Wi-Fi USB Dongle WF40 to seamlessly connecting their IP phones to available wireless networks.
Requirements for using the WF40:
The following hardware is required to utilize this Wi-Fi solution:
- An existing Wi-Fi enabled network
- The Wi-Fi transmitter will need to support the 2.4 GHz frequency
- The Wi-Fi transmitter must support either WPA-PSK or WPA2-PSK encryption
- Yealink Wi-Fi USB dongle(s), model WF40
- Yealink brand desk phone(s) with USB Wi-Fi dongle support
- The WF540 is compatible with: Yealink SIP-T27G/T29G/T46G/T48G/T41S/T42S/T46S/T48S/T52S/T54S
- For T48G: upgrade to the version of 184.108.40.206 or higher
- For T29G/T46G/T46S/T48S: upgrade to the version 81 or higher
- For T27G/T41S/T42S: upgrade to the version of x.81.0.110 or higher
To Install and connect to a Wireless Network:
- Insert the Wi-Fi USB Dongle WF40 into the USB port on the back of the phone when the phone is in the idle state. The touch screen will prompt: Wi-Fi adapter connected. Scan for available Wi-Fi networks?
- Tap the OK button. The IP phone will toggle the Wi-Fi to on and search for available wireless networks in your area.
- When the scan is completed, you will see a Scan soft key on the screen; this can be pressed to re-scan available Wi-Fi networks.
- Use the arrow keys to navigate to the desired wireless network (SSID) on the screen, to connect to it, and press the OK button.
- If the network is secure, you will receive a Wi-Fi Password field to enter the password/key; enter the password here.
- Once the connection has completed successfully, the prompt Connected Successfully appears at the end of the desired SSID.
Disabling Wi-Fi Feature on the IP Phone:
To disable Wi-Fi feature, do one of the following
- Tap ->Basic->Wi-Fi. Mark the Off radio box in the Wi-Fi field.
Troubleshooting steps for the WF40
- Connectivity Issues – Phone doesn’t recognize dongle, Wi-Fi network not displayed, Wi-Fi fails to connect.
- Verify using on T46G or S or T48G or S
- If using Anyphone BYOP, verify Yealink phone firmware is:
- x.81.0.110 or higher for T46G
- 220.127.116.11 or higher for T48G.
- Verify SSID broadcast is on in the router, DHCP is on, and there are enough IP addresses in the DHCP range.
- Verify wireless network is 2.4GHz with WPA-PSK or WPA2-PSK and using 802.11b/g/n.
- Confirm distance between dongle and Wi-Fi transmitter is less than 150ft and not a lot of walls, x-ray machines, microwaves, large electronic devices in between them.
- QoS Issues - Choppy Audio, audio loss, distrotion or noise.
- Confirm distance between dongle and Wi-Fi transmitter is less than 150ft and not a lot of walls/x-ray machines/large electronic devices in between them.
- Run a wi-fi analyzer/scanner on a smartphone or a laptop to find the channel with the least interference from other nearby access points, then change your access point's Wi-Fi channel to that.
- Routers with certain firmware sometimes have a built-in Wi-Fi scanner or analyzer, such as Asuswrt-Merlin firmware, though they often can only operate either as access point or as a scanner.
