OAK4 WiFi

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

Supported WiFi dongles

OAK4 ships with preinstalled drivers for dongles using these chipsets:
  • rlt881cu
  • mt7601u
We currently recommend using an mt7601-based dongle.

Connection setup

  1. Connect a supported WiFi dongle to the rear USB-C port on the camera. You will probably need to use a USB-A female to USB-C male adapter.
  2. Keep the camera connected with cable (Ethernet) for initial setup.
  3. SSH into the camera.
  4. 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.

Measured speed

Measured WiFi throughput is approximately 50 Mb/s.

Example usage
