I would just like to say for the record: I love my Canon MX922!!! I had problems with the wireless connection as well, and I ended up just running a cable from the router to the printer and changing the configuration from wireless to wired. Problem solved. This may not be practical for you, in which case, you can ignore this comment.
However - everything about this printer works great! The ink is incredibly cheap (online with AMazon or other sources) and it does everything I need! It prints, copies in black and white and color, it faxes etc. etc. The color photos are awesome.
THe best thing for me is the ink is SOOOO cheap! Every other printer I have owned has been a money pit. This one was $99 and the ink is just a few dollars a cartridge.
NOTE: I do NOT work for Canon either!!
