Printer connected but can't connect on app

Hi there, 

Well, I have a Canon G3110 and when I setup the initial config. I had some troubles because the printer connected to the router (and appears on it, with the correct MAC) BUT when I have to find it with my computer it didn't show up, so I had to add it whit the ip given by the router, and solved. Now, same happens with the Android app "Canon Print" and again, I already connected (again?) the printer to the Wi-Fi but when the phone have to find on it in the list, dont show up. But I can´t fin any way to put in with the exact IP again.



Btw, sorry foy my bad english, hope someone can help me.

Best regards.

PD: On the router I reserved an IP to the printer and also disabled de IPv6 in the printer.
