How do we change the Wifi properties?
Another of the most relevant things, if you want to have full control, is to know how to change the name of the wifi (name SSID) of the server.
To be able to do it there is a file with the configuration of the parameters where we can change various things. The file is hostapd.conf.
Once we are in the raspbian console, we write the following:
sudo nano /etc/hostapd/hostapd.conf
ssid=R2-NET -----------------> SSID Wifi Name
channel=6 -----------------> Channel
wpa_passphrase=0102030405 -> Wifi Password
We edit the necessary data and exit the editor with “CTRL + X” … saving the file. The next thing is to restart the server for the changes to take effect.
