Ensure that the Wi-Fi feature is disabled.
If your phone connects to the wireless network:
If the network is secure, ensure the entered password is correct.
Ensure your gateway/router enables the wireless network feature.
Solving the IP conflict problem
Do one of the following:
Reset another available IP address for the IP phone.
Check network configuration via phone user interface at the path Menu->Advanced (default
password: admin) ->Network->WAN Port->IPv4 (or IPv6). If the Static IP is selected, select DHCP
instead.
Specific format in configuring IPv6 on Yealink IP 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.
Scenario 2:
Yealink IP phones support using FTP, TFTP, HTTP and HTTPS protocols to download configuration files or
resource files. You can use one of these protocols for provisioning.
When provisioning your IP phone obtaining an IPv6 address, the provisioning server should support IPv6
and the format of the access URL of the provisioning server can be “
tftp://[IPv6 address or domain
name]
”. For example, if the provisioning server address is “2001:250:1801::1”, the access URL of the
provisioning server can be “tftp://[2001:250:1801::1]/”. For more information on provisioning, refer to
Yealink_SIP_IP_Phones_Auto_Provisioning_Guide.
Time and Date Issues
Display time and date incorrectly
Check if the IP phone is configured to obtain the time and date from the NTP server automatically. If your
phone is unable to access the NTP server, configure the time and date manually.
