Connect Canon Pixma MG3620 Printer to Wi-Fi
The Pixma MG3620 can connect to Wi-Fi in minutes if you follow the right sequence: reset old settings, pick the 2.4 GHz network, use WPS or cableless setup, and verify with a test print from both a computer and a phone. This guide gives detailed steps for each option and highlights why certain routers, VPNs, or mesh systems can cause the Wi-Fi lamp to blink endlessly. Work through the sections in order and you will have a reliable wireless connection that stays online.
Reset Any Previous Network Data
Before reconnecting, clear stale Wi-Fi info. Hold Stop until the alarm flashes 15 times, then release. Wait for the MG3620 to restart. This ensures you are not fighting old credentials. Keep the printer close to the router during setup to avoid signal drops, and make sure you know the exact 2.4 GHz SSID and password; the printer cannot use 5 GHz.
WPS Push-Button Connection
The fastest method is WPS if your router supports it. Press and hold the Wi-Fi button until the power lamp flashes once; release, then press the Color button, then press the Wi-Fi button again. The Wi-Fi light should blink. Within two minutes, press the WPS button on the router. When the Wi-Fi lamp turns solid, the printer is connected. If it fails, make sure WPS is enabled on the router and try again with the printer near the main router instead of an extender.
Cableless Standard Setup with Canon Software
Download the Canon MG3600 series setup package. Run it, choose Wireless LAN Connection, then Cableless setup. The installer will prompt you to put the printer into pairing mode (Wi-Fi light blinking). It will then send the SSID and password directly. If the software cannot find the printer, temporarily connect a USB cable when asked so it can transfer the credentials over USB. Once complete, the Wi-Fi lamp should stay lit and the installer will register the printer on your PC.
Manual Connection Through the Control Panel
If you prefer manual control, enable wireless mode (Wi-Fi lamp blinking), then on your computer connect to the temporary network broadcast by the printer (Canon_ij). Open http://192.168.1.1 in a browser, enter your Wi-Fi name and password, and apply. After the printer joins your real Wi-Fi, switch your computer back to that network and install the Canon driver so Windows or macOS can find the device.
Add the MG3620 to Windows
Go to Settings > Bluetooth & devices > Printers & scanners and click Add device. Select Canon MG3600 series when it appears. If it does not, click The printer that I want isn’t listed and add by IP using the address from your router’s device list or by printing a network status page (hold Stop until it flashes twice). Install the full Canon driver for scanning and maintenance, not just the Windows Update driver. Print a test page to confirm.
Add the MG3620 to macOS
Install the Canon IJ driver for MG3600 series. Open System Settings > Printers & Scanners, click plus, and choose the printer when it appears. Set Use to the Canon driver instead of AirPrint to keep cleaning utilities. If it does not show, add via IP using the printer’s address. After adding, send a test print and run a scan from Preview to verify both directions.
Mobile Printing and Scanning
Install the Canon PRINT Inkjet/SELPHY app. Tap Add Printer, then Register Printer, and follow the prompts. The app may switch to the printer's temporary network—allow it, then return to your normal Wi-Fi. On iOS, confirm AirPrint sees the MG3620 by printing a note from the Files app. On Android, enable the default print service or Mopria to send jobs directly from Chrome or Gmail.
Fixing Blinking Lights and Offline Status
Blinking Wi-Fi light: The printer is waiting for credentials; restart the pairing process and verify the password. Alarm light after WPS: The router rejected the attempt—check that WPS is on and that the router is not in MAC-filter or guest mode. Offline in Windows: Delete the device, reinstall with the Canon package, and reserve an IP so the port always points to the right address. Disappears on macOS: Turn off VPN, ensure the Mac is on 2.4 GHz, and add the printer by IP if Bonjour does not find it.
Maintain a Stable Connection
Reserve the MG3620's IP address in your router to prevent sudden offline errors. Leave the printer in sleep rather than powering off so it can wake for jobs and run maintenance cycles. If you replace your router, redo the setup immediately—do not wait until you need to print. Keep firmware updated through Canon's tool, and print a page every couple of weeks to keep ink flowing so “connection issues” are not confused with clogged nozzles.
Quick Reference Checklist
- Reset network settings before pairing if you changed Wi-Fi details.
- Use WPS or cableless setup to join the 2.4 GHz network.
- Install the full Canon driver; avoid generic OS drivers.
- Add the printer by IP if auto-discovery fails.
- Reserve an IP in the router to reduce offline problems.
- Test from both a computer and a phone once connected.
Follow this plan and your Canon Pixma MG3620 will connect to Wi-Fi reliably, stay online, and be ready to print or scan from any device in your home.
