The issue can be due to a lot of reasons. To begin, try connecting another device in your home to your wireless network to make sure the wireless network is working. If not, you may need to restart your router. Make sure the printer is 5 feet apart from the router and that it is not placed near a microwave, cordless phone or large metal objects. Additionally, you may have to input the name of your network (SSID) manually if it doesn’t appear, or check to make sure the WEP keys are entered correctly.
