How do I change wifi address

You probably don't. What, exactly, are you trying to do?

Assuming you seek to change your client IP address on the Wi-Fi network… Via the Wi-Fi router DHCP server configuration and MAC address mapping, by manually assigning an IP address outside of the DHCP server IP address pool, or by turning off DHCP and switching over to a fully-manually-addressed configuration, among other means.

None of which probably answers your intended question, so—as Lyssa asks above—what problem are you trying to resolve?
