AD-HOC mode  What is it? + How to configure them ▷ 2020

You probably use a daily at home and at work or study a AD HOC network, but you know her by another name. This type of network allows you go online and share information with other connected devices.

AD HOC networks are characterized by being decentralized structures that do not need other computers to exchange data or surf the Internet. In the following paragraphs you can find information about these structures.

Further, We will talk about the benefits of using them and the security problems that you may face. Learn the steps to configure them on any computer.

What is AD HOC mode in wireless networks and what is it for?

What is AD HOC mode in wireless networks and what is it for?

AD HOC mode It is a network structure characterized by having all devices connected to each other through a chain, without having to depend on a specific or centralized infrastructure.

This means that each team can associate freely and share the same hierarchical status, even if new devices are incorporated (which will have the same range and freedom as the existing nodes). This type of decentralized network refers especially to wireless, also calls with the standard IEEE 802.11 of the Institute of Electrical and Electronic Engineers.

What are the benefits of using AD HOC networks at home or office?

Among the most outstanding benefits that the AD HOC networks we can mention that different nodes can share information with each other, without having the need to request authorization from another team. Nor should it transmit the data packets by any special computer. In this way, a agility important within the decentralized structure so that no router or access point needed.

No need for cabling to create a network of this type. This makes the installation costs very low compared to other networks, allowing the incorporation and exit of other participants in a fast way.

The latter also generates that configuration is minimal, so it is not necessary to have advanced computer knowledge to belong to a AD HOC network. Another outstanding benefit is the coverage area. Which is relatively wide, being able to improve it with simple steps through repeaters.

Security in AD-HOC Networks How safe is it to use these networks?

To belong to a AD HOC network It is necessary to enter through an access point, which usually has an entry password. This means that Any hacker who cracks the security PIN will be able to gain access and be part of the network.

In this network, each node It runs its own system of intrusion detection protocols, so the security level of the entire network can fail, causing the hacker to enter any computer and intercept the data packets. Therefore, we can say that the level of security offered by wireless networks is relatively low.

Learn how to configure a fast and easy AD-HOC network on the main operating systems

Anytime configure an AD-HOC network You will have to follow the steps that we will show you below, which will depend on the operating system you have on your computer.

Let’s see how you should proceed in each case:

On windows

The steps that you must carry out in Windows are the following:

  • Click on the Start button and type “Cmd”. This will make the application run “Symbol of the system”.
  • When you see the pop-up window, right click on the option “Symbol of the system”and choose to run as administrator.
  • Then enter the command “Netsh wlan show drivers” to know the network interface.
  • Writes “Netsh wlan set = allow ssid = password = .
  • Run the command “Netsh wlan start hostnetwork” to start the network.

At this time you will have to go to the Control Panel and follow this guide:

  • Select option “Network and Internet”.
  • Click on “Center network and sharing”.
  • Choose the option “Change adapter settings” by clicking on it.
  • A pop-up window will appear with the different network connections. Choose “Internet connection sharing” and look for the web you just created.
  • Press the right mouse button and choose the tool the device connected to Wifi.
  • Select the tab “Share”.
  • Activate the option “Allow other network users to connect through this computer’s Internet connection” and select the network AD HOC created.
  • If you want to know the IP of the connection, double click on the option “TCP / IPv4 Properties” and then choose “Networks”.

On linux

When you have a Linux computer you should follow this step by step:

  • Open the command line and enter $ iwconfig wlan0 mode Ad-Hoc.
  • Then write $ iwconfig wlan0 essid .
  • Enter a password to increase security. For this, you will have to run $ iwconfig wlan0 key s: .
  • Finally, type the command $ ifconfig wlan0 ip.ip.ip.ip netmask .

On macOS

On a Mac, you will do the following:

  • Go to the tool “System preferences”.
  • Select option “Share”.
  • Then in the pop-up window choose “Share internet”.
  • Unfold the box “Share the connection of:” and choose “Ethernet”.
  • In “The use of computers to:”, you will have to select “Wifi”.
  • Then, you will have to click on “WiFi options”.
  • Write the name of the AD HOC network, the frequency channel and the security type.
  • Click on “Start”.
