does simply having ethernet ports increase wifi strength?
First off, I want to apologise for asking a question like this because I can see why it sounds dumb but I am just looking for confirmation.
Recently, my parents got a bunch of electricians to come a pull a bunch of thick blue ethernet cables from my main modem (living room) to 3 of our rooms. This means that now, there are 3 separate ethernet ports (see attached photo) in each room.
From what I know, these ethernet ports eases the need to stretch an ethernet cable from the living room all the way into my room if i am using my laptop/PC and want perfect connection. HOWEVER, my mum’s main purpose of getting this done was to increase wifi speeds so she could watch shows on her phone without lagging, because previously she had poor connection since the modem in the living room was quite a distance away.
I am having serious doubts now thinking about it, because extending a bunch of cables with ethernet ports does not really improve the wifi speed does it? Unless there is something I am not getting. I would appreciate some help, thank you.
