my wi fi orange light is blinking on my lexmark x4650 printer


The blinking WiFi light on your printer indicates either your printer is trying to communicate with your wireless network or your printer is not connected at all. For a quick fix, try to disconnect your printer from the power outlet. Power cycle your router and reboot your computer. Then, power on your router first, then your printer and lastly your computer. Check the WiFi light on your printer. If it goes to a solid green, that means you are connected back in your network. If not, you may reset your printer's wireless network adapter to its default settings. From the printer operator panel, press the Setup button > Network Setup > Reset Network Adapter to Default. The WiFi light on your printer will momentarily turn off then back on solid orange. Then try to run the Lexmark Wireless Setup Utility on your computer to reconfigure your printer to connect to your wireless network.
I hope this helps.
