I recently bought a Pixma ip8720 and have tried for 3 days now to get it to work wirelessly without any success. It works fine when connected via USB, but just will not connect via wifi.
When I print the network config page it shows that it's connected to the network and when I use WPS my router says the device has successfully been added, but when I scan for printers nothing ever shows up. When I use the Canon installer it gets all the way to the connect to network screen, searches for 1-2 minutes, then says it cannot detect the printer. I've even tried manually added it, but no luck so far. I have tried installing it both cordlessly and while connected via USB and the exact same thing happens.
I'm starting to think there is some sort of network security issue. I even disabled my firewall in Windows to see if that helped, but it didn't.
