So I am in college and the internet we have here is kinda limited, my main issue is with my Amazon echo and other similar things, my thought was can i just buy a really cheap router and plug it into my ethernet port. Would I be able to set up my own wifi with that? I was probably going to get something like the TP-Link N300, because internet speed is not a issue for echo and things of that sort.
So my question is can I create any wifi just from any ethernet hookup?
