Hello!

What is the best TP-Link router with Wi-Fi range Extender mode. I mean I have my main ISP router on the second floor. I'm living on the first floor and I don't have an option co connect routers via cable by floors. I want to connect my TP-Link router by Wi-Fi to my main ISP router, then use my TP-Link like range extender both for cable and Wi-Fi connections on my floor (same Wi-Fi connection for connection with my main ISP router and devices on my floor). Now I use TL-WR841N router with Wi-Fi range extender mode, but it is weak, connection is broken often. I'm looking for better (the best possible) TP-Link router to replace it in this mode, can you help me? I know only a few TP-Link router have that option... Thanks in advance.
