Wireless network card driver

Hello,


i have recently bought compaq 610 notebook.. when i started it there was wireless connection working but i formatted the window to make drives partition.. but after that i m unable to install wireless network card driver.. i installed one time but it has installed realtek RTL 8191SE 802.11b/g/n WiFi Adapter.. it is showing me wireless connections available but it cant connect with them.. and when i checked the specifications of compaq 610 notebook.. there is shows wireless network card is made by Intel.. i tried to install intel's card driver from many places even from intel website but unable to install it.. notebook is not installing any other driver..
