Can't connect to wifi because of incorrect security key?

Network requires security key, so I put in the correct security key, but it refuses to accept it, saying that it's incorrect. Same thing on my other devices, wrong key.

Same thing on my other devices, wrong key. Heres some things I tried;

5) Manually setting up and connecting the wifi
