If this is the original Intel Wireless N2200 that came with the PC, can you try to:
1. Reboot the computer and repeatedly tap F2 to boot into the BIOS, when you're in, press F9 to load BIOS to defaults and press F10 to save and exti BIOS.
2. If you get the same error, try to Access the Startup Settings and choose Disable driver signature enforcement - if this fixes the problem, it's probably due to a not digitally signed driver, try to follow this guide.
If the above steps doesn't work, the BIOS might be blacklisting this wifi adapter as discussed in this thread or simply getting defective (you will need to contact lenovo for service to get this wifi card replaced).
Hope this helps.
