Using The Client Utility - Cabletron Systems RoamAbout Access Point Manual

Using the Client Utility

This procedure requires the RoamAbout Client Utility on a RoamAbout client. For
information about a client utility window, press <F1> while in that window.
1. Start the RoamAbout Client Utility by clicking Start from the Taskbar then selecting
Programs → RoamAbout → RoamAbout Client Utility. Click the More button if the
Status/Functions window is not displayed.
2. Select Link Test from the Status/Functions window.
If connected to an infrastructure network, the test partner is the associated Access
Point. If configured for an ad-hoc network, select another client in the network to be
the test partner then select the Test Results tab.
3. Check the Signal-to-Noise (SNR) indicator, which changes color according to the
communications quality as follows:
— Green. Communications quality is good.
— Yellow. Communications quality is adequate. Optionally, click the Advice button
in the Link Test window for tips on improving communications quality.
— Red. Communications quality is poor and requires user intervention.
4. Check the Signal Level and Noise Level indicators if the SNR indicator is red.
A high noise level indicates that you may have one or more devices emitting radio
signals in the same frequency band as the client. Run the Link Test on other clients to
determine the extent of the noise. The source of the noise may be closest to the device
that has the highest noise level. Try to eliminate or move the source of the noise.
A low signal level indicates that the client and the test partner may be too far apart or
there may be obstructions between them. If possible, remove the obstructions, move
the devices closer, or use the optional Range Extender antenna described on page 1-15.
The Link Test window has an Advice button. Click this button for specific troubleshooting
suggestions.
