@mkchong27 . Signal strength is determined by the router, not the connection type. - true. but if the connection type is unstabe, would it not affect the signal received by the modem / router? It is highly likely that the modem / router is giving the problem?    Does the VX220 have a System Log? Look for messages with PPP to see if the WAN link is dropping. - I looked at the log but don't know how to interpret it. Don't see "PPP" but "DHCPD" under "Type". The log has many pages   Is it possible to move the router to a more convenient place? Use a CAT6 ethernet cable from NBN box to router.   - I have tried moving out from the room where the NBN box is located to the other area where the devices are, but it did not help.   Do your wifi devices detect other wifi networks with strong signals? There could be some interference. - There are other wifi networks in the area but not that many. Even when there are ony 1 or 2 wifi networks detected, it does lags / buffering if not drops out (it's difficult to predict, sometimes it doesn't drop out/lag for hours!, though live connections via tvbox is deintiely lagging)   0 Likes   ReplyAccept as Solution   ...

When you had FTTN, where was the VX220 in your house? - In the dining area with the family hall but with TP-link Archer not VX220 Now on FTTP, where is the NBN box and VX220? Is it further away from where you use your wifi devices? - Both in the same area but now located in the guest hall separated from the dining & family area Has the wifi signal strength decreased from when you had FTTN? - With FTTN on a NBN50 Mbps, the signal is not strong. That's the reason for upgrading to FTTP NBN 100. With FTTN NBN100, the signal is strong but it appears unstable. Do you have ethernet computer? Any internet dropouts on it? - the duration is too short to know for certain as it's not practical to have it monitored for a long period of time, unlike mobile & tv box ... View more
