This seemed to fix my problem:

With some routers, if activity is not detected on a device after a set period of time, the device will be removed from the routing table. When the printer enters standby, it also enables discontinuous reception to save power. This might cause the printer to be disconnected from the router when you attempt to print again.
To disable this feature:
If the device is still disconnected after a long period of inactivity, I recommend contacting your router manufacturer for some additional options or settings you can change within the router itself.

Sorry, but this is a printer problem, I have 7 other devices being wirelessly routed, at any given time I may not be active on them for far longer than my printer. The LAN DRX setting was suggested in other email threads not related to this one. It did not work in my case.
The printer, when it goes into standby mode, will indeed drop its connection, once that is done, I don't think it is the responsibility of any router to assume anything other than the device went away. At this point, I think, is where the printer fails, that is, when coming out of standby, the printer has no idea how to reconnect to the network, the only way it knows how to do so, is for a complete power cycle to communicate with the router. Unfortunately, it also means, once the connection is dropped, none of the devices have any way to communicate with the printer to wake it up, as far as they are concerned, the printer no longer accessible.
I have switched the printer from wireless to direct and have no issues with the printer losing network connectivity. The printer will wake up immediately when a print is requested by any of my devices.
As far as the response from the Canon engineer on the 3rd, it was disappointing. As I indicated in my responses, The printer works when wirelessly connected. Sending instructions on how to connect wireless was irrelevant.

You can add me to the list of MX920 printers that drop offline (wireless) with inactivity.
I tried the DRX setting, no help.
If anyone has a link to the firmware upgrade, that would be great.
The printer works really well, but this problem seems so fundamental. WHy not have an option to disable standby?

Rob, these are the steps I used for the firmware update.

I agree, the firmware update seemed to have worked for a little while but the problem has returned. Not understanding how this is such a problem when our previous Canon on the exact same router had ZERO issues.

I have the same problem! It's super frustrating to have to reboot a wireless printer in a closet in another room every time I need a printout. Once my Mx922 goes to sleep it might as well power off! It happens from my mac and windows machines, it's not the OS, machine, or router...it's the printer.
Canon, this is a real issue, please help!
