I'm going to be moving into a house of years of apartment living. The thing is that all the networking is in the basement and I have a 3 floored house. Now, I have bought a new Wi-Fi router (dual band ac) which is more powerful but not enough so that the 2nd floor gets connectivity. There's an ethernet port that runs up to the second floor; My question is, is there any way to connect my new router to the one on the second floor and make a seamless wireless network so that I don't have to change my network if I take my laptop upstairs. I know this is possible on a larger scale since my university already does this but I wanted to know if this was possible on a smaller scale.
Yes. There are a few possibilities but I suggest this:
I have a similar setup with 3 routers, but set it up a couple of years ago. I believe the above covers all the necessary steps.
