Is that a USB WiFi Adapter? If so you will need to contact the maker's support.
Right Click Start Button - Device Manager
If it shows in Device Manager - Network Adapters - click on it - Drivers tab - Update driver - OK.
Please let us know the results and if you need further assistance.
I have the same problem,
I updated the drivers as you mentioned but still in the REALTEK 11n USB wireless LAN Utility, shows that no adapter is found. Please help!
