Why would a network technician change the wireless router IP address to a different private IP address during initial installation?

• to limit the number of devices and users that can attach to the wireless network
• to enable the router to become the DHCP server for the network and to perform NAT
• to strengthen the network mode login security and encryption settings
• to ensure that users will have to manually configure the network name in their wireless clients
• to decrease the likelihood that someone could access the router using the default settings
