This is a point-to-multipoint bridging LAN for networking eight serial devices (air quality monitors) to a central Windows box for real-time wireless data acquisition. Thus far, I have configured a single Aironet 1310 as the root bridge (RB: 220.127.116.11, 255.255.0.0) at the Windows box (PC: 18.104.22.168, 255.255.0.0) and three Aironet 1310s as non-root bridges (NRB1: 22.214.171.124; NRB2: 126.96.36.199; NRB3: 188.8.131.52). When the system's working, each of the NRBs will connect to an ethernet-to-serial device server with its own IP, and the serial devices will connect to the device servers as COM2-COM9, respectively. Each node in this network has an external antenna, an omni at the RB and directional/Yagi antennae at the NRBs. Distances are short, hundreds of meters, so power will not be the limiting factor. (We could have done this with Zigbee but decided to overdesign for reliability.)
After assigning IP addresses to all four bridges using the command-line interface, and with the RB connected to an ethernet hub/switch, we configured each of the NRBs by connecting them to the same hub/switch and using the browser interface. We used the document at
and followed it to the letter to configure first the RB, then the NRBs.
After configuring all four bridges, and while all four were still hard-wired together through the hub/switch, all four bridges showed the proper associations in the "State" column of the web interface under "Association." To test the wireless links we disconnected the three NRBs from the hub/switch by removing the ethernet cables, leaving the RB connected to the hub/switch (naturally) to maintain connection to the host PC. We then refreshed all associations.
On the RB web interface, all three NRBs showed up with the proper IP addresses, but the "State" fields showed "Attempting Association" or something like that rather than "EAP-Associated."
All three NRB web interfaces disappeared because the links were lost. I tried to PING each of the IP addresses using a DOS command, but all three timed out.
So, in short, the RB can "see" all three NRBs and "knows" they're there; but the association does not complete. What are my options for diagnosing the problem?
Thanks in advance...
