I cannot print using my Brother machine on a wireless network (Mac)

Wireless setup is requesting a WPS PIN to complete the setup

I get a TS error when trying to print on a wireless network.

My Brother machine could not be found over the network when I installed drivers on my computer.

I configured the "IP Config" method of the machine to "Auto" to assign an IP address automatically, however it was changed to "Static" unexpectedly. I get an error message that indicates IP address is not unique, or a document is printed out by the machine I didn't expected.
