A SOHO had their wireless network breached on several occasions. The user turned off the SSID and enabled WEP encryption, but breaches are still occurring. Which of the following will improve…

Turning down signal strength reduces the coverage area slightly but does not address the fundamental cryptographic weakness of WEP encryption.

Replacing the WAP but keeping WEP encryption still uses a broken protocol and will not prevent breaches caused by WEP's inherent cryptographic flaws.

Changing the SSID and WEP key provides no lasting protection because WEP keys can be recovered by capturing a sufficient number of packets regardless of the key value used.

WPA2 uses AES (Advanced Encryption Standard) with CCMP, which is cryptographically strong and not subject to the RC4 stream cipher vulnerabilities that make WEP trivially crackable. Enabling WPA2 replaces the broken WEP protocol entirely, providing robust encryption that protects the wireless network against the passive traffic analysis attacks used to crack WEP.
