Abstract: A method of connecting a user computing device to a wireless network comprises establishing a wireless connection between the user computing device and a first wireless network. The user provides identifying information to a server via the first wireless network. In response to the server authenticating the user and upon successful authorisation of the user having the appropriate rights, the user receives access information for a second wireless network from the server. The user computing device establishes a wireless connection to the second wireless network using the received access information. The method has the advantage that the first wireless network can be easily discoverable, whereas the second wireless network can have an enhanced level of security.
