Hey there, managing 25+ Android devices over WiFi without that initial USB setup is totally doable—here are the most reliable approaches I’ve used for similar enterprise-scale scenarios:

This is Google’s official, USB-free method, perfect for modern devices:

• First, enable Developer Options on each device:
  • Open Settings → About Phone, tap Build Number 7 times until you see "You are now a developer!"
• Head into Developer Options and toggle on Wireless Debugging
• The device will show a pairing code, IP address, and two ports (one for pairing, one for ADB)
• On your computer, open a terminal/command prompt and run the pairing command:

  adb pair <device-ip>:<pairing-port>
  

  Enter the on-screen code to complete pairing
• Once paired, connect to the device’s ADB port:

  adb connect <device-ip>:<adb-port>
  

• Verify the connection with adb devices—you should see the device listed
• Pro tip for bulk operations: Write a simple bash/Python script to loop through a pre-collected list of device IPs, pairing codes, and ports. Have your device admins pre-configure and export these details to save time.

If these are managed enterprise devices, MDM tools eliminate manual setup entirely:

• Pick an MDM platform that supports ADB remote debugging (like Google Workspace for Android, Microsoft Intune)
• In the MDM console, create a configuration profile that enables ADB Network Debugging and sets a fixed ADB port
• Push this profile to all devices—they’ll automatically enable wireless ADB with your specified settings
• After deployment, you can connect to any device directly with adb connect <device-ip>:<fixed-port> no pairing or USB needed
• Why this shines: It’s scalable, secure, and lets you centrally manage debugging permissions across all devices.

If you’re working with rooted or test devices, you can pre-enable wireless ADB in the firmware:

• Flash a custom ROM or Recovery that enables wireless ADB by default on boot
• Once the device starts, it’ll automatically run the ADB wireless service—you just need its IP to connect
• Caveat: This carries a risk of bricking devices and violates most enterprise security policies, so only use this for isolated test environments.

• All devices and your computer must be on the same local network—cross-segment connections will fail
• For Android 11+, pairing codes are one-time use; once paired, you won’t need to re-pair unless the device is reset
• Assign static IPs to all devices to avoid connection issues from dynamic IP changes
• Never enable wireless debugging on public networks—it exposes devices to unauthorized access
