How to Troubleshoot Network Issues

The first place you should visit when you run into a network issue is the Command Prompt. We’ve already taken a look at the most important commands for networking, so we’ll summarize two of them here.

First, ipconfig provides information about your current connection. One of the most useful entries here is the IPv4 Address — any address beginning with 169 means that your computer isn’t receiving a valid IP address from your router.

Second, use the ping command to send a few packets of information to a remote server. Add the -t flag and it will continue to ping until you stop it. This is a much more efficient way to check if you’re connected to the internet than refreshing a web page over and over. A good address to ping is — one of Google’s DNS servers.

Typing ping -t will try to reach a Google server every few seconds until you press Ctrl + C to stop the command.
