Hi Arun,

There are a number of reasons why you might not be able to see your wireless network on the list of available networks from the system menu.

• If no networks are shown in the list, your wireless hardware could be turned off, or it may not be working properly. Make sure it is turned on.
• You could be out of range of the network. Try moving closer to the wireless base station/router and see if the network appears in the list after a while.
• The list of wireless networks takes time to update. If you have just turned on your computer or moved to a different location, wait for a minute or so and then check if the network has appeared in the list.
• The network could be hidden. You need to connect in a different way if it is a hidden network.

Method 1: Enable the WiFi service
The problem happens most likely because your Windows disables the WiFi service. You can’t connect to the WiFi if your Windows disables it. So you can try these steps to enable WiFi service. There are two places you can check.

Way 1: Enable the WiFi service with the WiFi switch
Note: First of all, make sure you are within the WiFi network range while you are following the steps below.
Some laptops, such as HP, Lenovo, Dell, have a switch or a key on your keyboard to turn on/off WiFi (like Fn+F5). Check the switch or keys and turn your WiFi service on.


Way 2: Check your network settings
If you don’t have the WiFi switch on your laptop or computer, you can check it in your system.
1) Right click the Internet icon, and click Open Network and Sharing Center.

2) Click Change adapter settings.

3) Right click WiFi, and click Enable. Note: if it has enabled, you will see Disable when right click on WiFi (also referred to Wireless Network Connection in different computers).

4) Restart your Windows and reconnect to your WiFi again.

Method 2: Turn on WLAN AutoConfig servic
1) On your keyboard, press Windows logo key + R at the same time to invoke the Run box, and type services.msc, then press Enter.

2) Right click Wlan AutoConfig (if you are using Windows XP, right click Wireless Configuration), and click Properties.

3) Select Automatic in Startup type, then click Apply, and click OK

4) Restart your PC and reconnect to your WiFi network to see if your WiFi shows up.

Method 3: Restart your modem and WiFi router
If the problem occurs to your own WiFi network at home, you can also check the WiFi itself to see if it’s your WiFi issue, including the router issue, SSID broadcast and device interference mentioned below.
This problem can be probably caused by the Internet Service Provider (ISP) issue. Restarting your modem and wireless router can help you reconnect to your ISP. Note: anyone who is connecting to the network will be disconnected temporarily while you are doing this.
1) Unplug your wireless router and modem from power source (remove the battery if your modem has a battery backup).
2) Wait for at least 30 seconds.
3) Plug your wireless router and modem back into power source again (put the battery back to the modem).
4) On your PC, reconnect to your WiFi network, then see if it shows up.

I hope this helps.

Lokesh
