By default, the M20d will use channel one of your created WiFi network... but you can change the channel it broadcasts on...
This is the most important step. A USB Wi-Fi device must be plugged into the
M20d’s USB port to enable the StageScape Remote app to connect with the
2. Customize the Unit Name (optional)
The Unit Name is the name the M20d broadcasts as a network name, also referred to as a
network SSID. By default, the M20d will set its Unit Name to “StageScapeM20d”.
You can edit the Unit Name by tapping the name field and entering new text. When entering text for
the SSID, some alphanumeric characters are disabled.
3. Select a Wiireless Channel (if Standalone is selected)
Select a Wi-Fi Channel from the Wireless Channel dropdown menu.
4. Select a Wi-Fi Network (if With an existing Wi-Fi Network is selected)
Select a local Wi-Fi Network if you’d like to join one. Tap the Network field and a window will open

Make a note of the four-digit Security PIN. The StageScape Remote app requires you to enter
these digits when connecting to your M20d. Note: The M20d automatically generates the four-digit
Security PIN specific to your device. The PIN cannot be customized.
Now you’re ready to configure Wi-Fi settings on your iPad®.

If the network broadcasts on channel 6, it'll be channel 6 etc.
In standalone, the M20d is the master in the network whereas in an existing network setup, the M20 is a slave
