@Spc what' kind of error message do you get from the RT-AX82U when you set it? (I am at work now and I cannot test it).
I tested on my DSL-AX82U and that worked out although on a guest network.
Try setting special password for wifi.
You type in your password and then space at the end, this is just an example.
Example:
"ThisIst3stPassword4 "
Copy this password without quotes, you'll see there's a space at the end of the password.
If you create a password with space at the end you'll get message:
Pre-Shared key can not contain white space!
If you use older firmware (asus official):
Version 3.0.0.4.386.43588
2021/07/29
Asus official link:
This is the last version that space at the end of the password still worked.
You can create a password with space in the end.
Password works on all clients.
After you reset the router space at the end of the password is gone, as asus doesn't write space at the end into nvram file.
nvram that gets loaded will load password without space at the end.
Maybe you can make this work on newer firmware / fork, or create a fork for 300438643588 that writes nvram file correctly.
I am using spaces in my password for better security from brute force attacks.
Thanks
