• Atheros AR9285/AR9485 — the most common option.
• Broadcom 4313 — less common, but found in some games.
• Intel WiFi Link 1000 — in modifications for corporate clients.

You can download official drivers from the Lenovo website (support section for B560), but they are often not suitable for Windows 7. Alternative sources:

• 🔗 Intel's official website (for Intel modules).
• 🔗 Atheros Driver Archive.
• 🔗 Microsoft Update Catalog (search by device ID).

How to install the driver manually:

1. Download the archive with the driver and unzip it.
2. Open device Manager (Win + R → devmgmt.msc).
3. Find the device with an exclamation mark (usually in the Network adapters or Other devices).
4. Right click → Update drivers → Search for drivers on this computer → specify the folder with the unpacked driver.

How do I find the device ID to search for a driver?

Open device Manager, right-click on the unknown device → Properties → tab Intelligence → select Equipment ID. Copy the first line (for example, PCI\VEN_168C&DEV_002B) and enter it into the search on the manufacturer's website or in the Microsoft catalog.
