Asus RT-AX88U Can't set SSID password

[rt2016]

Hi all,
I have just configured my new Asus RT-AX88U and it works fine over all. But when I try to get the Wireless running on my Ubuntu 20.04 Laptops I can select the 5 GHZ and when pressing connect nothing pop-up where I can type in the password.

Has anybody a hint for me, this is somehow very anoying ;-). Kids are claiming . I have also upgraded the WIFI modul's to Killer AX1650. Under my old RT-AC88U everything works smothless.

best regards

Are you using the same SSID's? If so, 'forget' the connection and then re-associate with the new router.
