Caveat: I've never used any kind of Brother Device; I've always bought HP.

For various reasons, I've always configured utility devices on my home network
with a static IP Address. On my HP, I can then browse to it's Home Page to
check its status. Does you Brother have a web page?

What did I do in the fateful 30 mins yesterday afternoon!?
I have no idea really, but since it is not always visible in your Router
