I can not find the password to connect to my Wifi 6 4-Stream Wifi Mesh Extender. 
I tried to follow the guide with steps but it is not working.

Did you look at the label on the device itself?

did you set it up using the wps option or the installation assistant? 

If you use WPS, it'll be the same password as the router

If you used the installation assistant, it'll be the password you set
