I recently replaced our modem, but the router is the same. I have always been able to print wirelessly from both the desktop and laptop comuters. Since replacing the modem, my desktop computer (connected to the modem) now tells me the printer is "offline." I use Microsoft Windows 10 on a Lenovo computer. I know the printer is visible on the network because I have no problem printing wirelessly from my laptop. I can also print from the desktop computer if I connect to the printer via USB cable. But that's not practical day to day because they are too far apart to keep the cable attached all the time.
So far I have...
Reconnected the printer to the network
Restarted the modem, router, and printer
Uninstalled the printer drivers and reinstalled from the original CD. The drivers got installed, but the process halted when the network couldn't find the printer
Fiddled with the COM ports based on some online instructions
Called my internet provider who said it's probably a router issue but because it's not their router, they were not able to help
Looked through Canon's Community responses and tried some that were different from what I already tried and were within my skill comfort zone. Nothing has worked.
Can anyone help??

A modem replacement would not cause your printer to show as offline or disconnected. The two do not interact and are unrelated. Your router is the "conduit" on your network and what is respnsible for managing connectivity and communication between devices on your network.
@spirestock has made a good suggestion in regards to assigning your printer a static IP address. If the IP of the printer changes on an ongoing basis, pther devices can have difficulties "finding" it as it will be a "moving target" or destination.
The good news is this, setting a static IP only has to be done once. Its a set and forget procedure.
You can do it on your router, or the printer.

Thanks for the follow up Rick! Yes, once I assigned a static ip address to printer above DHCP range I have never had a problem, going on half a decade ago to this perceived problem that has effected so many people; yet, this one fix works. Thanks again, Paul
