My MX 452 printer keeps going offline. If I power it off, then back on it will work for awhile, but then randomly go offline again. My wireless network is fine for all other purposes and the printer is within 20 feet of a range extender. I have tried all the troubleshooting ideas at http://kbsupport.cusa.canon.com/system/selfservice.controller?CONFIGURATION=1011&PARTITION_ID=1&secu...
Any other ideas?
