To set up the remote building wireless access:
1 Make sure the AP8250 access points are running the latest
firmware.
To use WDS Bridging, the access points must be running firmware version 3.1.0 or later.
To download the latest firmware, go to the 3Com web site (www.3com.com).
2 Configure the access points with the same Radio and Encryption
settings.
Before physically installing the equipment, configure the access points with the same
Radio and Encryption settings. This configuration is done by connecting to the
Configuration Management System on the access point.
Note: For instructions on connecting to the Configuration Management System, see the
Wireless LAN Access Points User Guide.
a On the access point that is to be configured as the Root-Bridge, open the access point
Configuration Management System and click Advanced Setup.
b Open the Radio Settings page and set the following items:
Transmit antenna—set to the correct antenna port (usually port A, which is the port
that is closest to the LEDs). The transmit antenna must be set to the same port that
the antenna cable is connected to.
Radio Channel—disable the auto channel section, and set the desired radio channel
settings (for example, set the Radio Channel to 6).
