Select “Restart” from the options that appear.

Toggle Airplane Mode:

Swipe down from the top of the screen to open the notification panel.
Tap on the Airplane Mode icon to turn it on.
Wait for a few seconds, then tap on the Airplane Mode icon again to turn it off.

Forget and reconnect to Wi-Fi:

Go to the Settings menu on your Android device.
Select “Wi-Fi” or “Network & Internet” depending on your device.
Tap and hold on the Wi-Fi network you are connected to.
Select “Forget network” or “Forget” from the options that appear.
Reconnect to the Wi-Fi network by tapping on it and entering the password if required.

Restart your router:

Locate your router and unplug it from the power source.
Wait for about 10 seconds.
Plug the router back into the power source.
Wait for the router to fully restart.

Check network settings:

Go to the Settings menu on your Android device.
Select “Wi-Fi” or “Network & Internet” depending on your device.
Tap on the network you are connected to.
Ensure that the settings such as IP address, gateway, and DNS are set to obtain automatically.

Check mobile data & data connection

To check your mobile data and data connection on your device, follow these steps:

1. For iPhone users, go to “Settings” and tap on “Cellular” to ensure that the data is turned on. For Android users, go to “Settings” and tap on “Network & internet” or “Connections” to check if your mobile data is enabled.

2. If your device still doesn’t connect to the internet, try toggling the airplane mode on and off. This can help reset the connection.

3. Check if your Wi-Fi is turned on. If it is, try disconnecting and reconnecting to your Wi-Fi network.

4. Ensure that your SIM card is properly inserted and not damaged. Sometimes, removing and reinserting the SIM card can resolve connection issues.

5. If you’re using a laptop or computer, make sure your Wi-Fi is turned on and you’re connected to a stable network.

python import os


def check_network(ip_address):

    response = os.system("ping -c 1 " + ip_address)

    if response == 0:

        print(f"Network is reachable. IP: {ip_address}")

    else:

        print(f"Network is unreachable. IP: {ip_address}")

# Example usage: check_network("192.168.1.1")

The above code snippet uses the `ping` command to check if a specific IP address is reachable. It sends a single ping packet to the given IP address and prints whether the network is reachable or unreachable. You can modify and expand this code according to your specific requirements.

However, keep in mind that this is just a basic demonstration and may not be suitable for fixing complex network issues. It is always recommended to consult a network professional or refer to official documentation for comprehensive troubleshooting and network maintenance.

Turn airplane mode on & off

To turn airplane mode on or off on your device, follow these steps:

1. For Windows: Click on the network icon in the taskbar, then click on “Airplane mode” to toggle it on or off.

Bypass Your DNS Server

If you’re experiencing network connection problems and suspect that your DNS server is the issue, you can bypass it to troubleshoot the problem. To do this, follow these steps:

1. On your Windows computer, open the Control Panel.
2. Look for the “Network and Internet” category and click on it.
3. Select “Network and Sharing Center” from the options.
4. On the left-hand side, click on “Change adapter settings.”
