Windows 7 Windows 7 based Dell Inspiron fails to find Wireless access to Internet.

All seems well and my download connects to the internet when plugged in directly but does not find an active, validated, local wireless connection. The trouble shooter leads to "cable not connected" every time. Wireless is switched on, signal strenght is excellent and several other XP based laptops in the same area log on automatically.\

Any ideas?

Thanks,
