Brother 3150CDW wifi printer goes offline after reboot in Windows10

I have a Brother 3150CDW and works perfect.
When I reboot my laptop with Windows 10, I get the printer offline.
It's not a printer's disconnection from the WIFI, but a Windows problem: If I go into the control panel, and I seek the printer's URL, and I enter the printer via the web, I can access it, I can see it's IP address to be the one that is assigned to it by the DHCP, and I can launch a test-page printing from the web. This proves the "network" works, otherwise the web server of the printer would not be accessible.
From inside we can browse, so the printer "is there":
Instead, when printing from the windows, the spooler keeps telling me that the printer is offline.
I've tried everything, from forcing the usage as offline, to restarting the spooler service.
And nothing. It keeps offline ("Sin conexión" in Spanish).
The menu connect is disabled in the windows spooler for this printer:
The port is a WSD with a weird name (seems to contain an UUID in it):

How can I make the printer go online?
