My built in wifi HP Wireless Assistant is not available. Ineed to install it again. It is a wireless network adoptor to connect internet via wifi

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.

SETTING UP A WIRELESS PRINTER WITHOUT A WIRELESS ROUTER - WINDOWS 7
Install Virtual Router first "Turn any Windows 7 or Windows 2008 R2 Computer into a Wifi Hot Spot."
EditByBSEditor: Virtual Router turns any Windows 7 or Windows 2008 R2 Computer into a Wifi Hot SPOT using Windows 7's Wireless Hosted Network (Virtual Wifi) technology.
The Wireless Network Create/shared with Virtual Router uses WPA2 Encryption, and there is not way to turn off that encryption. This is actually a feature of the Wireless Hosted Network API's built into Windows 7 and 2008 R2 to ensure the best security possible.
You can give your "virtual" wireless network any name you want, and also set the password to anything. Just make sure the password is at least 8 characters. http://www.brothersoft.com/virtual-router-327895.html Then install Connectify-Me Connectify is an easy to use software router for Windows 7 computers. After downloading and installing the lightweight application, Connectify utilizes your computers' built in Wi-Fi card to wirelessly share any available Internet connection: a cable modem, a cellular card, or even another Wi-Fi network. Other Wi-Fi enabled devices including laptops, smart phones, music players, and gaming systems can see and join your Connectify hotspot just like any other Wi-Fi access point and are kept safe and secure by password-protected WPA2 Encryption. http://www.connectify.me/ Then reboot computer

Hello Blac,

All the laptops available in market have built in wireless 802.11 b/g/n or 802.11 b/g/n Bluetooth® wireless networking. It means that you can access the internet via Wi-Fi or through Wi-Fi hotspots. In wireless connectivity you do not require the wired connection to access the internet. In home you can connect the laptop via wireless connection using the home networking router available in market. The advantage of wireless connection is that you can use the internet in your home anywhere with in 100 meters of range with proper wireless signals. You will require to get the internet connection from the ISP(Internet Service Provider).

1. Purchase a wireless router that fits your needs and price range.

2. Follow the router's manual to set up the router and its Internet connection, which will probably require connecting a wired client to the router. Once the wireless router is set up, the wired connection is no longer necessary. However, it's best to leave the wired client connected if it's a separate computer from that on which you're going to set up WiFi. If something goes wrong, you can access the administration interface again.

3. Gather information from the setup process. In order to set up the wireless client, you will need to know the service set identifier (SSID), the Wireless Encryption Protocol (WEP) key and the channel and mode.

4. Boot up the laptop and plug in the WiFi card. This will not be necessary if your laptop has an integrated WiFi card.

5. Install any drivers needed to use the WiFi card. Insert the disc that came with the WiFi card and follow the on-screen installation process. Most discs will trigger a new hardware wizard that makes installation extremely simple.

6. Double-click on the "WiFi Connection" icon. It can be found in the system tray at the bottom of the laptop screen.

7. Click on "Properties."

8. Select the "Wireless Networks" tab.

9. Use the "Add" button at the bottom of the dialog if your WiFi network isn't in the "Available Networks" section.

10. Click on "Configure" when you see your network's SSID in the "Available Networks."

11. Enter your network's SSID and WEP key.

12. Click on "Start," then choose "Connect To" and "Wireless Network Connection." Your computer should now be able to access the WiFi network. If the WiFi network is connected to the Internet, it should also be able to connect to the Internet.

Thanks.
Have great day.

I used to have internet wireless connection problems and finally realized that F761usa front wirless swich was changed frequently, even I believe I never touch there.

Is your wireless network working fine? If yes, it is better to close HP Wireless assistant program as windows has inbuilt program to detect the WIFI connections. You can type "msconfig", go to startup and close the required process. It should stop.

Windows WiFi Fix,

Windows Zero Wireless Configuration is one of the best programs to run a WiFi in Windows XP or Vista. Most of the other software packages that come with the different adapters have been poor at best in keeping a connection through Windows. Here is the best guide to get you back up and connected.

Windows XP:

Click Start
Right click on My Computer
When a window pops up click on properties
Click on the Hardware tab
Click Device Manager
Click the [+] next to Network Adapters
Find your wireless card and right click on it.
Click Disable
Windows may warn you that disabling the device may make it stop functioning.
Continue disabling the device.
Wait 30 seconds or so.
Right click on your wireless again and click Enable.
Exit the device manager.
Reconnect to your router.
You should now be able to connect to the internet.

Windows Vista:

Click Start Logo
Right Click Computer
Click Device Manager
Windows will ask you about opening Device Manager Click Continue
Click the [+] next to Network Adapters
Find your wireless card and right click on it.
Click Disable
Windows may warn you that disabling the device may make it stop functioning.
Continue disabling the device.
Wait 30 seconds or so.
Right click on your wireless again and click Enable.
Exit the device manager.
Reconnect to your router.
You should now be able to connect to the internet.

Hi!

Check with your laptop's manual or specification sheet if it came with a built in wireless adapter. If it does, then you do not need to use a wireless adapter. All you have to do is to configure the wireless utility of your laptop to connect to your preferred wireless network.

You can also check Device Manager to check if there is a built in wireless adapter. Assuming you are using Windows XP - Go to Control Panel > System > Hardware > Device Manager. Look for Network Adapters. Check if there is anything under Network Adapters that says "wireless" or 802.11A/B or G. If there is, then again you do not need to install a wireless adapter.

Once you verified that there is a built in wireless adapter, just configure the wireless adapter utility to connect wirelessly to you preferred network.

Good luck and have a nice day!
