Wireless, roaming laptops are NOT logged until you create at least one access point of your office via 'Maps\Create Access Point'.
This is because home use of roaming laptops is not logged. In order to distinct between office and home use, the server needs to evaluate incoming data. It compares the access points in each sent data package with the access points you have created.
And so, if the server finds a match, that is, if one of the office access points you created is present in the received data package, the server starts logging.
If the server finds none (if you have not yet added an office access point), the server simply ignores the incoming data package.
