Thanks @david64.   The signal strength on the 2nd floor is a bit weak in certain areas.   When I searched for an extender today, I saw TP-Link AX1800 deco x20.  Information on the box is limited. Would you know if this deco device works with any of my router?  If so, could I connect it to C1200 via Ethernet cable as per your suggested method in your previous post?   Thanks, Nelson ...

Hi @david64,   Thank you for your advice.  Much appreciated.    My house has a second floor and there is need for internet access in the basement. I am not using TPG VOIP phone service, just the normal phone service as part of the NBN bundle.  Each room only has 1 outlet going to the communication box in the basement.  I have connected the devices as per your advice and now have a wifi network with 2 SSID. I am currently using two C1200 LAN ports - port#1 for connecting to VR1600 and port#2 for connecting to a smart TV.  I would like to check if I have connected the devices properly.  Below please find a few additional queries: (1) is it normal to have 2 SSIDs instead of 1 SSID under your suggested setting? (2) you suggested connecting a cable from Ethernet outlet to LAN port of VR1600 - please confirm not to connect the cable to the blue WAN port; (3) I notice the VR1600 home page (192.168.1.2) shows a red cross next to the internet icon - please confirm if this is ok; (4) is it correct that I still need to input TPG account username and password in the internet setup section of the VR1600?   Once again, thank you very much for your help.   Kind regards, Nelson ...
