Possible Causes for Wireless Network Access Errors

After setting up in a temporary office, Joe tries to access the company's wireless network.

Following several attempts, Joe is able to get an IP, but cannot access network resources.

Which of the following is the MOST likely cause of this error when trying to connect to the company's wireless network?

A.

Incorrect passphrase

B.

Incorrect power levels

C.

Incorrect workstation certificate

D.

Incorrect encryption.

C.

The MOST likely cause of Joe's inability to access network resources after successfully obtaining an IP address on the company's wireless network is an incorrect workstation certificate (option C).

Here's why:

When connecting to a wireless network, the client device (in this case, Joe's device) and the access point must perform a process called mutual authentication. This process involves exchanging certificates, which are digital files that verify the identity of each party.

If the client device does not have a valid certificate or has an incorrect certificate, the access point will reject the connection. This could result in the client device receiving an IP address but being unable to access network resources.

The other answer choices are less likely to cause the issue described:

• Incorrect passphrase (option A): If the passphrase was incorrect, Joe would not be able to obtain an IP address in the first place.
• Incorrect power levels (option B): Power levels refer to the strength of the wireless signal. While incorrect power levels could potentially cause connectivity issues, they are less likely to be the cause of the specific issue described in the question.
• Incorrect encryption (option D): If the encryption was incorrect, Joe would not be able to obtain an IP address in the first place.

Therefore, the best answer to the question is C, incorrect workstation certificate.
