One thing to note on a related point.
Re-setting the IP in the printer probably is a bad idea, even if Brother let me do that. That IP is set by the WIFI software in the router. When all came back after the power outage, the router assigned the DHCP IP address in the reverse of what they had been. The address of the printer and address of the laptop (100, 101) were switched.
Being adventurous and trying to undo that in the router WIFI setup proved to be deceptively easy to screw up. I lost communication with the router by assigning addresses contrary to what it had chosen. Routers do not like this, and mine refused to talk to me.
The paper clip reset hole in the back of the router saved me from network abyss.
