Setting up a wireless connection for a Pixma series multifunctional device often turns into a test of the user's patience. Model Canon MG3240Despite its popularity and availability, the printer requires strict adherence to the correct sequence of steps to successfully sync with the router. Mistakes in selecting the method or ignoring the correct order of device connections can result in the printer remaining "blind" to your home network.
In this guide, we'll cover all current setup methods, from using an automated wizard to manually assigning IP addresses. You'll learn how to properly prepare your equipment, which drivers to download, and what to do if the Wi-Fi indicator keeps blinking and won't stay lit.
Before moving on to the software part, make sure that your device is physically ready for work. Wireless setup is impossible without basic hardware preparation and checking the compatibility of your local network components.
Equipment preparation and compatibility testing
The first step is to check the device's packaging and condition. Make sure the printer has cartridges and paper installed, as many Canon models block network functions if consumables are missing or if the covers are open. It's also critical that the router operates in the 2.4 GHz band, as older Wi-Fi modules in MFPs MG3240 may not support 5 GHz frequency.
Next, you need to determine the connection type of your computer or laptop. If you plan to set up the network from a device that is connected via Wi-Fi, the process will be automatic. However, if your PC is connected to the router via an Ethernet cable, you will need to temporarily switch to a wireless connection or use the WPS method to simplify the process.
⚠️ Important: Make sure Client Isolation is disabled on your router. If this option is enabled, the computer and printer will see the router but will not be able to see each other on the network, making printing impossible.
To successfully integrate the device into your office or home infrastructure, you'll need the following information, which can be found on the router's sticker or in your contract with your provider:
- 📡 SSID — the exact name of your wireless network (case sensitive).
- 🔑 Security key — Wi-Fi password (usually WPA2-PSK).
- 🌐 Encryption type — most often AES or TKIP.
- 💻 Gateway IP address — router address (for example, 192.168.0.1 or 192.168.1.1).
Write this information down or keep it handy. In some cases, automatic network detection may not work, and you'll have to enter the parameters manually using specialized software.
WPS method: Quick setup without entering a password
The easiest way to establish communication between Canon MG3240 and the router—use WPS (Wi-Fi Protected Setup). This method allows devices to exchange encryption keys automatically, eliminating the need to manually enter a long and complex password. First, make sure your router has a physical WPS button or the corresponding function is enabled in the web interface.
On the MFP control panel, locate the button with an antenna or smartphone icon. Press and hold it for a few seconds until the power light starts flashing. This will put the printer into connection standby mode. Immediately afterward, press the WPS button on your router.
The data exchange process may take up to two minutes. During this time, the wireless network indicator on the printer will blink. Once the connection is established, the indicator will turn solid blue or green (depending on the model), indicating success.
☑️ Checklist for a successful WPS connection
If automatic connection fails and the indicator stops flashing, proceed to more detailed setup methods. Sometimes failure is caused by excessive distance between the devices or temporary interference in the air.

Sequence of actions in the installation wizard:1. Run setup.exe
2. Select region and model
3. License Agreement
4. Select "Wireless LAN connection"
5. Connect USB cable on demand
6. Enter the Wi-Fi password
7. Disconnecting the cable
This method is especially good because it immediately installs not only print drivers, but also utilities for scanning over the network, which eliminates the need for additional configuration in the future.
Configuration via Canon IJ Network Tool
For advanced users or in cases where the standard installer does not work correctly, there is a specialized utility IJ Network ToolIt's included in the full driver package, but can be run separately. This tool allows you to manage the printer's network settings, view the status, and change the TCP/IP configuration.
Run the program as administrator. You'll see a list of printers in the main window. If the device is connected via USB, select it. Go to the "Settings" menu and select "Wireless LAN." Here you can reconfigure the network without reinstalling the drivers.
The utility allows you to manually enter a static IP address, which is useful on corporate networks or if the router frequently changes device addresses. You can also check the signal strength and the exact network name you're connected to. Canon MG3240.
| Parameter | Description | Recommended value |
|---|---|---|
| SSID | Network name | Auto or exact name |
| Channel | Broadcast channel | 1, 6 or 11 (for 2.4 GHz) |
