Setting up Wi-Fi on a Windows computer
The most reliable setup method is considered to be using a Windows computer and the official installation disc or downloaded driver. The setup program will automatically detect the printer in standby mode and prompt you to enter your wireless network settings. Run the file setup.exe or an installer downloaded from the manufacturer's official website.
During the installation process, select the "Wireless Connection" or "Wi-Fi Connection" option. The program will ask you to select your network from the list of available networks and enter the password. At this point, the computer will transfer the security settings directly to the printer. Canon G3400It is important that the Wi-Fi module on the computer is active at this time.
☑️ Check before installing the driver
If the automatic search fails, you can use the WPS method if your router supports it and it's enabled. Press the WPS button on the router, then press the corresponding button on the printer (often you need to hold the wireless button until the blinking pattern changes). This will allow the devices to exchange encryption keys without manually entering a password.
⚠️ Note: The installer interface may vary depending on your Windows operating system (10, 11) and driver version. Read the on-screen text carefully, as steps may have different names, such as "Network Setup" or "Wireless LAN Setup."
Using the Canon PRINT mobile app
Modern smartphones allow you to set up a printer without using a computer, which is especially convenient if you don't have a laptop handy. To do this, you need to download an app. Canon PRINT Inkjet/SELPHY from Google Play or the App Store. The app has an intuitive interface and supports the "Smartphone Setup" feature.
Launch the app and add a new device by tapping the "+" icon. Follow the on-screen instructions: the app will ask you to make sure the printer is in setup mode (the indicator light is flashing). Next, you'll need to select your Wi-Fi network from the list on your phone and enter the password. Your smartphone will transfer this data to Canon G3400.
What should I do if the app doesn't see the printer?
Make sure location services (GPS) and Bluetooth are enabled on your phone. On Android, the app requires location permissions to scan for available Wi-Fi networks in the area. Also, try restarting the app and running the search again.
Once the data transfer is successful, the printer's indicator will stop flashing and turn solid, indicating a successful connection. Now you can print photos directly from your phone's gallery or scan documents using the MFP's camera as a network scanner. Mobile printing opens access to many additional functions of the device.

Troubleshooting connection issues
Even if you follow all the instructions, you may still encounter situations where your printer won't connect to the network. One common cause is frequency incompatibility. G3400 series printers often only operate in the 2.4 GHz band, while modern routers can broadcast a 5 GHz network. Make sure you're trying to connect to a 2.4 GHz network.
Another problem could be a hidden SSID (network name). If your network is hidden, automatic detection may not work, and you'll need to manually enter the network name (SSID) through a dedicated settings menu or utility on your PC. It's also worth checking the MAC filtering settings on your router—it's possible the device is simply blocked.
| Symptom | Possible cause | Solution |
|---|---|---|
| The indicator flashes slowly | Connection standby mode | Search for the printer on your PC or in the app |
| The indicator flashes quickly | Connection or data transfer error | Check your Wi-Fi password and frequency band |
| The indicator does not light | The Wi-Fi module is turned off | Press the wireless button on the panel |
| Printer not found | Blocked by firewall | Temporarily disable your antivirus or check your network settings. |
In complex cases, it's recommended to reset the printer's network settings to factory defaults. This typically involves pressing and holding the wireless button until the indicator light flashes a certain number of times (often 15 times), then releasing it. This will clear the saved network profiles and allow you to start the setup process again.
Check signal quality and print a report
After you have managed to turn on Wi-Fi on the printer Canon G3400, it's recommended to ensure the connection is stable. You can do this by printing a network setup report. To do this, press the "Stop/Reset" button (the triangle in a circle) and hold it until the power indicator flashes a certain number of times (usually 10-15 times, the exact number depends on the firmware version), then release.
The report will contain information about the SSID of the network to which the printer is connected, the IP address of the device, signal strength, and firmware version. Signal level (Signal Strength) is a critical parameter; if it is low, network printing quality may degrade or the connection may be interrupted periodically.
If the signal strength is weak, consider moving the router closer to the printer or using a Wi-Fi repeater. Also, check for interference from metal objects or household appliances near the MFP. A stable connection ensures high-speed transfer of large files and photos.
How to find out the printer's IP address after connection?
The IP address can be found on the printed network settings report. It can also be found in the list of connected devices in your router's web interface. On a Windows computer, the address is displayed in the printer properties: "Device and Printers" -> right-click the Canon G3400 -> "Printer Properties" -> "Web Services" or "Ports" tab.
Is it possible to connect Canon G3400 to a hidden network?
Yes, this is possible, but it requires manual configuration. Using the standard PC setup wizard, select the "Enter the network name (SSID) manually" option and enter the exact name of the hidden network. Automatic scanning will not work in this case.
Does the G3400 support 5GHz connectivity?
Most G3400 series models only support the 802.11b/g/n standard, which operates in the 2.4 GHz band. If your router only broadcasts 5 GHz, the printer will not be able to see the network. You will need to enable 2.4 GHz mode in your router settings.
What should you do if you forgot your Wi-Fi network password?
The Wi-Fi password isn't stored in the printer's memory in plain text. You'll need to remember the password, look it up in your router settings (often written on a sticker on the bottom of the device), or reset the router and set a new password.
