reset Network Settings
After reset, reconnect Wi-Fi again.
Note: This will remove saved passwords, VPN settings & paired Bluetooth devices.
8. Check for Too Many Connected Devices
If several users are connected, router may block additional devices or slow down speed.
Solution:
- Disconnect unused devices
- Upgrade your router plan/device if needed
Use Guest Mode for visitors to avoid overload.
9. Change DNS Server for Faster Internet
Sometimes ISP DNS servers are slow or unresponsive. Changing DNS improves browsing.
Recommended DNS:
| DNS Provider | Primary DNS | Secondary DNS |
|---|---|---|
| Google DNS | 8.8.8.8 | 8.8.4.4 |
| Cloudflare | 1.1.1.1 | 1.0.0.1 |
| OpenDNS | 208.67.222.222 | 208.67.220.220 |
Apps like DNS Changer make this easy.
10. Reset Router to Factory Settings (Last Option)
If router settings are damaged, reset is needed.
Steps:
- Press the small Reset hole using a pin for 10–15 seconds
- Re-configure from ISP details
Only do this if you’re comfortable setting up Wi-Fi again.
Wi-Fi Not Working Issues & Solutions (Quick Table)
| Problem | Reason | Solution |
|---|---|---|
| Wi-Fi Connected but No Internet | Router/ISP issue | Restart router, check service status |
| Wi-Fi Not Turning ON | System glitch/hardware failure | Restart phone, factory reset, repair |
| Wi-Fi Disconnecting | Battery saver/weak signal | Turn off battery saver, move closer |
| Slow Wi-Fi | Too many devices, old router | Upgrade plan or router, change DNS |
| Incorrect Password Error | Wrong password saved | Forget & reconnect |
| Wi-Fi Greyed Out | Firmware issue or antenna damage | Update OS or repair device |
Extra Tips to Boost Wi-Fi Performance
- Keep router at a high central location
- Change Wi-Fi channel to reduce interference
- Use 5GHz band for high-speed devices
- Clean Wi-Fi cache using mobile maintenance tools
- Avoid using VPN when unnecessary
- Use mesh Wi-Fi for bigger homes
When Should You Take Your Phone to Service Center?
If any of these signs appear:
- Wi-Fi switch turns off automatically
- Wi-Fi option is greyed out permanently
- Device connects only for a few seconds
- Phone had a drop or water damage recently
This means Wi-Fi hardware module (Antenna/IC) is damaged and needs repair.
