In the last column we see our configuration files which is used by our devices in order to connect to the network. It is simple to understand that our devices by themselves can do nothing.

They need us to make a configuration file to tell them how to achieve network connectivity. As you can see here the files with name starting with ifcfg- interface configuration are connection profiles. When we create a new connection or modify an existing one with nmcli or nmtui , the results are saved here as connection profiles. In the above image you can see the two connections which are active: You can use the auto-complete hitting Tab when you use nmcli, but is better to use minimal format of the command.

Thus, the following commands are equal:. I see that my device enp0s3 took the We can make our first connection profile. The minimum properties we must define are type , ifname and con-name:.

If your card is not supported out of the box, you may need to use ndiswrapper, which will require the Windows drivers fo your card. The post-down command is run after the interface goes down.

There are also post-up and pre-down commands. You could use post-up to mount disks after an interface goes up. This will save you lots of time and frustration. The SSID and password needs to be configured on your wireless router, how to do that is up to the reader. If you have problems coming up with a password, please have a look here. If you are using WEP encryption which is not advised you may skip this step.

The priority in this file determines to which network you will connect if more then 2 configured networks are available. This will always be the network with the highest priority.

Configure laptops for multiple locations When you have a laptop you don't want to configure it to only be able to have a internet connection at only one location.
