So in my family living room with our living room PC we have our (comcast) router and WiFI router (ASUS RT-AC66W). But once you get to the backroom, upstairs and outside in the garage, the signal strength is weak at best. I'd really love it if I could buy something that improves the WiFi signal strength on our property. If I had to disconnect from the living-room WiFi and connect to the second, I wouldn't hate it but I'd love it if you could walk from one area to the other and it seamlessly pick up whatever the stronger signal is. Just so you know, both the backroom and upstairs have Ethernet ports available to be plugged into. So, what (if anything) can I buy to achieve this? And along with buying it, do you have a site that provides a guide on how to set this up? Thank you for any help you can provide!! ------------------------------------------- Current Question: Okay so I got this switch: https://smile.amazon.com/TP-Link-TL...L-SG1008D&qid=1558053467&s=electronics&sr=1-1 and I got the Unifi AP AC Lite. My question now is; A) I should change my Asus WiFi router into an AP in conjunction with setting up the switch and Unifi AP, right? B) Assuming the answer to A is yes, should it be as simple as this: https://www.asus.com/us/support/FAQ/1015009/ to turn my Asus WiFi router into an AP?
