RoamAbout Client Utility
Diagnose Card
The card diagnostics enables you to:
• Test the RoamAbout PC Card.
• Display a set of communication statistics.
• Display the configuration settings of the PC Card. The configuration settings can only
be displayed when the client utility is in enhanced mode, which you can enable by
clicking the Options button in the Status/Functions window.
Run the card test only in situations where the Status/Functions window reports a card
failure or when you suspect a configuration mismatch. When contacting RoamAbout
technical support, the card test results may help the support representative determine the
cause of a malfunctioning device.
Running the card test may temporarily disrupt the client from communicating with the
network. In exceptional cases, you may lose the network connection.
Link Test
Use the RoamAbout Client Utility Link Test window (Figure 4-4) to investigate the
specific link between the RoamAbout client and its test partner. If connected to a
infrastructure network, the test partner is the associated Access Point. If configured for an
ad-hoc network, you can select another client in the network to be the test partner.
To monitor the communications quality of the client connection to the network, Link Test
actively exchanges test messages with the test partner.
When you run the Link Test while roaming through a network environment with multiple
Access Points, the link test partner (Access Point) changes as you move from cell to cell.
The link test mode enables you to investigate:
• The communications quality of the radio connection, which is the primary indicator of
wireless performance.
• The data throughput efficiency of the radio connection, which is the secondary
indicator of wireless performance.
