3. Summary
Configuring the router's Telnet login is not too difficult, because the instructions are relatively single, but there are still some small details that deserve our attention. First, we should note that the Telnet client is turned on in the control Panel , otherwise it may not log on to telnet. Second, configuring Telnet requires only input instructions, but test connectivity is required to be entered on the specified PC connected to the enclosure . Finally, note that when setting the login password, be sure to enter the command login activation password. In general, you can successfully configure the router's Telnet login as long as the details are handled properly .
