Installing Obihai Technology OBiWiFi5G USB WI-Fi Adapter (Poly)

The ObiWiFi5G USB Wi-Fi Adapter allows Poly phones to connect to the Internet wirelessly. There are times when a physical phone is needed, and there may not be a wired internet connection available. A Wi-Fi adapter provides the freedom to place a phone, such as Poly VVX, anywhere within range of Wi-Fi.

NOTE: Nextiva recommends using a Wi-Fi adapter only when required. Due to the nature of VoIP service, customers can experience audio quality issues when using phones on an unstable connection.

NOTE: To troubleshoot audio quality issues, Nextiva Support requires a hardwire connection.
