OPTIMIZING AN AD HOC INSTALLATION
You can optimize an ad hoc installation by adjusting antenna positions slightly to improve the radio signal between bridges. The following tools help you to optimize the installation:
■The device manager can display a dynamic graphical representation of the bridge’s received signal strength indication (RSSI). By monitoring the RSSI while making antenna adjustments, you can ensure optimal placement.
■The configuration Connection Status page displays the bridge’s basic service set identification (BSSID) and a static RSSI value that you can refresh as needed.
■The configuration Wireless Network page allows you to specify a BSSID, if necessary.
To monitor signal strength, the bridges must be set to the same BSSID and RSSI broadcasting must be enabled. In the factory default configuration, the BSSID is generated automatically and RSSI broadcasting is disabled.
To use the device manager RSSI Monitor:
1Install the Wireless Infrastructure Device Manager (version 1.2.0.9 or later) from the 3Com installation CD.
2Launch the device manager (Start /Programs /3Com Wireless/Wireless Infrastructure Device Manager).
3In the device manager window, launch the first bridge configuration and configure for ad hoc mode.
Enable RSSI broadcasting as follows:
a In the main menu under System Configuration, click Wireless Network.
b In the Wireless Network page, click the link to go to advanced wireless network configuration.
c In the Advanced Wireless Network page, click the Broadcast RSSI On radio button, and click Save.
dNote the bridge BSSID.
In the main configuration menu under System Status, click Connection Status. The status window shows the BSSID.
4Return to the device manager and repeat step 3 for the second bridge. Make sure that both bridges are using the same BSSID.
If the bridges are not using the same BSSID, specify the BSSID on both bridges as follows:
a In the Wireless Network page, select the following Network Mode:
