An exclamation point on the Wi-Fi icon indicates that the Wi-Fi connection has been made, but the Internet connection is being routed to another address.

In this state, local connections may continue to function, such as printing and Data Sharing; however, you will not be able to send email.

To use a captive portal network with LabQuest, first update to the latest software (LabQuest 2.1 or newer), then tap the radio icon next to the network connection.
