WiFi hotspot

I have acquired an Erle-Brain with WiFi dongle, which is the netword ID and password? How can I change it?

The name of the WiFi network is erle- and the password holaerle. If you wish to change default name, open

 /etc/hostapd/hostapd.conf

and change the line ssid=erle-<product> Instead of erle-<product>, write down desired name. And do the same with wpa_passphrase=holaerle to change the password.
