Welcome to TPG Community!
Unfortunately, WDS is not supported on VR1600v.
Why disable a basic feature when this functionality is clearly available in the base model of this modem as per the 3rd post in this thread where the manual from the mfr is provided with instructions how to access WDS??
I literally just got my FTTB hooked up today by your techs - and it's all good - but the building I'm in has very heavy thick concrete walls which creates quite DEAD dead zones - and there's no facility to cable a new phone point further down the hallway - so my bedroom is a very weak signal.
I have an older netgear that I can configure as a wifi repeater - but from everything I'm reading I need to be able to enable WDS in the TP-Link first.
Due to security issues within the WDS function, we decided to disabled it.
You have options to improve your home WiFi network.
You may purchase a Mesh network to improve wireless connection at your home, however we do not recommend any specific brand or model.
In case you have one, you will need to contact the manufacturer to get support on how to set up the device.
Let us know should you require further assistance.
