How to check internet connection?

You can check your internet connection using several methods. Here are a few common ways:

1. Ping a Website: You can use the ping command to check connectivity to a specific website. For example, to ping Google, you can run:

   ping -c 4 google.com

   This command sends 4 packets to Google and shows you the response time.

2. Check with Curl: If you have curl installed, you can check connectivity by trying to fetch a webpage:

   curl -I https://www.google.com

   This command will return the HTTP headers if the connection is successful.

3. Using wget: Similar to curl, you can use wget to check connectivity:

   wget --spider https://www.google.com

   This command checks if the URL is reachable without downloading the page.

4. Check Network Configuration: You can also check your network configuration with:

   ifconfig

   or

   ip a

   This will show you the network interfaces and their statuses.

5. Check Default Gateway: You can check if you can reach your router or gateway:

   ping -c 4 <your_gateway_ip>

   Replace <your_gateway_ip> with the IP address of your router (commonly 192.168.1.1 or 192.168.0.1).

If any of these commands return successful responses, your internet connection is likely working. If you encounter errors, there may be an issue with your network configuration or connection.
