Printer cannot be used after replacing the wireless router or changing its settings
Solution
If you replace your wireless router or change its security settings (for example, changing from WEP to WPA2), the wireless network connection between the printer and the router must be set up again.
The correct connection method to use depends on the type of wireless router.
Refer to [ How to connect the printer and router via wireless LAN ] and connect the printer to the wireless router.
