SideQuest supports wireless ADB for installing apps over wifi - this is easy to setup but you must follow certain steps.
You must first connect your Quest via the USB2 cable to Sidequest before you can enable wireless mode - you will need to do this every time your headset reboots.
Connect to Sidequest and ensure you have a green dot and are ‘connected’ If not connected see here: Device Not Connected
Make sure your device and your computer are on the same wifi network.
The select the wifi icon along the top row and ‘Connect’
After you enable wireless mode SideQuest will show two connected devices - disconnect the USB cable to show only one.
You can reconnect to wifi if you restart SideQuest as long as you haven’t restarted your headset.
