 In the section above, you can see whether you are currently connected to Wi-Fi, see your current IP address and toggle the network indicator on or off.

+KNULLI has some additional options which are hidden from the GUI for the tech-savvy user to take advantage of. Through the GUI you may choose only a single Wi-Fi network SSID through discovery and provide a key through the soft keyboard. But if you're a gamer on the go, you may want a touch of flexibility for additional hot spots. You can configure a secondary and tertiary Wi-Fi by editing `batocera.conf` directly. You can access the file by the same why you add your games as described in the [Add Games](../../play/add-games) section, or use a command line editor via [SSH](../../ssh). The file is located at `/userdata/system/batocera.conf` or `SHARE\system\batocera.conf` depending on your perspective. In `batocera.conf`, simply find and edit the following lines:

+```
+## Secondary Wi-Fi
+wifi2.ssid=wifiname2
+wifi2.key=supergoodkey2
+
+## Third Wi-Fi
+wifi3.ssid=wifiname3
+wifi3.key=supergoodkey3

 !!! warning "Password protection"
 
     By default, your KNULLI device does not require a root password to access your device. Consequently, as soon as you connect to a network, the data on your device becomes accessible in your local network without any password protection. While this might be convenient within your own home, it might be a severe security risk when connecting to a network which is not under your control. We strongly suggest enabling **additional security**.
