I have modified my original message after talking to Linksys (Router) support and Canon support.
My OS on my computer is Vista 64-bit. My Router is Cisco Linksys E4200. I have one desktop computer, the printer, 2 iphones and 1 iPad. Seems to lose connection when printer goes into sleep mode. Rebooting the printer (OR rebooting the router) reestablishes the connection temporarily , usually for 6-9 minutes, it has stayed connect longer, but it always goes offline. I currently have the computer connected with a USB cable, but would like to use it wireless. To print from the iPad or iPhones you have to reboot the router or printer, then print. I have been told by Canon that it is a router setting, and I have just spoken to Linksys support today and they say it is the printer going to sleep that causes the loss of connection so the solution is not to change the router settings. Seems to me, there should be some way to turn off the 'sleep mode' feature on the printer (Canon support says there is no option to turn it off). That would solve the problem. Does anyone have a slotuion, apparently neither Canon or Linksys do. Thanks, Guy

I found this same problem to be a result of my changing something (in my case, rearranging my office completely) in the wireless connection. I reloaded the Canon software CD and selected re-set up (or something like that) from the menu.
Doing so seems to have fixed the issue for me.

Don't give up too quickly. This may not be specific to your printer. I bought a new HP multifunction in October and it did the same thing. I could not recover it on the wireless network without powering it down and actually removing the power cord from the wall. Then it would come back until the next 'sleep' cycle. This was a documented HP issue and they were ignoring it. Printer went back and I bought a Canon MX922 which has worked for severl hundred pages of scanning, but now fails to scan a multipage 2-sided document to a .pdf file. Fails with Support Code 2804. Three different Canon techs worked several hours with me today, all very polite, courteous, knowledgable but we could not identify the issue - yet. Best we can determine is it may be some new scanning security in the financial docs I'm scanning.

Wireless printing ceased function (printer unavailable) suddenly for no apparent reason after many months of good functionality. No changes were made to the network. Now, all attempts to restore function have failed. I have spent several hours following all steps in a variety of articles. The printer is connected to the network but is unusable from any device. There is no reason this should be so complicated or difficult. I will avoid Canon printers in the future.

I have this same problem. After a longish period without printing (a day or so), the printer goes offline and the only way to find it is to turn it off and then back on.
I find that my Windows 8.1 Lenovo laptop and my Android phone cannot find the printer until I have cycled the power on the printer.
Any help would be appreciated. Thanks.
