Connecting Phones via the Dongle
Before setting up wireless, it is important to note that the IP phone ONLY has the power adapter connected; NO Ethernet cable (either wired Ethernet or Ethernet over Power) should be connected as this will automatically disable the Wi-Fi functionality on the Yealink T4x phone and the user will not be able to configure their wireless network information on the device.
You will also need to know both your SSID (Wi-Fi Network Name) & Wireless Password/Key.
Important: when connecting the phone to the Internet for the first time kindly connect the device via Ethernet cable so it could provision correctly. Due to the number of reboots that occur during provisioning, it has been found to be more beneficial to provision the phone using an ethernet connection rather than wireless. The device can be moved to wireless after it has completed, this is just temporary to complete the initial provisioning without an error occurring.
Note: the Wi-Fi password encryption on the Wi-Fi router must be either set to WPA-PSK or WPA2-PSK, in order for the Wi-Fi dongle to connect to the secured network.
To Install and connect to a Wireless Network:
- Insert the Wi-Fi USB Dongle 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 OKbutton. 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 Dongle
- 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
- 126.96.36.199 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 the router is handling DHCP on WiFi properly. On some routers DHCP on WiFi will not give out IP addresses to the devices with the same names. This has been a known issue on Verizon Fios Quantum Gateway Wi-Fi Router FIOS-G1100.
- 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, distortion 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.
