Check the following:
1. Whether you have disabled the Wireless Lan Card from the OS
2. See if there is a button on your notebook that can disable the Wireless Lan Card, like Sony notebook
3. See if you have typed the IP manually in the Wireless Lan Card. If it is, restore it to obtain IP automatically
4. See if you have disabled the DHCP from the wireless router
5. In command prompt (cmd.exe), type
ipconfig /release
ipconfig /renew
ipconfig /all
Then see if there is an IP from your wireless router. Normally, the IP is like 192.168.1.x see you didn't change the DHCP IP range from the router
Hope these could help you!!!
