The Yealink Wi-Fi Dongle can be used in conjunction with the Yealink SIP T-27G, T-29G, T-41S, T42S, T-46G+S and T-48G+S.
Update your Yealink IP Phone with the latest firmware and plug the WF 40 Wi-Fi Dongle into the USB port on the back of your phone. The USB dongle will show up as connected in the interface of your phone and you will be able to connect your IP Phone via Wi-Fi to the Network. This is especially convenient when placing the phone where you have Wi-Fi coverage but can’t access to the LAN Network. For more information please refer to the WF40 User Guide or view the technical Data Sheet.
