• Verify that your router or access point is operating correctly by connecting to it from your computer or another device. • You may need to disable the firewall and any anti-virus software on your wireless router or access point. • Check to see if access restrictions, such as MAC address filtering, are set on the router or access point. If access restrictions are set, add your scanner's MAC address to your router's address list. To obtain your scanner's MAC address, check the label on the back or bottom of your scanner. Then follow the instructions in your router or access point documentation to add the address to the list. • If your router or access point does not broadcast its network name (SSID), follow the instructions that came with your scanner to enter your wireless network name manually. • If your router or access point has security enabled, determine the kind of security it is using and any required password or passphrase for connection. Then make sure to enter the exact WEP key or WPA passphrase correctly. • Check if your computer is restricting the available wireless channels. If so, verify that your wireless access point is using one of the usable channels and change to a usable channel, if necessary. • If you connected your scanner to a Windows computer using a direct Wi-Fi connection and it automatically selected Access Point Mode, you may have trouble accessing a low-priority Internet connection. Check the network connection or adapter settings in the Windows Control Panel and set the Internet metric setting to 100 for your version of the Internet Protocol. • The scanner may not be able to communicate with a computer with multiple network interfaces. Disable all network interfaces except for the interface connected to the scanner. • Enable the DHCP function on the access point or router. • Check that the scanner's IP address is set correctly.
