Now a days most of persone have smart phone that have enable 3G and GPRS,for that purpose use the internet on mobile phone using laptop/pc net connection there is best option,so today i Give tutorial about How to Turn your Windows 7 PC into a Wi-fi Hotspot.
If you are not using Windows 7 yet, you can accomplish the same thing in Windows Vista, XP or even Mac OS X. The Windows 7 method is almost identical to Windows Vista, but XP requires a few more steps.
Before we begin, make sure that you have got a laptop or desktop with a wireless card (Wi-fi card). Your laptop or desktop must be connected to a wired network and the wireless card must be free so that it can be used as a Wi-fi hotspot. Please note that this won’t work on some networks that use group policies to enforce TPS report and prevent you from having any fun at all.
Let’s begin.
Go to “Network and Sharing Center” through the Control Panel or quickly type “Network” in the Start menu’s search bar and click on “Network and Sharing Center”. Once you are there click on “Set up a new connection or network”. You’ll be prompted with a wizard that allows you to connect to VPNs, dial-up, or create a new ad hoc wireless network. If you see this wizard, you are on the right path. Click on Next.
Step 3 - Enter Details
On the new window, provide a name to the network, set the security type and the security key which will act as password while other Wi-fi devices try to connect to this network. Please remember that WEP is much easy to crack compared to WPA2. So, it will be better if you select “WPA-2 Personal” for Security type. Also, provide a strong password to avoid misuse of your wireless ad hoc network. Tick mark the “Save this network” and click on OK and finally click on Close.
At this point your ad hoc network should be running and ready to start connecting your devices, but you’ll have to hold off for just a minute.
Step 4 - Network List
You’ll notice that the ad hoc network that you created gets added to the quick-select wireless network list—when you disconnect from your ad hoc network, it’s the same as stopping it. Connecting to the network is the same as starting it back; this way you can quickly switch back and forth between connections with just a few clicks.
The last step is enabling connection sharing through your regular network card, which will allow anybody connected to your ad hoc wireless to use your internet connection. To do so, go to the “Network and Sharing Center”, click the “Change adapter settings” link on the left, and then find your network connection (wired one) in the list—it’s very important that you only enable internet connection sharing on the adapter that is actually connected to the internet. In this case, my wired internet access goes through my Local Area Connection, so I’ve enabled it there.
Tick mark on both the options provided in the Sharing tab. Also, select you wireless connection card in “Home networking connection”. Don’t worry if there isn’t any option like “Home networking connection”. Click on OK.
At this point, you should be able to connect any Wi-fi enabled device to your new ad hoc network and access the internet, or even share files directly with your laptop.
