Q: After El Capitan upgrade, Canon Pixma printer not visible on network
I've seen a lot of smart questions and answers about an evident incompatibility between El Capitan and Canon's Pixma printers, so I'll start mine by saying that I've read everything and tried every prescription. My issue is that the two MacBook Pros in my household (mine and my wife's ) can't connect to our Canon Pixma MG7120 via wireless anymore. The printer is signed into the same network as the computers, and even confirms as much, but the computers don't "see" it anymore. One oddity I notice is that no IPv4 or IPv6 addresses show up on the printer's WLAN settings list.
I've spent time chatting with an Xfinity rep, who assures me my modem/router is fine. I've downloaded the latest Canon servers twice, I've wiped the settings from our Macs and tried again…nothing works. By this point the challenge is almost less about the inconvenience and more about the frustration.
Any suggestions?
MacBook Pro (13-inch Early 2011), OS X El Capitan (10.11.5)
