|I'd try manually defining a connection - if, you see WEP and WPA, but not WPA2 as a "Network Authentication" option, then:|
- Use Windows Update to search for hardware driver updates applicable to your wireless adapter,
- Determine the specific adapter you have, and search the manufacturer's web-site for info and newer drivers [for your OS.]
It's possible that your OS will need a "minimum" service-pack to support a newer driver.
If you find your laptop's wireless adapter is simply incapable of supporting WPA2 (is it internal, MiniPCI?), it may be possible to replace adapter with a newer adapter which does support WPA2. When going through this procedure (for a circa 2003 notebook,) I spent about $60US on a MiniPCI wireless adapter, though, it looks like they're much cheaper these days!
