Hello plemans
my extender is connected to --> Nighthawk AX6000 AX8 8-Stream WiFi Router (RAX80)
I did not use WPS for the setup, i used the NightHawk Android Application.
I've, in the past, already done some factory resets & setups without issues.

Make sure you're not using wpa3 on the router.
Try the installation assistant and not the app

i'm not using WPA3 but WPA2-PSK [AES]
i just did the factory reset again, ... and only the 5Ghz channel is working 😕 with internet
How come such a thing happens suddenly ? ... how can i check whether or not it's related to the latest firmware update ... i see there a recent one, and my extender has the latest firmware, maybe something went wrong .... it's really annoying !
I'm blocked for many things (for devices not supporting 5Ghz 😞 ....
Is it possible to downgrade ?

You can downgrade the firmware. Just use the manual update process but instead of using the latest, you use the older version.
it looks like its setup properly according to your photo.
Are you using any special characters or spaces in the ssid/password? if so, try removing them
