Wifi password on box not working

[wireless]

Have two wifi networks in the house. Internet is working just fine. But if I try to connect to the Telus wifi router directly, either the -2.4g or -5g, I got a response saying the password is incorrect. But it’s the password on the box. Verified 400 times now! Why?
