IP Address Issues
The device does not get an IP address
Do one of the following:
If your device connects to the wired network:
l Ensure that the Ethernet cable is plugged into the Internet port on the IP phone and the Ethernet cable is not
loose.
l Ensure that the Ethernet cable is not damaged.
l Ensure that the IP address and related network parameters are set correctly.
l Ensure that your network switch or hub is operational.
l Ensure that the Wi-Fi feature is disabled.
If your phone connects to the wireless network:
l If the network is secure, ensure the entered password is correct.
l Ensure your gateway/router enables the wireless network feature.
Solving the IP conflict problem
Do one of the following:
l Reset another available IP address for the IP phone.
l
Check network configuration via the phone user interface at the path Menu > Advanced (default password:
admin) > Network > WAN Port > IPv4 (or IPv6). For black-and-white phones, navigate to Menu > Settings >
Advanced Settings (default password: admin) > Network > WAN Port > IPv4 (or IPv6). If the Static IP is selec-
ted, select DHCP instead.
The Specific format in configuring IPv6 on Yealink phones
Scenario 1:
If the IP phone obtains the IPv6 address, the format of the URL to access the web user interface is “[IPv6 address]”
or “http(s)://[IPv6 address]”. For example, if the IPv6 address of your phone is “fe80::204:13ff:fe30:10e”, you can
enter the URL (for example, “[fe80::204:13ff:fe30:10e]” or “http(s)://[fe80::204:13ff:fe30:10e])” in the address bar of a
web browser on your PC to access the web user interface.
