***We recommend using a wired network connection whenever possible. Running a phone on WiFi can increase latency, and a weak signal may result in poor call quality***

If you have a Yealink SIP-T54W, then it is possible to set it up with WiFi rather than a wired connection. We recommend using a wired network connection, but this can be used if there is no way to connect the phone physically.

To start, you will need to plug in the phone's power brick. Most of the time, your phone will be powered by the network connection, but this can't be done if you are connecting by WiFi.


When the phone boots, you want to go to the menu by pressing the menu button.

Select the basic Icon. You can navigate the menu with the arrow keys and press OK to select.

Scroll down and select the WiFi option.

If this is the first time using the phone's WiFi, then you will see the screen below. You want to make sure WiFi is selected, press switch, and then save. This will turn WiFi on for the phone.

After turning the WiFi on, you will want to connect the phone to your WiFi network. Go down and select available networks.

Select your WiFi network and press the connect button.

If your WiFi has no password, you can connect automatically. Otherwise, the phone will ask you for the password. To enter the password, use the buttons on your phone. Press the (ABC, ABC, 2ab, 123) button multiple times, and it will cycle through the numbers and letters on the button. Press the * key to input special characters ( ! * & ^ % $ # @ ?, etc.)

After you enter the password, press connect.

The phone will then start connecting to the WiFi network.

Once the phone is connected, you will see a green checkmark next to your WiFi SSID name.

On the home screen, you will see a green signal icon indicating you are connected.

You can now make and receive calls to and from your device.
