You get a call from a small business customer saying that she periodically has a problem logging in to her office’s wireless access point (WAP) to make configuration changes. To make configuration changes, she’s connecting her computer to the WAP using an Ethernet cable. She is sure she is using the correct username and password. Assuming the customer is using the correct authentication credentials, what could be the problem? (Choose two.)

A. The access point needs a firmware update.

B. The cable between her computer and the WAP is broken.

C. WEP is interfering with authentication.

D. Sometimes she has caps lock on when typing her credentials.

Solution

A and D. An access point, like any other computing device that runs software, is subject to bugs that cause errors in behavior. One such possible bug can result in an authentication failure. Updating the WAP’s firmware to the latest version can apply whatever bug fixes the WAP manufacturer has created. Also, sometimes a person can leave caps lock on when typing a username and password, resulting in authentication failure.
