City Cloud Phone – How to Use WiFi on Yealink T43U with WF50 Dongle

The Yealink T43U is a modern SIP phone included in all City Cloud Phone packages. It supports Wi-Fi connectivity, allowing you to connect without an Ethernet cable. This is ideal for offices with limited network ports, Wi-Fi-only setups, or simply to maintain a tidy, cable-free workspace.

To enable Wi-Fi on the T43U, you’ll need a Yealink Wi-Fi USB dongle (WF50). Just plug the dongle into one of the two USB ports on the back of the phone.

If you’re also using an expansion module, it’s recommended to plug the Wi-Fi dongle into the upper USB port.

Please note:

The Yealink T43U supports Power over Ethernet (PoE). If you’re not connecting via network cable, you’ll need to power the phone using the included power supply.

Using Wi-Fi Protected Setup (WPS)

WPS offers a quick method of connecting, but it is considered less secure and should only be used when necessary. Disable it on your router when not in use.

There are two WPS options:

Push Button Configuration (PBC)

Go to Menu > Settings > Basic Settings > Wi-Fi
Press the WPS soft key and choose WPS
You will see “WPS has been activated, connect in 120s”
Press the WPS button on your router
If successful, a Wi-Fi icon will appear next to the network name

PIN Method

Go to Menu > Settings > Basic Settings > Wi-Fi
Press the WPS soft key and select WPS-PIN
A PIN will be displayed on the screen
Log into your router’s admin page and enter the PIN in the WPSsection
Press OK on the phone to begin the connection

Connection may take a few minutes. Your router should confirm when it is successful.

Adding a Hidden Network Manually

If your router does not broadcast its SSID, the network will not appear in the available list. You can still connect by adding it manually:

Go to Menu > Settings > Basic Settings > Wi-Fi
Highlight Known Network(s) and press Add
Enter the network details:
- Profile Name (a name you assign)
- SSID (the network name)
- Security Mode (e.g. WPA2-PSK, WEP or None)
- Password if required
Press Save

The network will be saved in the Known Network(s) list.

Understanding Available and Known Networks

Once Wi-Fi is switched on, you will see two options:

Available Network(s) are networks currently in range.
Known Network(s) are networks the phone has connected to previously. The phone can store up to five known networks.

The T43U will reconnect to the highest priority known network automatically when Wi-Fi is turned on again.

Viewing Network Information

To view Wi-Fi details:

Go to Menu > Settings > Basic Settings > Wi-Fi
Highlight Available Network(s), select a network and press Detail
If connected, you can also go to Wi-Fi Status to see information about the active connection

Managing Known Networks

The phone stores up to five known networks and prioritises them automatically.

To manage these:

Go to Menu > Settings > Basic Settings > Wi-Fi > Known Network(s)
Press Option to:
- Edit a network profile
- Move Up/Down to change connection priority
- Delete or Delete All to remove saved profiles

If you delete a network, you will need to reconnect manually next time.
