A Transitional Security Network (TSN) is a network that uses the Transitional Security Network Protocol that allows clients to authenticate with networks in the most secure way possible, based on the capabilities of their hardware and software. Computers capable of connecting using the WPA standard will be able to authenticate using a WPA password. Computers that do not meet the requirements to authenticate using WPA will use WEP instead.
The same password is used on all clients of the Transitional Security Network, regardless of the specific authentication method they use.
