Regardless of whether the wireless printing problem/lack of connection originated from the wireless drx setting, IPv6 setting, location field not being filled out, or dynamic IP assignments being assigned by router, I am hoping that the following procedures will always solve the wireless problem. I can only provide this after going through printer offline, printer error, printer being used by another user, etc and figuring out why the LAN setting list under the printer touch screen confirm LAN Settings was not highlighted. The PIXMA MX 920/922 can be utlized using the USB port, a wired LAN/network adapter, or wireless WLAN connection. For each method desired, the correct method (USB, wired, wireless) has to be selected in the printer touch screen: Setup>Device Settings>LAN Settings>Change Wired/Wireless and setup with that method and CANON port (within print icon on computer) coinciding with the method desired. In each case the printer icon in the devices and printers on computer has to reflect the correct port and associated IP for that port. In my case, the WPS and auto detect IP did not work during the setup/initialization process. I had to go to the computer network sharing center and look at the wireless network adapter and find the IP address for the IPv4 address, subnet, and gateway because these fields have to be input manually if you use the printer touch screen and you have to manually input password for the SSID through the printer touch screen via Setup>Device Settings>LAN Settings>Other Settings>TCP/IP>IPv4. When you print out the LAN Settings, you will see enable for either the wireless or the wired option depending on which is set on printer in the change wired/wireless printer touchscreen option on printer. Once I knew the IPv4 settings for both the router wireless adapter and the LAN wired connection, I did the following: I made sure that the firmware was most recent, the DRX setting and IPv6 were disabled and I went to Canon website and downloaded most recent drivers for my operating system Windows 10 with 64 bit which was automatically detected by Canon website. I had to do this three times for each mode/method to obtain a port: USB, Wired, and Wireless and in my case even though I chose wired and then the wireless method, I had to use the USB connection cable (USB cable from computer to printer) even though I was installing the wired or wireless option as the process did not automatically connect to the router even though the blue light was on the printer and the wireless method was enabled. Each time a Canon Network port with IP and MAC address was created for each driver download for the specific method so I had three icons in the printers/device on computer. You have to make sure that the port, IPv4 addresses and MAC address for type of connection all coincide. When you update the drivers and go through the initialization process as mentioned in previous threads, once you choose the method for connection, you will have to manually change the IPv4 addresses to match the port and method which is provided in network information during the initialization process. If the IPv4 address does change down the road, you just have to go to the printer touch screen and manually enter the IPv4 addresses if you know the port and the MAC address is still relevant. I updated each printer icon in computer printers and devices to reflect name that includes whether usb, wired, or wireless and the IP address that originally made it work. If for whatever reason you can not get wireless to work, you can always run a yellow network cable from router to printer, choose the wired method and still be able to wirelessly acesss router and print through the wired method if the wired method is chosen on the printer touch screen under LAN settings. When wired is chosen the LAN setting list will be higlighted and printer printout will show wired enable and when wireless is chosen, then WLAN setting list will be chosen and the printout will show enable for wireless. You know it will succeed when you see IPv4 addresses in the confirm LAN settings that matches the port method (Wired, Wireless) knowing each printer icon should reflect the method or at least know, you have to configure the port for the proper method you want to print via the icon in the computer printers and devices. Again, I had to use the USB connection cable to establish both the wired and wireless connection after I knew the IPv4 addresses for each WLAN (wireless) and LAN (wired) connection. I know this is long but should work each time for not having a wireless connection
