At least now I know that I am not going crazy. This is a wireless printer that you might as well tie to your neck and walk around with it. Shameful that Canon will not respond, but I think that they are looking at tens of thousands of defective units in the market with no way to patch or fix them. Canon used to be the best name in the printer business and now all you get is a total plastic box that mechincally breaks easily and software that is released with little to no testing. There is a correlation between the low price of this high-end home printer and this massive failure of a whole product. Canon believes it must compete in the pricing game, and now "Canon quality" means very little. Too bad. Any recommendations out there for a reliable, high quality home/small business printer? (I also agree with the "one tray" comment---the model number went up but the functionality and quality went down.)

I'm in the same boat. My MX922 stops talking to the wifi network once it's gone to sleep. I have to either power cycle it or join it again to the WiFi network. Printer is a piece of garbage. I tried the "fixes" of turning off IPv6 and disabling the DRX setting. Hasn't made a difference at all.

I've had this problem as well using a new MacBook Air and new AirPort Time Capsule. Whenever the printer goes to sleep, the wireless connection is lost. A few weeks ago I was able to re-establish connection by tapping the Copy button to wake it up, but today even that didn't work. Whenver the printer went to sleep, I had to setup the wireless with my password again to to print.
I've now setup the printer using the AirPort Utility and it seems to be working. I learned about it on the YouTube video, "Easily Connect a WPS Printer to Apple Airport Extreme" at https://www.youtube.com/watch?v=YgjPBYThDeQ. It explains that you can add a WPS printer through Base Station menu of Airport Utility. No need to enter codes or passwords--just have the AirPort search for the printer, then have the printer do a WLAN Setup to look for a connection. After about a minute, they find each other and you're connected.
I'm keeping my fingers crossed that I won't lose the connection again.

I agree with other users this printer has become a giant doorstop after about 6 months of working correctly.
I have an Apple Airport Time Capsule for a router and OSX 10.10.4 on all our computers. I can no longer airprint with IOS 8.4 or via the wireless network from the computers. The last time the printer worked correctly was two weeks ago.
Up until that time it was fine. It is our 3rd and last Canon printer. It replaced an MX860 that had a 'heart attack' one day after 4 years of service. We are an Apple shop and I am checking with my Apple friends as to a recommendation.
Talked with Apple Care last week for over an hour and it ran for a while for one computer. Now it is back to 'coma mode' and nothing seems to wake it up.
The power cycle game worked with 10.10.3 but now NADA (nothing) with 10.10.4 and IOS 8.4
The total silence from Canon on this issue makes me believe they don't know how to fix it or don't care about Apple users. Are there any Canon engineers monitoring this forum?
My recommendation is to forget Canon and find another brand.
Good bye Canon and back to Costco with this door stop.

Solved problem took printer back to Costco and bought a new Brother printer recommend by my Apple maintenance person.
Been a loyal canon user for years but this problem of having the printer go into a coma was a real problem.
Canon keeps blaming the router but in looking at the thread we are all using many different routers. So Canon why don't you own the problem and stop blaming the user?

I think I have finally figured this out. I had this problem and thought it was the MX922 printer itself. Since I had a lot of ink left, I ordered another MX922. After installing the new MX922, same problem.... doh! But it clearly was not my computer or network.
I started looking through my router setup, and noticed that Canon had added specific DHCP entries (how did they get there?). Even though it looked like the entry was setup correctly, it was the only device specific DHCP entries. I removed the entry so it would use the default DHCP policies... and voila, no more sleeping MX922. It's been a few days now, and no more need to power off, etc.
FYI, I'm using an Airport Extreme, although I imagine they probably write a DHCP lease expiration policy into any router.
Hope this helps.

Can you elaborate a bit on the DHCP thing? I'm not a techie, but I'm reasonably intelligent. I have no idea what your'e talking about, and would really like to solve this connection issue. A new printer isn't in the budget at the moment, especially since I just bought a load of ink for this printer (that has been working just fine for over a year). I'm not using a router either, I'm on a wifi hotspot. Every other device in my house has no problem connecting (they are all apple as well).
