It is likely that you use daily at home and at work or study a AD HOC networkbut you know her by another name. This type of network allows you access the Internet and share information with other connected devices.
AD HOC are characterized by being decentralized structures that do not need other computers to exchange data or surf the Internet. In the following paragraphs you will find information about these structures.
Also, We will talk about the benefits of using them and the security problems 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?
AD HOC mode It is a network structure that is 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 added (which will have the same range and freedom as existing nodes). This type of decentralized networks refers especially to wirelessalso called 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 to request authorization from another team. Nor should it transmit the data packets through some special computer. In this way, one achieves agility important within the decentralized structure, so no router or access point needed.
No cabling required to create a network of this type. This means that the installation costs are very low compared to other networks, allowing the incorporation and exit of other participants quickly.
The latter also generates configuration is minimalso it is not necessary to have advanced computer knowledge to belong to a AD HOC network. Another notable benefit is the coverage area. Which is relatively wide, being able to improve it with simple steps through repeaters.
AD-HOC Network Security 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 access and become 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, allowing the hacker to break into 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 an AD-HOC network easily and quickly in the main operating systems
Whenever you want 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 perform 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 popup window right click on the option “Symbol of the system”and choose run as administrator.
- Next, enter the command “netsh wlan show drivers” to know the network interface.
- Write “netsh wlan set
mode=allow ssid=key= .” - 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 the option “Network and Internet”.
- Click on “Center network and sharing”.
- Choose the option “Change adapter settings” clicking on it.
- A pop-up window will be displayed 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 .
- 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’ll do the following:
- Go to the tool “System preferences”.
- Select the option “Share”.
- Then in the popup 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 type of security.
- Click on “Start”.
