I have the NBN connection box in my master bedroom with the tp-link Sagemcom 5G Home Broadband Modem that TPG sent me. Internet and wifi are working fine, just wifi signal is not very good on the ground floor, as the wifi router is on the first floor and at the extreme corner. I have the extra tp-link Archer VR1600v modem router from TPG before, and we were using NBN service too, but I believe it was a different type of connection and now it’s TPG NBN Fibre service.   So, how can I use the old modem router VR1600v as an extender/access point in order to enjoy the proper connectivity throughout the house seamlessly.   Please find the attached photos for 2 modems. Kindly help me out on this issue by providing the detailed steps on how to fix it. I tried checking other similar posts but didn’t get a proper solution, so, if you can provide the solution step-by-step, it will really be useful for me. Thank you in advance! ... View more
