I own a Dell Inspiron 14R Model No. N4010, which is 3 years old and no more in the warranty period.

There is an issue with the Wi-Fi and LAN of the laptop. The drivers are not being installed on the Laptop as it is detectong an error from hardware. I showed my lappy to a Technician, for which he tried to replace the wi-fi chip but the issue was not resolved then too. He is telling that there is a problem somewhere in the motherboard due to which the hardwares are not being detected. The net is working perfect using separate USB dongle and there is no problem iin the other working of the laptop. What can be the problem and what should I do?
