After public-works rotates the field-office WPA2-Personal passphrase, one inspector’s laptop fails authentication while peers succeed with the new key. The inspector insists the password was typed carefully. What common entry error should the technician check first?
Select an answer to reveal the explanation.
Short Explanation
Passphrases are case-sensitive—Caps Lock turns a good key into a wrong one. When everyone else connects after a rotation, suspect how that one user typed the new PSK. Flip Caps Lock off and re-enter the exact shared secret.
Full Explanation
WPA2-Personal passphrases are case-sensitive shared secrets. Accidental Caps Lock or shift errors produce an incorrect passphrase and authentication failure even when the user believes the string is right. Peer success with the new key localizes the fault to that client’s entry, not a global AP outage. Personal mode does not require EAP-TLS, and passphrase comparison is not case-insensitive.
