If your printer suddenly got disconnected from your network, try to move it away from any interference and closer to your router.

If the WiFi light is on solid orange then it's totally disconnected from your network. You'll need to reconnect your printer back to your network. Just run the Wireless Configuartion Utility.

To access that, on your computer, click on Start > All Programs > Lexmark 3600-4600 Series > Tools > Wireless Configuration Utility.

When the orange light is solid it means the cartridge is low and you can still print. But when the orange light is flashing it means the cartridge is empty and the printer stops printing. To continue printing you will need to replace the yellow toner cartridge. The part numbers are Q3972 regular yield or Q3962A high yield.

Try removing the jetdirect and power cycle the printer.
