I live in two floor house. I have TP-Link Archer C1200 Router on 2nd floor, and TP-Link Wifi Extender RE350 on 1st floor. I got the extender to connect to the router and shows blue LED.
The problem is that the phone does not connect to the stronger wifi when I move from one floor to the other. It just stays with the same wifi that was connected initially (Currently the extender and the router uses same SSID). I heard that having the same security for both router and the wifi extender should solve the issue, but I have no idea how to force the TP-Link wifi extender to configure as WPA2 (Currently it's configured as WPA/WPA2-PSK).
And please don't tell me to use different SSIDs, as I have tried this and I had to manually change the wifi connection on the phone/laptop, and I do not want that. If anyone has an idea on this, please help.
