Hi:

For the wireless network adapter in your model, you need this wireless driver.

You will also need the Broadcom bluetooth driver for that card from your notebook's support and driver page.

But the bluetooth driver provided in Device support page shows error. But I got the Driver from another Model with Same Bluetooth Device 🙂
