OAK4 WiFi

OAK4 does not have built-in WiFi. To connect it wirelessly, plug in our M8 WiFi Adapter or a supported USB WiFi dongle into the rear USB-C port.

Supported WiFi devices

OAK4 supports the following WiFi devices:
  • M8 WiFi Adapter
  • Any USB WiFi dongle using the rlt881cu or mt7601u chipset.
We currently recommend using our M8 WiFi Adapter.

Connection setup

  1. Make sure your camera is running RVC4 v1.30.1 or later.
  2. Connect a supported WiFi Adapter
    • For M8 WiFi Adapter, connect it to the rear M8 auxiliary port on the camera with the included M8 cable.
    • For USB WiFi dongle, connect it to the rear USB-C port on the camera. You might need a USB-A female to USB-C male adapter.
  3. Keep the camera connected with cable (Ethernet) for initial setup.
  4. SSH into the camera.
  5. Run nmcli to join your WiFi network.
Command Line
1# From your host computer
2ssh root@<camera-ip>
3
4# On the camera
5nmcli d wifi connect <ssid> password <password>

Troubleshooting:

If you see:
Text
1Error: Failed to add/activate new connection: failure adding connection:
2error writing to file '/etc/NetworkManager/system-connections/...':
3Read-only file system
/etc is mounted read-only. Remount it as read-write and restart NetworkManager, then retry the nmcli command:
Command Line
1mount -o remount,rw /etc
2systemctl restart NetworkManager
This can happen after setup flows that switch parts of the filesystem to read-only mode.

Example usage
