Canon PIXMA MG3620 Wi-Fi Setup

The Canon PIXMA MG3620 has a model-specific wireless setup path. Use the printer’s own controls and the current Canon setup software rather than repeatedly resetting unrelated settings.

Set up Wi-Fi

1. Turn the printer on and let any cleaning/alignment finish.
2. For cableless setup, hold the Wi-Fi button until the ON lamp flashes, press Color, then press Wi-Fi; continue when the Wi-Fi lamp flashes quickly and the ON lamp remains lit.
3. Continue in Canon PRINT or Canon setup on the computer/phone; if iOS asks, join the temporary Canon_ij_ network and return to Canon PRINT.
4. For WPS, place the printer in WPS connection mode and press the router WPS button within the documented window; completion is indicated by steady Wi-Fi/ON lamps.

If the printer is not discovered

1. Confirm the router is on and the phone/computer is connected to the intended network.
2. Temporarily avoid guest networks or VPNs that can block local-device discovery.
3. Check the printer’s network/WLAN status or connection report where this model provides one.
4. If the printer is already connected but one computer cannot find it, repair/re-add the printer on that computer instead of resetting the printer network first.

After changing router or password

Run this model’s wireless setup again with the new SSID/password. A driver reinstall alone cannot reconnect a printer whose saved router credentials are no longer valid.

Before calling it a driver problem

Prove the network layer first. If the printer itself is not connected to the router, fix Wi-Fi. If it is connected and another device can print, focus on the affected computer’s queue/software.
