Canon Pixma MG3122 printer/scanner: Wi-Fi won't detect

[v-grimalkin]

I know this is the most obvious question but was the printer actually setup for wireless with putting in the passphrase and/or wireless turned on in the printer settings. I just know using HP printers seems to make things easier and also setting a default IP on the printer when using networked/wireless printing. I have had printers not show up on the router because they changed IP randomly.

This could very well be part of the mess, since up until a couple months ago, the printer and scanner were working fine via wi-fi using Mint Cinnamon 17.3, but a some point (no doubt a network package update) the wireless connecting quit.  The printer was originally installed while the notebook OS was Windows 7.  When I switched to Linux, the only problem encountered was the scanner's wireless connection which was solved somehow through a setting in the firewall, if I recall.

Jerry kindly spent over an hour with me trying to fix this issue and suggested I reinstall the Canon using a Windows pc; problem is, I don't have one, and I have promised myself never to purchase another Microsoft product.  I suppose I should stick an "ABANDONED" header on this thread. 

I really appreciate all the suggestions and especially Jerry's dedication to helping a clueless newby.
