***The Dell E193FPc is a monitor, not a PC.*** To connect to Wi-Fi on a Dell PC, you'll need a desktop or laptop computer with built-in Wi-Fi capabilities or a Wi-Fi adapter. Make sure your PC has a Wi-Fi card or adapter installed and check your network settings to connect to a Wi-Fi network. If you need more specific help, please provide the model of your Dell PC and I can guide you further.
