## Procedure

### 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.

**Prerequisite:**

- 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.

> [!NOTE]
> ***Note****:*
> 
> *The administrator can configure the regulatory domain for your location and radio frequency bands on which the wireless network operates. If not configured, the phone uses the Global regulatory domain and 2.4 GHz and 5 GHz default radio bands.*

### 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.

1. Go to **Settings** > **Basic** > **Wi-Fi**.
2. Do one of the following:
  - **For a WPA(2)-PSK network**: enter the Password.
  - **For a WPA2-enterprise network**: enter User ID and Password.
3. Select **Connect**.

The phone connects to the Wi-Fi network and displays the Wi-Fi connection status on the Menu and Home screens. Supported Enterprise Security Modes:

- EAP-PEAP/MSCHApv2,
- EAP-FAST
- EAP-TLS

> [!NOTE]
> Note:
> 
> *Your administrator sets the appropriate EAP method to connect to an enterprise-based network.*

### Disconnect from a Wireless Network

1. Go to **Settings** > **Basic** > **Wi-Fi**.
2. Select the **connected wireless network SSID** from the list.
3. Select **Disconnect**.

## Limitations

- Firmware 5.8.0.13337 will show the Wi-Fi option under **Settings** > **Basic** > **Wi-Fi** even if no dongle is installed.
- Enabling Wi-Fi automatically disables the LAN (Ethernet) port.
- You cannot use Wireless and Wired connections simultaneously to connect your VVX phones to the network.
- WEP is not supported.
- No Video calls or IPv6.
- New VVX 250, VVX 350 or VVX 450 cannot use USB Headset concurrently at present.
- Some Poly VVX phones will have Bluetooth capability but always require the USB dongle to actually connect to Wi-Fi networks.
