Which operating system ???...
There are a variety of ways to connect to the Internet or a
home/business network using your Hewlett-Packard (HP) desktop computer---via a
modem, Ethernet cable and even wirelessly.
A wireless connection works by sending a signal from your
modem or router to your HP desktop's built-in wireless radio.
The radio receives and processes the signal so you can
access the Internet or a home or business network.
In order for the signal to be received by your HP desktop,
you must enable the wireless radio within the computer's configuration.
Click "Start," "Control Panel."
Double-click on the "HP Wireless Assistant" icon.
The HP Wireless Assistant dialog box will open.
Click the "Turn On" button
next to the words "Wireless LAN."
Click "Close" to activate the wireless radio.
