let me start with the background of my problem, I am having a FTTN NBN and dont get speeds more than 25Mbps, also I believe my house is far from the node Which makes things worse. I had Kogan internet ( vodafone) without much complaints, however I now switched to Aussie BB based on various reviews and their local customer service. ABB is giving almost same speeds and bit less at times but I have noticed a lag in my online game play and live streaming.
I was advised to get the wiring checked and use an wifi extender by few and powerline adaptor by others. I need help from the forum whether any of these would really be useful.

Also thinking to switch back to Kogan.
You’re better off investing in a mesh network like Netgear Orbis, Amazon Eeros, etc.
