Blackberry q10 wi-fi connection problem

Hi, when i try to connect on my own router wi-fi from home to my blackberry q10 i always get this message "Unable to Authenticate against the network, Verify saved network security settings " and i don't understand why?! All my other devices work perfect (iphone, windows) just my bb doesn't work. Does anyone know what the problem might be? Answer please!

Its sounds like it can't match the security credentials. These can usually be cleared/reset by 1) FORGET the connected signal, + turn router on and off again. 2) re-connect where it asks you for the passkey value and generates new credentials.
