How to Set Up Wi-Fi on a Canon PIXMA G3400 Printer: 3 Proven Methods + Troubleshooting

Connecting a printer Canon PIXMA G3400 Connecting to a wireless network is a challenge faced by both novice and experienced users. Despite its apparent simplicity, the process can be complicated by mismatched firmware versions, router features, or simply inattention to detail. This article will help you avoid common mistakes and set up Wi-Fi on the printer as quickly as possible, regardless of whether you use WPS, device control panel or mobile app Canon PRINT.

Model G3400 It belongs to a series of inkjet MFPs with wireless printing support, but its interface differs from its laser counterparts. For example, it doesn't have a touchscreen—only buttons and LED indicators, which requires a special approach to setup. We'll cover all the current connection methods, including manual password entry, and we will also give recommendations on how to resolve common problems, such as the error E08 or failure to detect the network.

1. Preparing the printer and network for Wi-Fi setup

Before you start connecting, make sure that your Canon G3400 and the router are ready for the procedure. Skipping this step often leads to failures, such as the printer not seeing the network or constantly losing connection.

First, check physical condition of devices:

• 🔌 The printer must be plugged into a power outlet and in standby mode (the power indicator is green).
• 📶 The router must be turned on and distributing Wi-Fi (the wireless network indicator is active).
• 📱 You must have a smartphone/tablet with the app installed on hand Canon PRINT or a computer with printer drivers.

Secondly, pay attention to router settings:

• 🔒 The network must use WPA2-PSK (or WPA3) - printer G3400 does not support legacy protocols like WEP.
• 📡 Wi-Fi frequency: 2.4 GHz (5 GHz is not supported!). If you have a dual-band router, temporarily disable 5 GHz or create a separate network for 2.4 GHz.
• 🔄 Disable the "Hidden Network" (Hidden SSID) feature - the printer will not be able to connect to a network that does not broadcast its name.

Finally, update your printer's firmware, if possible. Outdated firmware can cause conflicts with modern routers. You can check the latest version using the utility. Canon IJ Network Tool (download from official website).

2. Method 1: Connecting via WPS (the fastest method)

Technology Wi-Fi Protected Setup (WPS) Allows you to connect your printer to the network without entering a password—just press a button on the router. This method only works if your router supports WPS (usually there's a button labeled WPS or marked with a 🔄 icon).

Step-by-step instructions:

1. Make sure your router is turned on and distributing Wi-Fi.
2. On the printer Canon G3400 press and hold the button Wi-Fi (📶) for 3 seconds until the indicator starts flashing blue.
3. For 2 minutes press the button WPS on the router. The printer's indicator light should turn green, indicating a connection has been established.
4. Wait for the printer to print a connection report (a sheet with the network name and IP address).

If the indicator continues to flash or remains orange, this indicates an error. Possible causes:

• ⏱️ Timed out (please try again soon).
• 🔌 WPS is disabled in the router settings (enable it in the router's web interface).
• 🔒 The router is using an incompatible security protocol (switch to WPA2-PSK).

What should I do if my router doesn't have a WPS button?

Some models (such as Apple or ISP routers) don't have a physical WPS button. In this case, use the manual connection method via the printer control panel or the WPS PIN code, which can be found in the router's web interface.

3. Method 2: Manual Wi-Fi setup via the printer control panel

If WPS is unavailable or doesn't work, set up the connection manually. This will require you to enter the network name (SSID) and a password using the printer buttons. The process is a bit longer, but more secure.
