PIXMA MG3620 Reset/Change WiFi Connection


Hello Experts,

I have a friend with a Pixma MG3620 that was set up by someone else a few years ago on a wireless network. My friend changed ISPs a few months ago and now has a new router, but his printer was never set up to connect to the new access point.

Since the printer does not have a display panel, I can't quite figure out how to connect it to the new router. I looked at the documentation online, but I'm not seeing where those steps are.

How can I connect the printer wirelessly to the new access point/router? Can I change it, or do I need to manually reset the printer to its factory setting so that I'll be prompted to re-connect?

Thank you in advance for any assitance. Smiley Happy

Hi gtifeld,


Shadowsports provided some excellent information on connecting the printer to the network using a computer. 


Another option available is using an Android- or Apple-supported mobile device to connect the printer to the network. The steps below will assist you:


On the Printer


  1. Turn the printer off and back on.
  2. Press and hold the Wi-Fi button (A) until the ON ((B) lamp flashes, release the button.
  3. Press and release the Color Start (C) button.

  15. The app will attempt to register the printer.

Hi k9gardner,

I just ordered a USB cable to try to solve this problem for my MG 3620 (thinks my SSID is our old ISP, which it used to work with just fine). Emailed support; nothing. If the cable doesn't work, I'll have no choice but to throw this thing out the window and never buy a Canon product again. 😠
