Explanation
Resetting the wireless passphrase and enabling WPA2 encryption secures the wireless network, which prevents unauthorized external users from gaining network access to the router in the first place. Without network access, an outside entity cannot reach the router's management interface to modify or inject malware into the firmware. WPA2 is significantly stronger than older protocols like WEP or WPA with TKIP.
