Although many of us use the Windows system on a daily basis by virtue of the fact that it is the most widespread system, we always discover more secrets that have always been present in the system but may not be realized by many, besides the many features and settings of the Windows system there is a list of some advanced additional features that are not It is enabled by default, such as the "Sandbox" feature, as well as the "Hyber-V" feature for simulating systems and the "Application Defender" feature, which are the features that we have all highlighted in previous topics.
Today, we will shed light on a new feature of the additional Windows system features called "Telnet". We will learn together through the lines of today's article about the benefit of that feature and how to activate and use it within the Windows system in addition to how to control the network's router through it.
What is the "Telnet" feature?
"Telnet" is a protocol used to establish a connection between two remote devices, so that the user on one of the "Client" devices can control the other "Server" device as if he were actually using it, but through a command execution interface and not a software user interface.
Telnet is a very old protocol that was used by system administrators in places such as companies and universities and even in home networks to control computers on the network and also to remotely control the settings of the same network devices such as the network router or any other device, whether a switch or an Access Point inside That network instead of going where the device is located and connecting to it for real.
Not only that, but you can also, through the protocol, control devices remotely via the Internet, i.e. outside the scope of the local network, for example site administrators can communicate through the protocol to the server address of the site remotely and enter the server's login data to change settings and fully control the server in addition to solving problems Tele-tech.
In general, you can consider the "Telnet" protocol is the old and first version of remote control programs that are used to establish a remote connection between two devices, which we currently use to solve technical problems or for other purposes such as educational purposes. The most famous of these programs is the "Team Viewer" program and Any Desk.
But why is using "Telnet" not so familiar today?
Indeed, the use of the protocol has been largely restricted at the present time and this is due to two main reasons, the first of which is that the protocol is simple and very old and therefore it is considered insecure when establishing a connection between two devices remotely over the Internet as the protocol does not use any system to encrypt data over the connection and thus any programs can Listen to the capture of data between the two devices, and you will find that this data is a normal text that is not encrypted at all. Therefore, all data resulting from this connection will be obtained, including any private information such as login data.
The second reason, and as we mentioned earlier, is that "Telnet" is a set of commands that are executed through the environment of the "cmd" command prompt or the latest version "Powershell" and therefore some may not prefer to use it, especially in the presence of other programs with a user interface such as "Team Viewer" because Certainly more accessible.
So what might we be using "Telnet" at the moment?
The best use of "Telnet" at the present time will be in the internal network to control and establish a connection with other computers or even communication with the router itself and control it, displaying information about the router or any other devices on the network and many other wonderful things that we will explain in the next lines.
Activate the "Telnet" feature of the Windows system
The "Telnet" protocol is activated by default within the Windows XP version, but from the version of Windows Vista to Windows 10 you will find "Telnet" as an additional feature that you can activate by heading to "Control Panel" and clicking on the option "Turn windows features on or off" and then Activate the "Telnet Client" option to control your device with other devices.
You can also activate the "Telnet Server" option to control this device through another device, which is what we will devote to a separate article in the future, but it must be made clear that this option specifically will not be found in the Windows 10 version while you will find it in previous versions.
You can also easily execute the following command from the command prompt "cmd" or "Powershell", which will activate the "Telnet Client" feature on the system directly:
dism /online /Enable-Feature /FeatureName:TelnetClient

How to control the router via "Telnet"
After activating the "Telnet Client" feature on your device, as we explained with the previous steps, you can easily control the router of the internal network via "Telnet", just go to the command prompt, either "cmd" or "PowerShell" and run one of them as an administrator, then you can connect to the router simply by typing The following command, of course, replacing "ip-address" with the router's IP address, which is usually 192.168.1.1:
telnet ip-address
If a successful connection is established, you will find the word "Password" on the screen, which means entering the password to enter the router, type it and press "enter" and you will find that the name of the router manufacturer has been written with the command prompt indicator, which means that a connection has been established with the router. The router is ready to receive commands.
Initially, you can explore the commands that can be executed on the router by typing the? To help and display the commands, it should also be clarified that most of the commands need to write additional commands next to them. Therefore, when writing any command individually, you may get an "incomplete command" error. Therefore, type the command then a space and then a mark? To know its additional commands, one of which must be written after the main command.
For example, by typing the "show all" command, you can display all the information about the router, such as how to specify the IP addresses in the network, as well as the active communication channels of the router and whether there is more than one wireless network or not.
Also, by using the "sys" commands, you can find out information about the router such as the system version of the router through the "sys version" command, in addition to a very useful command through which you can restart the router remotely, which is the "sys reboot" command.You can also turn on or off the wireless network in the router by using the “rt enableap” command to turn on the “Wi-Fi” wireless router connection or the “rt disableap” command to turn off the wireless network in the router. You can also use the “rt” command followed by the “?” To know the sub-commands that you can apply through this command.
You can also display detailed information about the wireless network through the "rtwlan" command. The most important sub-commands under this command is the "rtwlan rtdisp" command, which displays all information about the wireless network, including the network name, the address of the "mac address" of the router, and many advanced information.
You can also use the "wan" command to find out information about your network's Internet connection. For example, you can use the following command to find out the current download and upload speed of the Internet connection:You can also use the following command to find out the status of the Internet connection and whether it is working or not:wan adsl status
You can also use the following command to find out some information about the Internet connection, most notably "up time", which is the number of hours the router has worked continuously since the last operation or restart of the router:
wan adsl perfdata
Of course, this is not all that you can do, but these are just examples of commands that you can implement and so that we can easily communicate the idea of work, but of course you can explore more commands that you can use through the help command "?" Behind any command you want to know how to use it and know the additional commands that it needs.
