Would getting a new router improve a powerline connection at all?Well I did say it depends on your own household wiring, so its not like I'm saying it will definitely work for everyone. It's a suggestion I gave because it's something that has worked well for me. I don' t have any other option available to me due to the distance of the router and number of concrete walls inbetween. The connection would be too weak, even for the purpose of browsing the net reliably. I'm able to get 2.4ghz and 5Ghz wifi and ethernet access in my office/room where before, all I would get is an intermittent 2.4Ghz signal.
