Greetings,
Your internet provider has nothing to do with the printers operation. The device has a 1 yr warraty from Canon. If you have purchased a CarePak, then there is additional support for service beyond the 1 yr warranty. If your device is covered, I would absolutely contact Canon.
Best way, is My Canon
It would be difficult to help troubleshoot the printer's operational issues if you can't get it connected and communicating with anything.
The device can connect via ethernet or wireless. Its one of the few Pixma devices that supports dual band wireless, 2.4 or 5G. Its requires WPA2 / AES encryption. You can also print from a Android or iOS device if both are connected to the same network.
The first thing to do it get the printer connected your network. I would suggest assigning it a static or reserved IP on your router. This way other devices on your network can always find it. Once this is done, we can try to look at the other issues you are experiencing.
Support directly from Canon is available if you are within the first year of ownership of have a CarePak. If you don't, there is a small fee to receive support. Talking to fellow users here is free 😄. Please let us know how you'd like to proceed.
