Canon Mg3620 Wireless Setup Not Working
When your Canon MG3620 wireless setup is not working, you've hit the most common frustration with this model. The MG3620 is a reliable home printer, but its wireless initialization can hang on a few specific issues. Nearly every connection problem traces back to one of three causes: a network mismatch, a router setting, or a handshake failure.
Manufacturer specifications show the MG3620 relies on the 2.4 GHz band under the IEEE 802.11n standard. Routers that default to 5 GHz or merge both bands under one SSID can confuse the printer during initial setup. That's the clue you'll need to identify which fix applies to your situation.

Quick Answer
A Canon MG3620 wireless setup not working usually resolves after you power cycle both devices. Unplug the router and printer for 60 seconds, then restart. Print a Network Configuration page to verify the connection.
Confirm your router broadcasts on 2.4 GHz only. The Canon PRINT app handles the rest.
Which Error Are You Seeing? “Printer Not Found” vs. “Offline” vs. “WPS Failed”
Before you dive into fixes, you need to name the exact problem. Here are the three most common screens.
- “Printer Not Found” during setup. The Canon PRINT app or your computer's add-printer wizard cannot discover the MG3620 on the network. This usually means the printer has no active IP address or is broadcasting on a different network.
- “Printer Offline” after setup. The printer appears in your devices list, but every print job sits in the queue with an error. This points to a communication break, often after a router restart or an IP address change.
- WPS setup times out. You pressed the WPS button on both devices within the window, but the printer never connects. This signals a misconfigured router or a WPS version mismatch.
Identifying your error cuts repair time in half.
The Simple Reset That Works More Often Than You Think
A full power cycle clears temporary glitches on both the printer and the router. Do this before any other fix.
- Unplug your router from power. Wait 30 seconds.
- Unplug the Canon MG3620 from power. Wait 30 seconds.
- Plug the router back in. Wait until all lights return to normal, roughly 2 minutes.
- Plug the printer back in. Wait for it to finish its startup cycle.
This reset gives both devices a clean handshake. It also preserves all your saved settings, so there is no risk of losing your network preferences. Try printing a test page before you move deeper into troubleshooting.
Your Decision Tree: Match Your Symptom to the Right Branch
Use your error code to pick the correct branch. Each path below targets a specific failure mode.

Branch A: The Printer Doesn't Show Up on the Network List
If your computer or phone cannot find the MG3620 at all, the printer is not connected to your network. The most likely cause is a band mismatch.
- Action: Open your router's admin panel, usually at 192.168.1.1 in a web browser. Look for wireless settings. Enable 2.4 GHz broadcasting and disable band steering or smart connect features. The MG3620 does not support 5 GHz.
- If that fails: Temporarily rename your 2.4 GHz SSID to something simple, like "HomeWiFi2G". Re-run the setup in the Canon PRINT app using that SSID.
Branch B: The Printer Shows Up but Shows as “Offline”
This means the printer has an IP address but your computer cannot talk to it. Often the printer's IP changed after a router restart.
- Action: Print the Wireless LAN report from the MG3620. Compare the IP address listed there to the IP address stored on your computer. If they differ, delete the printer entry from your computer and add it again using the new IP.
- Action: In your router admin panel, assign a static (reserved) IP address to the MG3620 based on its MAC address. This prevents future IP changes.
Branch C: WPS Button Setup Fails or Times Out
Not all routers support WPS reliably. Even those that do can have timing issues.
- Action: Check your router for a physical WPS button. Press it once, then press the Wi-Fi button on the MG3620 within 2 minutes. If it fails again, skip WPS. Use the Canon PRINT app with manual SSID entry instead.
- Action: Confirm WPS is enabled in your router settings. Some routers ship with WPS disabled by default.
Branch D: Wi-Fi Light Is Blinking or Off
The printer's Wi-Fi light gives a visual clue. A solid light means connected. A blinking light means it's trying to connect.
An off light means wireless is disabled.
- Action: If the light is off, press and hold the Wi-Fi button on the MG3620 for about 5 seconds. The light should start blinking. Then proceed with setup.
- Action: If it blinks indefinitely, the printer cannot find your network. Move the printer closer to the router during setup. Walls, metal, and distance weaken the signal.
| Symptom | Likely Cause | First Action |
|---|---|---|
| Printer not found on network | Band mismatch or wrong SSID | Enable 2.4 GHz, disable band steering |
| Printer shows as "Offline" | IP address changed | Assign a static IP in router settings |
| WPS setup fails | Router incompatibility or timing | Use manual SSID entry in Canon PRINT app |
| Wi-Fi light blinking continuously | Weak signal or network not found | Move printer closer to router |
The Mistakes That Keep the MG3620 Offline (Even After a Good Setup)
Even if you follow every step, a few common mistakes can undo all the work.
- Mistake 1: Using the wrong Wi-Fi password. The MG3620 is case sensitive. Re-type your password manually in the Canon PRINT app rather than relying on autofill.
- Mistake 2: Leaving the printer on an unstable router. A weekly power cycle keeps the connection stable and prevents gradual signal degradation.
- Mistake 3: Forgetting to disable VPN or security software. VPNs and over-zealous firewalls can block the printer's network traffic. Pause them during setup, then re-enable after the printer is added.
- Mistake 4: Using a hidden SSID. The MG3620 sometimes struggles to discover hidden networks. Temporarily make your SSID visible during setup, then hide it again afterward.
Avoiding these pitfalls saves hours of frustration.

