| Requirement | Details |
|---|---|
| Network access | The W80B and W80DM must be on the same IP subnet and able to reach each other. Multicast (UDP 5060 / RTP range) should not be blocked between them. |
| W80DM web UI credentials | Default: admin / admin (change this if you haven't). Access via browser at the DM's IP address. |
| W80B MAC address | Printed on the label on the bottom or back of the base station. Format: 80:5E:C0:XX:XX:XX |
| Physical access to W80B | Required if a hardware reset is needed (Step 3). |
| Firmware compatibility | W80B and W80DM firmware should be on the same major release branch. Mismatched firmware is a common cause of sync failure. |
The W80DM acts as the DECT network controller. It manages handset registrations, call routing, and handover between base stations. The W80B base stations are "dumb" RF endpoints — they must be registered to the DM before they become active.
When a W80B is factory-fresh or has been reset, it enters discovery mode and broadcasts on the local network looking for a DECT Manager. The W80DM can discover it automatically (if Auto-Discovery is on) or you can add it manually by MAC address.
A base station shows as Disconnected or disappears from the DM's list when:
Open a browser and navigate to http://<W80DM-IP-Address>. Log in with your admin credentials.
Go to Status → Base Station Status. You will see a list of all known base stations and their current state.
Look for a base station showing any of these states:
Note the MAC address of the base station you need to resync.
In the W80DM web UI, navigate to DECT → Base Station.
Locate the base station entry by MAC address. Click Delete (or select the checkbox and use Delete Selected). Confirm when prompted.
admin).There are two methods: Auto-Discovery (easiest) and Manual Add (more reliable in complex networks).
In the W80DM web UI, go to DECT → Base Station. Click Auto Discover or ensure the Auto Discover Base Station toggle is enabled.
Within 1–2 minutes, the W80B should appear in the discovered list with a status of Authenticating or Connecting. If it does not appear, verify Layer 2 connectivity between the devices (same VLAN, no multicast filtering).
If the DM requires manual authorization of discovered base stations, click Accept next to the newly discovered W80B. The DM will push its configuration and the base station will register.
In the W80DM web UI, go to DECT → Base Station.
Click Add. Enter the following details:
BS-01-Floor2).Click Confirm to save.
The W80DM will attempt to locate the W80B on the network using its MAC address. Once found, it will push configuration automatically. This process typically completes in under 2 minutes.
Navigate to Status → Base Station Status. The W80B should now show as Connected with an active IP address and firmware version populated.
The front LED on the W80B should be solid green (or pulsing slowly, depending on firmware). A rapidly flashing LED indicates it is still searching for the DM.
Register or re-register a W80 DECT handset via DECT → Handset in the DM UI. Place a test call to confirm audio path through the newly synced base station.
| Symptom | Likely Cause | Resolution |
|---|---|---|
| Base station not appearing in Auto-Discovery | Devices are on different VLANs, or multicast is blocked | Ensure W80B and W80DM are on the same L2 segment. Check switch/VLAN config. Use Manual Add as a workaround. |
| Status shows "Disconnected" after re-adding | IP conflict, firewall rule, or wrong DM address on the base station | Verify the W80B's IP is reachable from the DM. Check ping <W80B-IP> from the DM host. Check for duplicate MAC/IP entries. |
| Base station registers but then drops off | Firmware mismatch between W80B and W80DM | Update firmware on both units to the same release. Yealink recommends keeping DM and BS on matching firmware branches. |
| "Authentication Failed" in DM log | The base station may still have an old DM association from a prior config | Perform a full factory reset on the W80B (hold reset pin 15+ seconds for a deep reset). Re-add via DM. |
| LED stays amber after reset | Base station in discovery mode but no DM found | Confirm DM is powered on and reachable. Verify DHCP is assigning the W80B an IP on the correct subnet. |
| Cannot access W80DM web UI | DM IP changed after a DHCP renewal | Check DHCP leases for the DM's MAC. Consider assigning a static IP or DHCP reservation for the W80DM. |
