Canon MG3600 Does Not Connect After Replacing the Router or Changing the Wi-Fi Password

Last Updated on 22.07.2026 by DriverNew

After replacing the router or changing the wireless network name or password, Canon PIXMA MG3600 series may stop printing and scanning over Wi-Fi. In Windows, the device often remains in the list but is shown as unavailable or has an “Offline” status.

The reason is that the multifunction printer continues to store the settings of the previous network. The new network name, password, and security method are not transferred to it automatically.

This guide applies to the following models:

Canon PIXMA MG3610, MG3620, MG3640, MG3640S, MG3650, MG3650S, MG3660, MG3670, and MG3680.

All the devices listed above belong to Canon PIXMA MG3600 series. Model names vary depending on the country where the device is sold.

When Wi-Fi must be configured again

New network settings must be transferred to the multifunction printer if any of the following changes have occurred:

• a new router was installed;
• the Wi-Fi network name was changed;
• the password was changed;
• the network security method was changed;
• the 2.4 GHz band was disabled;
• the multifunction printer was moved to another location or is connecting to another network;
• the router settings were reset;
• the printer continues connecting to an old range extender or access point.

Simply restarting the multifunction printer does not replace configuring it again. The device will continue searching for the network using the previously saved name and password.

First, check the new router

Before changing the multifunction printer settings, make sure that the wireless network is configured correctly.

1. Turn on the router.
2. Wait until the device has fully started.
3. Make sure that the computer can access the internet through the new router.
4. Check that the 2.4 GHz band is enabled.
5. Write down the exact Wi-Fi network name.
6. Write down the password for this network.
7. Make sure that the main network, not a guest network, is being used.

During setup, place the multifunction printer near the router. After the connection is established successfully, you can return it to its permanent location.

The easiest option: keep the previous network name and password

If you know the old network name and password, you can configure the new router with the same settings. In this case, MG3600 series may sometimes connect automatically without reinstalling the driver.

On the new router, specify:

• the same 2.4 GHz network name;
• the same password;
• a compatible security method, such as WPA2-PSK;
• AES encryption.

After saving the settings:

1. Restart the router.
2. Wait for the Wi-Fi network to appear.
3. Turn off the multifunction printer.
4. Wait approximately 10 seconds.
5. Turn on the multifunction printer.
6. Wait several minutes.
7. Check whether the Wi-Fi lamp lights up.
8. Try printing a document.

Method 1. Transfer the new settings using the Canon installer

This is the main method for Windows 11 and Windows 10. If the installer cannot find the multifunction printer on the network, a USB cable is used temporarily to transfer the new Wi-Fi name and password.

What you will need

• a computer connected to the new router;
• the password for the 2.4 GHz network;
• the official Canon MG3600 series MP Drivers package;
• a printer USB cable.

WPA3 security

If the router is configured for WPA3 only, temporarily change the mode to WPA2-PSK or a compatible mixed mode that allows WPA2 devices to connect.

Guest network

Do not connect the multifunction printer to a guest network if device isolation is enabled. On such a network, the computer may have internet access but may be unable to detect the printer.

MAC address filtering

If the router allows connections only from registered devices, add the multifunction printer’s MAC address. It is shown on the network settings printout.

DHCP

Make sure that the DHCP server is enabled. It assigns a new IP address to the multifunction printer.

Client isolation

Check for settings with the following or similar names:

• AP Isolation;
• Client Isolation;
• Wireless Isolation;
• wireless device isolation;
• block access to the local network.

For standard printing and scanning between the computer and multifunction printer, this isolation must be disabled.

8. Turn on the multifunction printer again.

After the reset, run the MP Drivers package and perform the wireless setup again.

If the installer does not detect the multifunction printer via USB

During temporary network setup, the installer must detect the multifunction printer through the cable.

If the “Connect Cable” window does not close automatically:

1. Make sure that the multifunction printer is turned on.
2. Check whether the error lamp is lit.
3. Insert the cable firmly into the port on the back of the multifunction printer.
4. Connect the cable directly to the computer.
5. Do not use a USB hub or extension cable.
6. Try another USB port.
