How to Enable Wi-Fi on Poly VVX Phones with 8x8 Express


Enable Wi-Fi support for supported Poly VVX Phones using Poly Wi-Fi network Adapter (previously known as OBiWi-Fi5G or Obihai Technology Wireless Adapter).

Applies To

  • Poly VVX phones running UC 5.8 Firmware with OBiWi-Fi5G USB dongle. Models include:
    • VVX 250
    • VVX 350
    • VVX 450
    • VVX 401
    • VVX 501

Enable Wireless Network Connectivity

You can enable wireless connectivity for your USB-enabled VVX phone using the Poly Wi-Fi wireless network adapter.

VVX phones use 2.4GHz or 5GHz default radio bands.



  • Device firmware needs to be updated to version 5.9.4.
  • Before setting up a wireless network, make sure that you connect the VVX phone to its power adapter.
  1. Insert the Poly Wi-Fi wireless network adapter into the USB port of your VVX phone.
  2. Go to Settings Basic Wi-Fi.
  3. Select Wi-Fi, then select On.
  4. Select Yes to reboot the phone.

After the phone reboots, Wi-Fi is enabled.

The phone scans for wireless networks and lists any that are available. If the phone does not automatically scan, select Scan to manually initiate a Wi-Fi network scan.

Connect to a Secured Wireless Network

Poly UC software supports different wireless network security profiles like Personal and Enterprise modes for better security. You can select a PSK or an enterprise-based security option to connect your VVX phone to a secured wireless network.
