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:
ModelWi-Fi support
T42S, T46SWF40 adapter (2.4 GHz)
T48SWF50 adapter (2.4 GHz or 5 GHz) or WF40 adapter (2.4 GHz)
T4xUWF50 adapter (2.4 GHz or 5 GHz) or WF40 adapter (2.4 GHz)
T5xWBuilt-in Wi-Fi — no adapter needed
The T5xW series has Wi-Fi built in, so you can skip the adapter step below.
