Yealink phone says "No Internet," try these troubleshooting steps:
Check Network Cables:
Ensure the Ethernet cable is securely connected to both the phone and the network switch or router.
Verify Power Supply:
If you're using Power over Ethernet (PoE), ensure the switch or injector is working. Otherwise, check if the power adapter is properly connected.
Restart the Device:
Unplug the power cord (or Ethernet cord if using PoE) from the phone, wait for 10 seconds, and plug it back in.
Check Internet Connection:
Make sure your internet connection is active and that other devices on the network can access it.
Network Configuration:
Access the phone's menu by pressing the "OK" button.
Navigate to "Status" and check the IP address. If it shows 0.0.0.0, the phone isn't receiving an IP address.
Also, check that the phone is set to DHCP. Go to “Menu” > “Advanced” > “Network” > “WAN Port” > “IPv4” and select “DHCP.”
Firewall and Port Settings:
Ensure that the necessary ports for SIP/RTP traffic are open on your firewall.
Firmware Update:
Check if your phone's firmware is up to date. You can usually find updates on the Yealink support website.
Reset the Phone:
As a last resort, perform a factory reset. Go to “Menu” > “Settings” > “Advanced” and enter the admin password to access the reset option.
If none of these steps resolve the issue, it might be a good idea to contact your IT department or service provider for further assistance.
