Wi‑Fi Support for Polycom VVX Series USB Capable Phones
Overview & Recommendation
WebVault strongly recommends using physical Ethernet cabling to ensure optimal call quality and reliability. However, for situations where Ethernet isn't feasible, Wi‑Fi via USB dongles can be used as a temporary solution to enable internet connectivity on Polycom phones with a USB port.

WIFI Setup Instructions
Verify firmware version on your VVX via Settings > Status > Version.
Insert the dongle (Edimax or OBiWiFi5G) into a USB port on the back of the phone.
When prompted, select Start and then enable Wi‑Fi; the phone will reboot.
After reboot, navigate to Settings > Basic > Wi‑Fi:
The phone scans and lists available Wi‑Fi networks.
Choose your SSID and enter credentials.
Confirm the connection. A Wi‑Fi icon appears on the home screen.
Note: Ethernet must be disabled manually if both connections are active.
Limitations & Best Practices
Temporary use only: Wireless is suitable only in strong, stable networks.
No dual connectivity: Ethernet is disabled when Wi‑Fi is active.
Audio/video constraints: No video support; USB headsets disabled when Wi‑Fi dongle is in use.
Signal strength matters: Ensure excellent signal to avoid call issues.
Enterprise support: Enterprise security (802.1x) is supported.
Troubleshooting Tips
Ensure firmware is current.
If the dongle is not detected, reboot the phone and reinsert it.
To reset credentials, go to Settings > Wi‑Fi > Forget, then reconnect.
For debugging, WLAN logs can be enabled in the phone's web interface.
Revert to wired Ethernet if call quality suffers over Wi‑Fi.
