Hi:

There is no information online regarding what model wifi adapter your notebook comes with.

Go to the device manager.

If the wifi adapter needs a driver, there will be a Network Controller device listed there with a little ! mark next to it.

Post the hardware ID for the network controller device, and I will post the links to the wifi and bluetooth drivers you need.

Use this guide to find the hardware ID for a device.

I have not found a device  need to be installed in the device manager.

I mean there is not any exclamation mark over there.

please help me.

If there is no device like I described, then there is a hardware problem with the wifi adapter.

The next thing to try is to remove and firmly reseat the wifi adapter.

Below is the link to the service manual, where you can find the wifi adapter removal and replacement procedure.

See chapter 6.

Leave the antenna cables attached to the card if you can when you remove it.   That will make it easier to install it.
