The fastest way to connect your Canon MG3620
The Canon MG3620 connects to WiFi through its built-in menu system — you do not need a computer or special software to start. The printer has a small screen on top where you can navigate to the WiFi settings, enter your network name and password, and complete the connection in about five minutes. Once connected, any device on your home network can print to it without cables.
The printer comes with a WiFi button (marked with a wireless symbol) on the front panel. Pressing this button puts the printer into pairing mode, which is when it listens for your network. You then tell the printer which network to join and provide the password — the same one you use to connect your phone or laptop to WiFi.
Key Takeaways
- Press the WiFi button on the printer's front panel to start the connection process; the WiFi light will blink to show it is searching for networks.
- Use the printer's menu screen to select your network name from the list and enter your WiFi password exactly as it appears (uppercase and lowercase letters matter).
- Once the WiFi light stops blinking and stays solid, the printer is connected and ready to receive print jobs from any device on your network.
- If the connection fails, restart both the printer and your WiFi router by turning them off for 30 seconds, then turning them back on.
- You may need to install the Canon print driver on your computer or phone after connecting, depending on your device type.
Step-by-step connection using the printer menu
Start by making sure your printer is turned on and your WiFi router is nearby and working. Press the WiFi button on the front of the printer — it is the button with the wireless symbol. The WiFi light next to it will begin to blink, which means the printer is now searching for available networks.
The printer's small LCD screen (the display on top) will show a list of WiFi networks it has found. Use the arrow buttons below the screen to scroll through the list until you see your network name — this is the same name you see when you connect your phone to WiFi. Press the OK button to select it.
The printer will then ask you to enter your WiFi password. Use the arrow buttons to move through the on-screen keyboard and select each letter or number of your password. This step is where most people get stuck: the password is case-sensitive, meaning uppercase and lowercase letters are different. If your password is "MyNetwork123", you must enter it exactly that way, not "mynetwork123". Take your time and check each character before moving to the next.
Once you have entered the password, press OK. The printer will attempt to connect. If successful, the WiFi light will stop blinking and stay solid. If the light turns off or blinks red, the password was incorrect or the network is not available — try the process again and double-check your password character by character.
What to do if the WiFi light stays off or blinks red
A solid red or continuously blinking WiFi light means the printer could not connect. The most common reason is an incorrect password. Go back to your router or the device you use to connect to WiFi and confirm the exact password — copy it if possible so you do not mistype it when entering it into the printer.
If you are certain the password is correct, restart both devices. Turn off the printer completely, wait 30 seconds, and turn it back on. At the same time, unplug your WiFi router, wait 30 seconds, and plug it back in. This clears temporary connection problems that sometimes prevent devices from finding each other. Once both are back on, press the WiFi button on the printer again and try the connection process a second time.
If the printer still cannot connect after a restart, move the printer closer to the router temporarily. The MG3620 has a limited WiFi range, and thick walls or distance can prevent it from seeing the network. Once it connects successfully, you can move it back to where you want it.
Installing the printer driver on your computer or phone
After the printer connects to WiFi, you need to install the Canon print driver on any computer or phone you want to print from. The driver is software that tells your device how to send print jobs to the printer. Without it, your device will not see the printer as an option.
For Windows computers, visit the Canon support website, search for "MG3620", and read the driver for your Windows version (Windows 10, Windows 11, etc.). Run the installer file and follow the on-screen prompts. For Mac computers, the process is the same but you will read the Mac version of the driver.
For iPhones and iPads, the printer should appear automatically in the print menu once it is connected to WiFi — no driver read is needed. For Android phones, you may need to read the Canon Print app from the Google Play Store. Once installed, the app will find your printer on the network.
Printing your first document over WiFi
Once the driver is installed and the printer is connected, printing is straightforward. Open the document or photo you want to print on your computer or phone. Click or tap the print option (usually under File menu on computers, or a share button on phones). A print dialog will appear showing available printers — select your Canon MG3620 from the list.
Choose how many copies you want and any other settings like paper size or color, then click or tap the print button. The document will send to the printer over WiFi, and the printer will begin printing within a few seconds. If nothing happens, check that the printer has paper and is turned on, and that the WiFi light is still solid.
Connecting multiple devices to the same printer
Once the printer is connected to your WiFi network, any device on that same network can print to it — you do not need to repeat the WiFi connection process on the printer. Instead, install the Canon print driver on each new device (computer, phone, or tablet) and the printer will appear in the print menu automatically.
This is one of the main advantages of WiFi printing: everyone in your household can print without plugging cables in or moving the printer around. The printer stays in one place and handles print jobs from multiple devices at the same time, queuing them in order.
Troubleshooting when the printer stops responding
If the printer was working but suddenly stops responding to print jobs, the WiFi connection may have dropped. Check the WiFi light on the printer — if it is off or blinking red, the connection was lost. This sometimes happens if the router restarts or if the printer was turned off and back on.
The quickest fix is to restart the printer: turn it off, wait 10 seconds, and turn it back on. The WiFi light should return to solid within 30 seconds. If it does not, press the WiFi button again to reconnect. If the printer still will not connect after a restart, restart your router as well by unplugging it for 30 seconds.
If you are still having trouble after restarting both devices, check that your router is working by connecting your phone to WiFi — if your phone cannot connect either, the router itself has a problem and needs attention. If your phone connects fine but the printer does not, the printer may need to be reset to factory settings and reconnected from scratch.
Frequently Asked Questions
Do I need the USB cable if I am using WiFi?
No. Once the printer is connected to WiFi and the driver is installed on your device, you do not need the USB cable at all. The cable is only used if you want to connect the printer directly to a single computer, which is slower and less convenient than WiFi.
Can I connect the printer to a 5GHz WiFi network?
The Canon MG3620 only works with 2.4GHz networks, not 5GHz. If your router broadcasts both, make sure you select the 2.4GHz network name when connecting the printer. Many routers have separate network names for each frequency — check your router settings or the sticker on the back of the router to see which one is 2.4GHz.
What if I forgot my WiFi password?
You can find your WiFi password by connecting another device (like your phone) to the network, then checking the WiFi settings on that device. On Windows, go to Settings > Network > WiFi > Manage Known Networks and select your network. On Mac, hold Option and click the WiFi icon in the menu bar. On phones, the password is usually in the router settings, which you can access by typing your router's IP address into a web browser.
How far away can the printer be from the router?
The MG3620 typically works reliably within 30 feet of the router with a clear line of sight. Walls, metal objects, and distance reduce the signal strength. If the printer is farther away or in a different room, move it closer to the router to establish the connection, then you can move it back once it is working.
Can I print from my phone without installing an app?
On iPhones and iPads, yes — the printer appears in the standard print menu without any app. On Android phones, you may need the Canon Print app, though some devices can print without it if the printer driver is installed through your phone's settings. Try printing first without the app; if it does not work, read the Canon Print app from Google Play Store.
