i am unable to use wi fi because my dhcp is not enabled can anyone tell me the solution of enabling the dhcp i will be very thankful to u if any plzz help me out

You'll have to explain what you mean. Is DHCP turned off in Windows, or is it turned off on your router? Is your router even WiFi capable? DHCP is on by default in Windows. To check this go to Start Orb->Control Panel->Network and Sharing Center->Change Adapter Settings. Right-click on your Wireless adapter and select Properties. Click on Internet Protocol Version 4 (TCP/IPv4) and select Properties again. Make sure Obtain an IP address automatically is selected.
