Turn on your computer and locate the Wi-Fi icon.

One of the features that makes laptop computers desirable is their ability to connect to Wi-Fi networks, thus allowing people who are on the go to be able to check email, browse the web or update social networking status any time they are in a Wi-Fi hot spot.
Fortunately, enabling Wi-Fi on a laptop is simple to do.
Only basic Internet and computer expertise is needed to connect your laptop to a wireless network.

That's it.

unless you have a wireless router in your home; the msg "windows cannot find any wireless networks"

means any network in your area is too far away, or has a signal so weak your laptop is not picking it up as a viable source.

visit . www.filehippo.com and DL a file called Ccleaner. Run this program - it will clean all your internet caches and junk files, then run the registry cleaner. Reboot.
This can keep you from connecting.

Also try moving to different areas in your home and refreshing your wireless search.

if you are worried your wireless card may not be working properly, take it to a place like mcdonalds, or anywhere that has free wi-fi offered. if you still can not pick up a signal there you have narrowed it down to your wireless adapter.

you can also try this little program. Easy Wi-fi radar found here

Connect your router to computer with ethernet cable.
Then access it with following link.
http://192.168.1.1 or
http://1921.168.0.1

type user name as "admin" and password as "admin" or blank or "password"

Then configure your router as WEP.
Then go to wireless and check that wi fi is enabled.

Then go to wi fi security and add WEP key it is your password to connect your wi fi.
Also enable dhcp if you want get ip auto to computers.
configure your wan settings as your internet service provider like dns ip addrses.
Then save settings and restart the router.

Try removing all past connections , go to control panel , delete all your old settings and start new.

Youe broadband router is working ok with the broadband cable.So it is configured with the broadband cable.Now,to work with the wireless internet,you have to configured the wi-fi router to work internet.You can see the wi-fi connection but unless & untill you will configure wi-fi router it must not work or if before it was working with the wi-fi then you can check the wi-fi router setting because it might change by mistake.Surely it will work after configurating wi-fi router.

I think it is saying that the wifi "card" is set so that it is not being configured by windows.

In XP

Control panel > Network connections

Under LAN or High-speed internet you will see an icon labelled wireless network connection. Right click on this and then click properties. You will see three tabs at the top
General - Wireless Networks - Advanced

Click on wireless networks
There should be a tick-box saying Use windows to configure my wireless network settings. I expect that, in your case, the box is unticked which means that the software supplied by the vendor of the wifi card is configuring the settings. I find that it is usually more reliable to let windows do it.

So tick the box and click OK. You may then have to reboot.

Yes you can, you just have to connect to the network wherever you are and provide the password for that location if it has security.

yes if the wireless settings are proper see first it is showing the netwok list in your wireless network select the desire network and put the secret netwok key it will start your wireless network .

but make sure you are not remove the wireless lan adoptor driver .this you can see in the control panel ,sytem ,hardware and device manager in network adoptor.
