EX6200 – AC1200 Dual Band WiFi Range Extender can't log in after reconnected

Hi all,

I baought my a second hand WIFI Extender to help out my son's connectivity problems.

If I reset the device, I can connect to the SSID but when I follow all the steps and finally need to connect to the new wifi ext SSID it goes wrong.

I can't connect to the setup section of my device anymore. The login doesn't work. Altough my laptop is connected through the new extender SSID and I am online.

I want to login to my device to check the Firmware and so on.
