That sounds like the Intel(R) Proset software is not detecting the hardware correctly. A complete reinstall of Intel Proset and the drivers might fix this behavior.
We higly recommend using the set of drivers provided by the computer manufacturer for such cases.
- Do you even see it listed on device manager?
- Can you actually see any networks (Under Intel Proset software) if you press the "Scan for networks" option?
You may want to talk to Lenovo* for a warranty replacement if none of that works.
Anyhow, hope that helps a bit!
