How to create a WiFi access point in Ubuntu 18.04 LTS?

Those readers who are Windows users or who have been migrating of this system they will know that, for a long time In Windows, it was possible to use a wireless network adapter to share an Internet connection with other computers.

Generally, This is done by creating a "Hotspot", or an "ad-hoc", which is issued directly from the wireless network adapter. It's very easy to do, and it's a feature that many Windows users like.

On Linux, streaming from an access point has not always been easy. Until recently, users had to manually enter on the command line, bridged adapters together, set IPtables, and so on.

El Being able to create a Hotspot is the easiest way to share the Internet connection through Ethernet connection from computer to wireless devices such as smartphones and tablets.

En the new versions of Ubuntu (and network manager), make connections can be shared through access points it can be done just as easily as it can be done on other operating systems.

To enable this option you need to convert the first wireless network of your laptop into a Wi-Fi Hotspot or even with a USB or PCI Wi-Fi card in your computer and then connect the devices to the WiFi access point that they have created.

Steps to create a Hotspot (WiFi access point) in Ubuntu 18.04 LTS

With GNOME 3.28 as the desktop environment in Ubuntu 18.04 LTS, WiFi tethering on the system is really easy to do.

The first step in creating a new wireless network is go to the network icon on the Ubuntu taskbar and click on it:

Here we are going to click on "Wifi options"

Esto takes us to the "Network Connections" window

Here we are going to click on create the new connection by clicking on the winged icon of the cone that we see in the image and we are going to click on "Activate Wifi Hotspot".

Si you want to change the name (SSID) and password from the access point, open the Network Connections editing tool, to do this, just open a terminal on the system with Ctrl + Alt + T and run in it:

nm-connection-editor

Here A new sale will open where we must double click in hotspot and we will be allowed to change the name of the access point, as well as the password.

Followed by "band" mode. This setting enables wireless network broadcasting on different frequencies.

There are two options from which we can choose if we know what to do, which are 5 GHz and 2 GHz mode.

The 5 Ghz (A) connection mode allows faster download speeds, but with a shorter connecting range.

Here you should select this option if you already know that it is possible to connect to the 5 GHz connections on the computer that is used to establish this access point.

If not, select the 2 GHz (B / G) mode in band mode, although the recommended option if you do not know what to do is to leave it on automatic.

The last setting that has to be adjusted so that this access point can be accessed is "device".

This zone counts the hotspot network and which device should be used to transmit.

Using the drop down menu, select your wireless chip. Also here we can assign some custom values, either way we want it to use a static or dynamic IP or use a proxy.

To start streaming, click the "Save" button.

It should be noted that the access point will not work unless you have a cable connection that has the Internet to share over the network.

The access point tool automatically detects a wired connection and shares it through the WiFi access point.

Without further ado, I hope this little tutorial is useful for you.
