MG3250 not connecting & printing via WiFI on Mac OS Sierra

[qabel]

Hello,

I've been using a MG3250 printer for the past three years via WiFi, starting with OS X Mavericks. Back then, I'd configured the WiFi connection using the setup application Canon provided. After switching the ISP a few weeks ago and having to reconfigure the WiFi connection, the printer worked fine until today. Apparently, it lost the connection and won't reestablish it - it stays shown as not connected.  Printing via USB works fine, using the Canon IJ Network Tool from 2013 to configure the WiFi connection - I believe - also does, because it does recognize the printer when connected via USB and it - apparently - also loads the configuration onto the printer. I've tried connecting it via WPS, which did not work, and given that the initial setup application doesn't work on Sierra anymore - it doesn't start -, I haven't been able to try the Standard Connection Method.

Any ideas on how I might solve this problem?

Thanks.
