I have just set up a Canon Pixma MP620 to work wirelessly over wifi on my network. The printer works fine when it is right next to the router (a Netgear). However, when I move the printer to another room away from the router, the signal strength goes to nothing/unstable and I cannot print wirelessly. My MacBook retains full wifi signal strength in this same room so the router coverage would appear to be okay. Is there anyone using this printer over wifi where the printer is in a different room to the access point/router? Is there something wrong with my printer? Thank you.
