Message "authentication error occurred"

[HeikoN]

I have set up the extender, the LED lights for the "on" and "WPS" light green aswell as the green light indicating range. Light on the router turns solid green and when I wish to connect any device to the extender the message keeps saying "authentication error occurred". What am I doing wrong?

Hello HeikoN - For us to understand more, please refer to page 6 of the user manual and tell us the LED status of all lights:
