How to connect a Canon PIXMA MG3540 printer to Wi-Fi: step-by-step instructions with photos

Printer Canon PIXMA MG3540 — a popular model among home users due to its compact size and support for wireless printing. However, connecting to Wi-Fi networks often causes difficulties: the device doesn't find the network, asks for the password again, or refuses to connect altogether. In this article, we'll look into all working connection methods (including WPS, the standard method and the alternative via USB), as well as typical errors and their solutions.

If you've already tried setting up a connection, but the printer still doesn't appear in the list of available devices, don't rush to reset the settings. In 80% of cases, the problem lies in incorrect router parameters or missed installation steps. We'll walk you through each step in detail so you can print your first document without any hassle.

⚠️ Important: Before you start, make sure your router supports the standard 802.11b/g/n on frequency 2.4 GHz. MG3540 does not work with networks 5 GHz or new protocols like Wi-Fi 6If your router is dual-band, temporarily disable the network. 5 GHz in its settings.

1. Preparing the printer and router for connection

Before setting up wireless connection, perform basic checks. This will save time and eliminate common errors:

• 📌 Make sure the printer Canon MG3540 Turned on and within range of the router (no more than 5-7 meters). Walls and metal objects can block the signal.
• 🔌 Connect the printer to the power supply without using extension cords — power surges can disrupt the Wi-Fi module settings.
• 📡 Check that the wireless network indicator on your router (usually marked with an antenna icon) is lit. If it's blinking or not active, reboot the router.
• 🔒 Check the name of your Wi-Fi network (SSID) and password. If you forgot it, look at the sticker on the back of the router or in the web interface (usually at 192.168.0.1 or 192.168.1.1).

If your router uses hidden SSID (the network is not broadcast), temporarily disable this feature in the settings. MG3540 doesn't support connecting to hidden networks manually. Also, check that your router MAC address filter disabled - it can block a new device.

⚠️ Attention: if you use guest network On your router, the printer may not connect due to communication restrictions. Try using your primary network.

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

Technology WPS (Wi-Fi Protected Setup) allows you to connect your printer to your router without entering a password—just press a button on the router. This method works if your router supports WPS (usually marked with a lock icon or the word WPS).

Step-by-step instructions:

1. On the printer MG3540 press and hold the button Wi-Fi (antenna icon) until the indicator starts flashing in blue (about 3 seconds).
2. For 2 minutes press the button WPS on the router. The indicator on the printer should light up. green - this means that the connection is established.
3. Wait for the printer to print connection report (Network information sheet). If printing does not start, check that there is paper in the tray.

If the indicator light on the printer continues to flash blue or turns on orange, this indicates a connection error. Try repeating the process, making sure that:

• 🕒 The time between pressing buttons on the printer and router does not exceed 2 minutes.
• 🔄 The router is not overloaded (temporarily disconnect other devices from Wi-Fi).
• 🔌 The printer and router are connected to the same power grid (sometimes WPS requires this).

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

If your router does not support WPS or the button is missing, use standard connection method (described in the next section). Alternatively, you can enable WPS through the router's web interface: find the section Wi-Fi Protected Setup or Fast connection and activate the function for 2-5 minutes, then repeat the steps on the printer.

3. Method 2: Standard connection via the printer menu

If WPS doesn't work or your router doesn't support it, use manual entry of network parametersTo do this:

1. Click the button Wi-Fi on the printer and hold it until the indicator light starts flashing blue.
2. Click the button Black (or Color(depending on the firmware) once. The indicator should flash green and orange - this means that the printer is ready for setup.
3. Press and hold the button Cancel/Stop (red circle) until the indicator starts flashing blue and green alternately. This activates the setup mode.

The printer will now begin searching for available networks. When the indicator starts flashing green, follow these steps:

4. Click the button Wi-Fi once - the printer will print a list of found networks.
5. Find your network in the list (SSID) and write down its number (for example, #1).
6. Click the button Black as many times as your network number (for example, 1 time for #1).
7. To enter a password, use the printer buttons:
   • 🔢 Numbers: Press the button Black to select a number, Color — to move to the next one.
   • 🔤 Letters: Use multiple taps (e.g. 2 times for B, 3 times for C).
   • 📌 To enter uppercase characters, press Wi-Fi before choosing a letter.

After entering the password, press and hold Blackuntil the indicator starts flashing green - this means that the printer is connecting.

If the printer can't connect, it will print an error page. For a breakdown of the error codes, see FAQ at the end of the article.

4. Method 3: Connecting via USB (Alternative Method)

If the printer stubbornly does not see the network or you cannot enter the password via the buttons, use USB cable for initial setup. This method requires a computer with the software installed. Canon, but it is guaranteed to work even if there are problems with Wi-Fi.

Step-by-step instructions:

1. Connect the printer to the computer via USB cable (included). Make sure the printer is turned on.
2. Download and install drivers and utilities With official Canon website (select model PIXMA MG3540).
3. Run the program Canon IJ Network Tool (included in the software package).
4. In the program window, select your printer and click Setting up the connection.
5. Follow the wizard's instructions by selecting your Wi-Fi network and entering the password using your computer's keyboard.

After successful setup, disable USB cable — the printer must remain connected to Wi-Fi. Check this by printing test sheet via the printer menu (Settings → Print Test).

⚠️ Attention: If the printer loses its Wi-Fi connection after disconnecting the USB port, check the power saving settings on your router. Some models turn off "sleeping" devices—find this option in the router's web interface. AP Isolation or Energy Saving and turn it off.

5. Configuring the router for stable printer operation

Even if the printer is connected, problems may arise over time communication problems: Print interruptions, long response times, or an inability to find the device on the network. This is most often due to router settings. Recommended settings for MG3540:

Parameter	Recommended value	Where to change
Wireless network mode	802.11b/g/n mixed	Wi-Fi Settings → Network Mode
Wi-Fi channel	1, 6 or 11 (least loaded)	Wi-Fi Settings → Channel
Channel width	20 MHz	Wi-Fi Settings → Channel Width
Security	WPA2-PSK (AES)	Security Settings → Encryption Type
DHCP	Included	LAN Settings → DHCP Server

If your router supports Qos (Quality of Service), add your printer to the priority list. This will help avoid delays when printing large documents.

⚠️ Attention: if you use Mesh system (For example, Google Nest Wi-Fi or TP-Link Deco), the printer may become "lost" when switching between nodes. In this case, assign it to one of the nodes in the mesh network settings.
