# Yealink Wi-Fi setup

> Connect a Yealink desk phone to your wireless network, including which models need a WF40 or WF50 Wi-Fi adapter.

You can connect most Yealink desk phones to a wireless network instead of running an Ethernet cable. Some models have Wi-Fi built in, while others need a USB Wi-Fi adapter.

## Check adapter compatibility

Confirm which adapter your phone needs before you start:

| Model      | Wi-Fi support                                             |
| ---------- | --------------------------------------------------------- |
| T42S, T46S | WF40 adapter (2.4 GHz)                                    |
| T48S       | WF50 adapter (2.4 GHz or 5 GHz) or WF40 adapter (2.4 GHz) |
| T4xU       | WF50 adapter (2.4 GHz or 5 GHz) or WF40 adapter (2.4 GHz) |
| T5xW       | Built-in Wi-Fi — no adapter needed                        |

<Note>
  The T5xW series has Wi-Fi built in, so you can skip the adapter step below.