The USB Cable Safety Net: When You Need to Start from Scratch
If the decision tree didn't solve the problem, the USB cable method is your fallback. It bypasses the wireless setup entirely and establishes a reliable baseline connection.
- Connect the MG3620 to your computer using a standard USB cable (USB-A to USB-B, the same type used for many external hard drives).
- Download the latest Canon PIXMA MG3620 driver from the official Canon support site.
- Run the installer. When prompted, choose "USB connection" rather than wireless. The installer will detect your printer.
- After the driver completes, add the printer in your computer's settings if it doesn't appear automatically.
Once the printer works over USB, you can optionally reconfigure wireless later through the Canon PRINT app. But honestly, if USB works and wireless continues to fail, a stable USB setup beats an unreliable wireless one.
Frequently Asked Questions
How do I print a Network Configuration page on the MG3620?
Press the Setup button on the printer. Use the arrow keys to navigate to "Device Settings" then "LAN Settings". Select "Print LAN Details" or "Wireless LAN Report".
The printer will print a page showing your SSID, IP address, signal strength, and connection status. This page tells you exactly where the printer stands on your network.
Why does my MG3620 only connect to 2.4 GHz and not 5 GHz?
The Canon PIXMA MG3620 was built to support the IEEE 802.11b/g/n standards, which operate exclusively on the 2.4 GHz band. It lacks a 5 GHz radio. If your router broadcasts both bands under one name, a feature called band steering, the printer may try to connect to the 5 GHz signal and fail.
Separate the bands in your router settings.
Can I set up the MG3620 without the CD?
Yes. Download the full driver and software package from the manufacturer's support site. You can find it under the PIXMA MG3620 product page.
The Canon PRINT app on your phone also handles wireless setup without any disc. USB cable users can install the driver directly from the downloaded file.
What does a blinking Wi-Fi light mean on the MG3620?
A blinking Wi-Fi light means the printer is searching for your network. It has not connected yet. If it blinks for more than a few minutes, the printer cannot find your router.
Move the printer closer, check that your router is on, and confirm your 2.4 GHz band is active. A solid light means a successful connection.
How do I assign a static IP address to my MG3620?
Open your router's admin panel. Find the DHCP reservation or static IP assignment section. Locate the MG3620's MAC address on the Wireless LAN report you printed earlier.
Enter that MAC address and choose a free IP address on your network. Save the settings and reboot the printer. The IP will now stay fixed.
Does the MG3620 work with Windows 11 and macOS Sonoma?
Yes. The MG3620 supports Windows 11 and macOS Ventura and newer versions. You need to download the latest driver from the manufacturer's support site.
Older drivers from the setup disc may not work with newer operating systems. Always download fresh software for the best compatibility.
