Explanation
Changing the default password is the single most important first step when setting up a new router. Default credentials (e.g., admin/admin or admin/password) are publicly documented and universally known, making any router with unchanged defaults trivially exploitable. While changing the SSID and wireless channel are useful configuration steps, they do not directly address authentication security. Turning off DHCP adds administrative complexity without meaningfully improving security for a residential setup.
