I have a wireless Canon MG3150 all in one printer that has always worked fine until I changed the pass-phrase for our WIFI connection. Now the printer always says it is offline. I looked through the settings and couldn't find anything for the wireless and so unistalled and reinstalled the printer completely. That worked fine and I was able to print but now that my laptop has been off, the printer is now showing as offline all the time again. I also cannot scan though the photocopy function is working and the printer shows up in Windows ok and working. I have Windows 7 Home Premium.
