I see! Thank you so much for the detailed response… Regarding the wired backhaul however, I was wondering if you have some ideas regarding how it works… Would it required extensive setup? (eg drilling and linking cables etc)

I have no lan ports that are connected upstairs, as i was told by the electrician previously that it is not worth setting up the lan ports due to them being the previous generation(?), and installing the new lan port wouldn’t solve the internet speed problems…
