Model: TD-W8970
Hardware Version: V1
Firmware Version: latest

I have a W8970 which I wish to use as an access point to extend my home network because it has external antenna connections and I need to use a wall-mounted external antenna already installed at the rear of the house to get a signal above a summerhouse in the garden.

 

The primary router is at the front of the use and not in range of the W8970 but I have successfully extended that using a powerline pair of a PA4010 and WPA4220.

 

The WPA4220 and W8970 will be adjacent so I could use a direct wired connection from the WPA4220 into the W8970 WAN port but I have seen a previous post that says that this is not supported by the W8970.

 

Can someone please point me at some instructions for setting that up if it is possible, I have tried W8970 to dynamic IP fails to get a lease and setting a fixed address produces a message saying the WAN and LAN can't have the same subnet.

 

Failing that, if the W8970 doesn't support the wired approach, are there instructions for setting up WDS using the WPA4220 as the source. I have found something along those lines here but they refer to a more modern family of devices and the functions listed don't appear in the W8970 setup pages:

You have two choices to configure TD-W8970 in your network avoiding double NAT:

1. WDS.

2. AP mode (Case 2). Keep the TD-W8970 in ADSL Modem Router Mode when you configure it.

 

I would suggest to use the second option - it's more stable and faster due to the ethernet connection used.

These are the three modes in TD-W89700:

I recommended the first because all LAN 1-4 can be used for uplink/downlink.

In Wireless Router Mode only LAN 1-3 can be used, because LAN 4 is WAN port actually and this will not work configuring the TD-W8970 in AP mode.

Thank you @terziyski, that was just what I needed. In fact I had previously guessed everything correctly apart from one detail that I got from the video, the cable link from the powerline extender had to be plugged into one of the "LAN" sockets, not the "WAN/LAN" socket.

 

Other than that, the trick was to give the W9870 a fixed IP address (I reduced the DHCP range in the primary router by a few to avoid any possible conflict) and disable the local DHCP server.

 

What is the significance of configuring it as an ADSL router rather than in "Wireless Access Point" mode?

Ah, thank you @terziyski. That explains why connecting the powerline extender to the WAN port in Wireless Router Mode didn't work. I had assumed the WPA4220 was playing the role of the WAN.

 

Best regards
