- Tap Connect
Wait 5-10 seconds for the connection to establish. This solution resolves many connection issues caused by corrupted network configurations.
Solution 6: Restart Your WiFi Router
Sometimes the issue isn’t your phone—your router may need restarting.
How to Restart Your Router:
- Locate the power cable on the back or side of your router
- Unplug the power cable from the outlet
- Wait 30 seconds—this allows the router to fully power down
- Plug the power cable back in
- Wait 1-2 minutes for the router to fully restart and reconnect
The lights on the router will go dark during shutdown, then illuminate as it restarts. Once the lights stabilize, try reconnecting your Android device.
Alternative: If your router has a physical power button, press and hold it for 10 seconds to power down, wait 30 seconds, then press it again to power on.
Solution 7: Verify the Correct Password
Connection failures often result from incorrect WiFi passwords.
How to Check Your Password:
- Default WiFi credentials are printed on your router’s label (usually on the back or bottom)
- Check any documentation provided with your router
- Log in to your router’s admin panel (typically at 192.168.1.1) to view or change the password
Password Entry Tips:
WiFi passwords are case-sensitive, meaning capital and lowercase letters matter. Enter the password exactly as specified, including special characters.
If you’re unsure of the password, reset your router to factory settings (consult your router’s manual for instructions), which resets the password to the default printed on the label.
Solution 8: Reset Network Settings
If multiple WiFi networks cause problems or previous solutions haven’t worked, resetting network settings provides a comprehensive reset.
Important Warning: Resetting network settings removes all saved WiFi networks and passwords—you’ll need to reconnect manually, so write down your WiFi password first.
How to Reset Network Settings:
For Most Android Devices:
- Open Settings
- Navigate to System or General Management
- Tap Reset or Reset Options
- Select Reset Wi-Fi, Mobile & Bluetooth or Reset Network Settings
- Tap Reset to confirm
For Samsung Devices:
- Go to Settings
- Tap General Management
- Select Reset
- Tap Reset Network Settings
