How do i enable the wireless network on a HP PC desktop

Try a monitor reset. Power off the PC and monitor. Unplug the monitor and hold down the monitor's power button for 30-60 seconds. Plug the monitor back in and then power up the system.

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.

Wireless networking center

the most likely issue is the computer's graphics card. to avoid extra problems, try replacing it with the same model graphics card.

Loosing wireless network in HP is very common. They often loose network when they are overheated. The point that is to be noted when it looses the wireless network is, it automatically disables the wireless network adapter. When you right click and select enable, it wont work. You need to restart your system in order to enable it. I myself faced same problem.
But when i updated the WiFi driver from HP support and driver site, the problem disappeared.

hope this will help....cheers:)

Try going to Network and Sharing Center - Manage Network Connections. Click on the connection and enable it.
Also try Network and Sharing Center - Manage Wireless Connections, and moving the wireless connection you'd like to use and move it to the top of the list. Select any operations that will enable or connect to the network.

Thanks

after looking over the spacifics of the model you posted, I'm not certain that you are correct in assuming this monitor is meant to be viewed virtically. The issue is the monitor's resolution. Typicaly, your monitor's resolution dictates it's orientation. for your model:
Recommended resolution (H x V) 1680 x 1050 @ 60 Hz
that means your monitor is not meant to be virtical. However...
If you indeed wish to tilt your monitor on it's side, depending on your graphics card, you may be able to use proprietary software to " rotate " the display.

(nVidia has settings such as these for some of thier graphics cards. )

check you wireless router settings if the wireless is enable on the router then , if this is done disable the firewall on your wireless laptop and if you cannot still connect to the wireless uninstalled and reinstalled your wireless driver software.

go to the HP website and there in the support area, you can download the latest driver for your PC. Also, go to the connection properties to Enable the wireless (via the control pannel)

If you need to find the Wireless Utility to scan for available networks, it should be in Start > Programs under HP Wireless

If you need to turn your wireless adapter on:

First, check to see if there is a button on the keyboard that looks like an antenna. It usually hasF a blue light on if it is enabled. If not, press it. If you are using Windows XP Click Start, then select Control Panel.
Click Network and Internet Connections. The Network and Internet Connections
Click window opens. Network Connections. The Network Connections window opens.
Right-click Wireless Network Connection.
Select Enable to turn on wireless Ethernet or Disable to turn off wireless Ethernet.
