AirPort Extreme and Time Capsule don’t recognize the Wi-Fi password to connect

[Apple_Robert]

All of a sudden, I am having problems connecting to Wi-Fi on my Time Capsule or AirPort Extreme. Any time I try to connect, it tells me the password is incorrect, even though I am positive it is correct. I factory reset both units and tried and again and still get the incorrect password message on the phone or iPad.

I have AT&T U-verse and have the two above devices set up as a new network from the U-Verse.

I thought the problem might be iOS 15.1 X related and tried connecting with my OG SE on 14.8 and run into the same problem.

Anyone have any ideas how to solve this problem?

If you factory reset them you'd have needed to out in the SSID / password again, so did you put in exactly the same password as you'd used before the reset? If so and the reset didn't solve the problem, what I'd do is just use a temporary easy password (e.g. "password") that you can't possibly mistype then test to see if you can connect using that: if so you know all the basic stuff like hardware is working correctly, so you can then try again with a more complex password.

Thanks for the reply. I tried the same password before the reset as well as several other passwords. All were refused. I am positive that I typed correctly.
