Model :

Hardware Version : Not Clear

Firmware Version :

ISP :

We have a customer using the TD-W8970 with 4 Cisco SPA514G VoIP phones plugged directly in to the LAN ports.
All 4 ports repeatedly disconnect and reconnect, shown as "LAN Up" and "LAN Down" in the router logs. Only 1 packet is dropped if you are pinging the devices, but that's enough to stop audio for a few seconds.
Other devices such as a laptop work perfectly.

This is a known problem, and the solution provided by Cisco is to disable power saving, or "Green Ethernet" on the router. Is there a way to do this on the TD-W8970
If that's not possible, am I able to force the ports to 100mbps/full duplex instead of Gigabit?

Any suggestions appreciated.

TD-W8970 itself has no power saving feature.
Can you do it on your VoIP phones?

Cannot. We usually do it on computers.

Unfortunately, the phones don't allow us to force power saving or connection speed.
We have worked around the problem by installing a cheap unmanaged switch in between the phones and the router.
They seems to work fine now.
