Here I tend to use the powerline pairs like this setup.
Your method might work if you configure it but most clients don't want to work so hard.
I live in a 3 storey house. My modem (which includes an integrated router) is located the first floor. The internet speed is 60mbps. On the third floor, I was getting a very low wireless signal, making it very difficult to browse on the internet, As such, I decided to buy the Netgear WFi Extender AC1200 and I placed it on the third floor. Both my Mac and my PS4 are located on the third floor and are now wired directly into the Netgear WiFi Extender AC1200. I can now can speeds up to 25mbps on the third floor, which is signifanctly better, but not optimal.
I have read that you can get higher speeds with powerline adapters such as the Netgear Powerline 1200 (1 port). Therefore, I thought that I should change my configuration to a powerline network instead, but the issue is I want a good wifi reception for my portable devices (Iphone, Ipad, etc.) on the third floor. I thought of a solution but I'm not sure whether it works:
1. Setup powerline adapters: one connected to my modem/router and another one connected to the wall outlet on the third floor
2. I would then run a wire from the Powerline Adapter on the third floor to my Netgear Wifi Extender AC1200 located on the third floor
3. I would wire my Mac and PS4 to the Netgear Wifi Extender AC1200 (all on the third floor)
4. Netgear Wifi Extender AC1200 would also be used as a wifi access point for portable devices.
In other words, I'm wondering whether I can use the Netgear Wifi Extender AC1200 as an access point that is wired to my powerline network connection. If that doesn't work, I also have an Apple Airport Extreme and a linksys wifi router that I don't currently use.
Any help would be greatly appreciated.
