I sometimes get annoyed when I scan a duplex over USB. I rarely use WiFi, but I normally scan into ReadIRIS for Mac OS X, I typically use the SD card for transferring information on the Mac and then import the PDF or JPG files into ReadIRIS Pro. Once I figured it out, this scanner works like a charm and it is so versatile. I nearly returned the scanner due to my inability to set up the infrastructure mode connection with my wife. I hope that this information helps anyone who purchased this scanner. If your laptop has a Windows Firewall you might have to set exception so that your laptop can find the scanner or you can input the scanner's direct IP address to help the PC laptop find the scanner. Once the scanner is connected to your home wifi network, every laptop or smartphone device in your home wifi network can control the scanner wirelessly. Connect to your home via 2.4G but not 5G and you will need to input the password or security key of your home wifi network. Follow the prompts of the StepbyStep Installation Wizard to connect the scanner to your home or office WiFi network. Please click the button 'Wireless Setup Wizard' and then start the widget. You should see the Wireless Setup Wizard on the left side. Select Wireless in the area called Network. Once you have logged in, you can change the password, or leave it as is.

You need to login either using the default password initpass or the first password printed on the bottom of the scanner.

You can set the machine setting in another app/software called Brother Utilities instead of using iPrint & Scan.

You can install Brother's iPrint&Scan on your Windows Mac or iOS device and connect the scanner via the wireless direct through Brother's WiFi network using the Direct Wifi network. Remove the scanner from the USB connection. Connect the scanner to the included laptop or desktop USB cable to charge it until the battery signal turns from orange to stable green. You cannot blame them because it is complicated and it's unfortunate that Brother makes such a great product but doesn't give a clear instruction. Most people were not able to setup the Infrastructure mode of the wife connection. It connects to your WiFi router in infrastructure mode, and allows all devices in the same wifi network to control it if you know how to set it up. This scanner is not only an automatic WiFi network connection.
