Appendix A – Troubleshooting and FAQs

The following section explains how to use Telnet terminal commands to diagnose your network problems via the built-in debug tool. Our examples use Windows Telnet client software. If you are a Mac user, you should install third-party Telnet client software on your computer. By default, the Linux has a built-in Telnet client.

Using the Telnet Terminal Commands

Click Start → Run and type Telnet 192.168.0.1 in the Open box as below. Note that the IP address in the example is the default address of the Router. If you have changed the default, enter the current IP address of the router.

Click OK. The Telnet terminal will open. If an administrator password has not been assigned, follow the on-screen instructions to assign one.

After assigning a password, type a question mark (?). You will see all the possible Telnet commands.
