Some access points (usually named routers or hubs) have an automatic connection button labeled “WPS,” which is for a Wi-Fi network-protected setup and allows your devices to connect to a network without requiring you to type in your password. If the access point has a WPS connection button, choose ‘WPS Connection Method’ given below for the complete guidelines for connecting by using this method. When there is no WPS connection button on the access point, you can use another optional method that is the ‘Standard Connection Method,’ given below, to connect your Canon PIXMA MG4250 printer to a Wi-Fi network.
Before we begin this process, there are a few conditions that must have to be reached to use the WPS push button method for your Canon PIXMA MG4250 printer:
The access point must have a WPS push button. If your WPS push button isn’t available, you can use the Standard Connection Method section guidelines. Please refer to your device’s user guide for all details.
The network must be using WPA (Wi-Fi Protected Access) or WPA2 security protocols. Most of the WPS-enabled access points use this protocol.
Step 1: Firstly, click on the [Home] button (A) on your printer.
Step 2: Now, use the button (A) to select the [WLAN Setup] icon. Then, click on the left side function button (B).
After that, the (blue) Wi-Fi lamp (C) will light up when a wireless connection is enabled.
The Canon PIXMA MG4250 printer automatically searches for access points supporting the WPS connection button feature.
Step 3: The display on your Canon PIXMA MG4250 printer should be displayed as below:
Click on and hold the [WPS] connection button on the access point for about 5 seconds, then release. Please check its customer guide for precise instructions to start the WPS connection button on the access point.
