Modern inkjet MFPs of the Pixma G series from Canon eliminate the need for cumbersome cables and being tied to a single computer. Wireless printing allows you to scan and copy documents from any device in the home, be it a laptop, smartphone, or tablet. However, initial setup wireless connection often raises questions among users who are not familiar with the nuances of how the printer's network modules work.
The process of activating Wi-Fi on the model G3400 Requires a specific sequence of steps that must not be interrupted. Unlike older models, this one uses a specialized setup mode activated by a combination of buttons on the control panel. Following the steps correctly ensures a stable signal and seamless connection when sending large amounts of print data.
In this guide, we'll cover all available connection methods, including using a USB cable for initial network settings transfer. You'll learn how to avoid common driver-related errors and what to do if the indicators are behaving abnormally. The key point is that the G3400 printer only operates in the 2.4 GHz range and does not see 5 GHz networks.
Preparing equipment and checking router compatibility
Before you start manipulating the buttons on the device body, you need to make sure that the infrastructure is ready. Your wireless router must be enabled and configured correctly. Make sure you know the exact network name (SSID) and password, as this information will be required during the configuration process.
An important aspect is the frequency range. Model Canon Pixma G3400 The router is equipped with a module that supports the 802.11 b/g/n standard. This means that the device will not be able to detect networks that operate exclusively in the 5 GHz band. If your router only broadcasts a high-speed signal, you will need to access its settings and enable a guest network or the main 2.4 GHz channel.
⚠️ Note: If MAC address filtering is enabled on your router, your printer will not be able to connect until you add its unique identifier to the whitelist in your router settings.
It's also worth preparing in advance the computer or laptop to which the MFP will be temporarily connected. For initial setup USB cable This step is essential, as it's through this step that the software will transmit data about your Wi-Fi network to the printer. Without this step, wireless data transfer won't start.
Activating the wireless network setup mode on the printer
The first step in the configuration process is to put the device itself into connection standby mode. In the control panel Canon G3400 There's no full-fledged display, so all actions are performed using button combinations. You need to find the button marked with a smartphone or wireless icon.
Press and hold this button until the power light flashes once, then release it. Immediately after, press the color or black and white copy button. The wireless light should start flashing, indicating that the printer is in setup modeThe device is now ready to search for a host computer.
- 📶 The Wi-Fi indicator blinks slowly - the setup mode has been successfully activated.
- 🔌 The indicator is constantly on - the device is already connected to a network.
- ❌ The indicator does not respond - check the power cable connection.
After activating this mode, you have a limited time (usually a few minutes) to launch the software on your computer. If you don't complete the setup in time, you'll have to repeat the process, putting the printer back into standby mode.
Installing Canon drivers and software
To successfully sync your devices, you must use official software. Download the full package of drivers and utilities from the manufacturer's website, selecting your model and operating system. Using the included discs is not recommended, as the software versions on them may be outdated and lack the latest security protocols.
Run the setup file and follow the on-screen instructions. At some point, the installer will prompt you to select a connection type. Select "Wireless LAN" or "Wi-Fi." The program will automatically search for the printer in the setup mode you activated previously.
in one step.
If the automatic search doesn't yield any results, select the manual setup method. In this case, the program will prompt you to connect Canon G3400 to the computer via a USB cable. This temporary connection is only necessary for transferring network settings. Once the printer receives Wi-Fi data, the cable can be disconnected.
☑️ Pre-installation check
During the installation process, you may be asked to confirm the device connection. Monitor any pop-up windows in your operating system. Antivirus software can sometimes block the installation of network components, so if errors occur, temporarily suspend them.
Configuration via Canon IJ Network Tool
If the standard installation did not go correctly or you want to change the network settings, use a specialized utility IJ Network ToolThis tool is included in the complete driver package and allows you to manage your printer's network settings more flexibly. Launch the program and select your device from the list of available devices.
In the settings menu, select "Wireless LAN" and proceed to changing the settings. The utility will prompt you to select your network from the list of available ones. Enter your Wi-Fi router password. After confirming, software will send a command to the printer and it will try to establish a connection.
| Indicator | State | Meaning |
|---|---|---|
| Wi-Fi (orange) | Blinks slowly | Setup Mode / Network Search |
| Wi-Fi (green) | It's on constantly | Successful connection to the network |
| Wi-Fi (orange) | Flashing quickly | Connection error / No signal |
| Wi-Fi (green) | Flashing | Data is being transferred |
A successful connection is confirmed by a steady green wireless indicator. At this point, the printer has an IP address on your local network and is ready to use. You can check the connection status by printing a network settings report, if available via the hotkey, or by checking the client list on the router.
Direct connection from a mobile device (Canon PRINT Inkjet/SELPHY)
For smartphone and tablet owners, setup can be done even more easily, without a computer. This requires an app. Canon PRINT Inkjet/SELPHY, available in the App Store and Google Play. Make sure your mobile device is connected to the same Wi-Fi network to which you want to connect the printer.
