I'm the latest to join the conversation on the Canon MX922 issues. For several months I was happy with my new printer and even stocked up on ink. I spent hours today reading through this forum and I keep shaking my head that this problem has been discussed for years! and Canon has yet to give a diffinitive solution.
I was glad to see that there have been some MAC solutions but those of us out here with Windows 10 are still looking. I tried the many suggestions, and have removed and reinstalled software several times, but still no lasting solution.
I too will be looking for another printer (not a Canon) because I really didn't want to settle for the USB cable method and hope to find a workable wireless printer.
Canon, you sure don't know how to support your customers or how to keep them happy!

I have a Canon MX 459 HARDWIRED to my PC WIN 10 and this solved the problem:
Push the OK button on the printer Twice ( You'll hear the printer beep ) BEFORE you send a document to the printer. ( Also make sure you don't have anytning waiting to print in the printing Que ) This wakes the printer up and it works every time for me.
I tried this fix on my daughter's MX479 hooked up to a MAC that is on Wi-FI but it didn't work. When I hard wired it to her MAC it does.
Hope it works for your model too!
I'm AMAZED that Canon can't come up with a simple "Wake Up and Reconnect" Option for WI-FI.

Message #43 in this thread fixes this problem!
No it doesn't.
Message #43 says to power off and then power on the printer. That's not what I call a viable fix. Power cycling the printer does get the printer back online for a few days. But it's a temporary work around and is an implicit confirmation that there's no permanent fix.
Message #43 also quotes message #35 which suggests disabling the DRX option. Is that the "fix" you're refering to? But as reported by myself and others, disabling the DRX option also does NOT work permanently. I suspect that disabling DRX only seems to work because when you change that option the printer resets its wifi connection. And it's resetting the printer's wifi connection (not changing the DRX option) that seems to make Wifi temporarily work again. The only permanent fix is to not use the MX922 via Wifi (which is what I ended up having to do). In other words, I've tried all the suggested "fixes" and it's still my opinion that Wifi on my MX922 is defective and there's no permanent fix. And that all the suggested fixes which cause the prnter to reset its wifi connection are only temporary "fixes" and have no real long-term effect on how frequently the MX922 loses its wifi connection.

Since my post of message #53 and your reply on #54, I have never had the problem again. Without getting into whether this shouldn't be necessary or the design of the printer, the fact is that assigning a static ip address outside the DHCP range absolutely solves the problem and allows anyone/device to print in wireless mode. One can contend all they want that this is a bad design and shouldnt be necessary but once again it does solve the problem. Try it and you can confirm a year from now. Peace
Just here to give creedence to spirestocks recommended fix of assigning a static IP to your device. If you look at all my posts here (wireless printers forum), you will see that I too also recommend this proceedure to fix this behavior. This is regardless of design or what you should or shouldn't have to do.
Dynamically assigned IPs have a lease time. This is a preset amount of time that a router "loans" an IP to a device connected to your network. When that devices goes to sleep, is turned off or leaves and the router doesn't "hear back" from it during the lease time, the router will reclaim the IP and put it back in the pool of available IP addresses the router hands out to new devices.
Devices come and go, they sleep, wake and sometimes get turned off for extended periods of time. A router is just doing it's job. All power cycling does (covered earlier) is force the device to connect and receive a new IP address. The router will hand out the next available address in its pool. If its the same one the device had before, you can print, but if another device has connected and been given the IP address you printer or computer thought it had... printing will fail.
Assigning a static IP, (also called) Address Reservation (assigning static IP by MAC address) is a way to ensure a device ALWAYS gets the same IP address, regardless of the amount of time it was last used, turned on of "seen" on the network. Its a simple way to ensure every device on your network will ALWAYS know how to communicate with your printer (or other device) because it it will always get the (same) static assigned IP.
Take heed. This is a "set and forget" recommendation. It takes 5 minutes. You do it once and you won't have to deal with this issue or wonder why you can't print again.
If this is not clear, see my other post here.

First thing I did when I bought this printer is assigned a static IP to it. I always have to turn the printer off and then on again after I send a job to it if it's been idle more that a couple of days. I'm looking forward to dumping this sorry printer in the near future.
