Yealink WF40 is a plug-and-play solution to add WiFi connectivity to a compatible Yealink IP phone. Simply put the dongle into the USB slot, and the phone will automatically scan for wireless networks. You can then choose the appropriate network, enter the password, and that's it: your phone is connected. With a maximum transmission rate of 150 Mbps, the WF40 gives you enough bandwidth for high-quality and stable audio.
Note: if your phone is connected to the LAN via an Ethernet cable, the wired connection takes precedence over the wireless connection. Unplug the Ethernet cable that runs to the LAN to activate the WF40.
