Wi-Fi Network Connection and Management

Jump to:



The Wi-Fi function of the Yealink T48S allows you to enjoy SIP connectivity without a network cable. This reduces clutter, lets you easily move the phone around your office, or serves as a solution for offices with a Wi-Fi only network.


Note that the phone is POE compatible. Meaning it can receive power from the Ethernet cable that provides the network connectivity. If you are not using an Ethernet cable you will need to use the power supply that came with your phone.


To use Wi-Fi on your T46S phone you need to purchase the Yealink WF40 or WF50  Wi-Fi USB dongle and plug it in the USB port on the back of the phone.



All the following Wi-Fi options can also be configured via the web user interface by selecting the Network tab on the top and the Wi-Fi options from the side panel.


Activating/Deactivating Wi-Fi and Scanning for Networks


When the WF40 Wi-Fi dongle is plugged in the USB port, the phone prompts you to scan for wireless networks. Select OK to activate Wi-Fi mode directly and scan for Wi-Fi devices automatically.


If you cancel the automatic scanning or turned off Wi-Fi you can activate it manually:


  • Tap >Basic>Wi-Fi.

  • Select On from the Wi-Fi field.

  • Select Save.

The phone scans the available wireless networks in your area. 


If you want to deactivate Wi-Fi follow the same steps but simply select Off from the Wi-Fi field.


Connecting to a Wireless Network


There are three ways to connect the phone to the wireless network: manual connection, Wi-Fi Protected Setup (WPS), and manually adding a wireless network.


Manual Connection (and Disconnection)


To manually connect to a wireless network:


  • Tap >Basic>Wi-Fi.

  • Tap X Available Network(s) (X represents the number of available networks).

  • If there is no available wireless network, Tap Scan.

  • Tap the desired wireless network you want to connect to and tap >Connect.
  •  If the network is secure, enter its password in the Password field when prompted.

    For information about the password of the wireless network, please contact your system admin.
  • If the connection is successful appears after the name of the wireless network. Also the Wi-Fi icon () appears on the status bar.

If you want to disconnect any network simply follow the same steps to select it and press the Disconnect soft key. 


Wi-Fi Protected Setup (WPS)


Wi-Fi Protected Setup (WPS) provides a simplified mechanisms to configure a secure wireless networks. 


Two methods are supported for Wi-Fi protected setup:


  1. Push Button Configuration (PBC): The user simply has to press a WPS key on both the IP phone and the wireless router to connect.

  2. Personal Identification Number (PIN): The user has to enter a PIN generated randomly by the phone on the wireless router to connect.

To connect to the wireless network using PBC method:


  • Tap >Basic>Wi-Fi.

  • Tap WPS.

  • The screen prompts “WPS has been activated, connect in 120s!”.

  • Long press the WPS key on your wireless router.

  • If the connection is successful    appears after the name of wireless network.

To connect to the wireless network using PIN method:


  • Tap >Basic>Wi-Fi.

  • Tap WPS-PIN.

    The screen prompts “Please input below PIN code on your Wi-Fi router and press OK to connect: xxx” (xxx represents the PIN code you have to enter.)

  • Log into your wireless router’s web interface, configure it to search WPS clients, and enter the PIN code generated by the phone in the relevant field.

    You will generally find these option under a Wireless or WPS tab or section of the web interface, but this may vary by brand or model. For more information please refer to the documentation of your wireless router.

  • Select OK on the phone to start the connection process. This may take 2-3 minutes.

    The web interface will prompt you with a success message once the connection is established. 

Manually Adding a Wireless Network


If the SSID broadcast option of your wireless router is disabled, the Wi-Fi network of the router might not appear in phone's scanning results.


In that case, you need to either enable the SSID broadcast or manually add a wireless network.


To manually add a wireless network:


  • Tap >Basic>Wi-Fi.

  • Tap Known Network(s) and tap Add.

  • Use the WLAN settings obtained from your wireless router to configure the WLAN Profile on the phone:

    • If your wireless router security mode is set to None or WEP enter the profile name, SSID and WPA shared key in the corresponding fields.

    • If your wireless router security mode is set to WPA-PSK or WPA2-PSK select the desired Cipher type (TKIP, AES or TKIP AES) from the Cipher Type pull-down list and enter the profile name, SSID and WPA shared key in the corresponding fields.

  • Select the Save.

  • The connected wireless networks will be saved to the Known Network(s) list that can store up to 5 wireless networks, each with its own connection priority that you can edit (see Managing Networks below.)

Viewing Wireless Network Information


To view wireless network information do one of the following:


  • Tap >Basic>Wi-Fi.

    Select X Available Network(s) (X represents the number of available networks) and tap Detail to view the wireless network information (e.g., Profile Name, SSID or Signal Strength).

  • If the phone is already connected to a wireless network successfully, you can also Tap >Basic>Wi-Fi>Wi-Fi Status.

Managing Networks


Once the phone has been connected to a wireless network successfully, the wireless network profile will be saved in the Known Network(s) list. The next time you enable the Wi-Fi feature, the phone will automatically connect to the wireless network which has the highest priority (the top one). 


Up to 5 wireless network profiles can be saved in Known Network(s) list. If you want to add a new one when the list is full you need to delete the oldest profile first.


To manage known network(s):


  • Tap >Basic>Wi-Fi>Known Network(s).

  • Tap and do one of the following:

    • Tap Edit to edit the wireless network profile, edit the desired wireless network information, and press the Save soft key.

    • Tap Move Up or Move Down to improve or lower the priority of the wireless network that the phone automatically connects to.

    • Tap Delete or Delete All to delete the saved wireless network profile(s).

  • If you delete a wireless network profile you need to manually connect to it the next time you want to use it.
