Fig. 40. Sample wireless bridge network topology.
WARNING: Don’t let your network topology consisting of wireless bridges, Ethernet switches,
Ethernet links, and WDS links contain loops. If any loops exist, packets will circle around the loops
and network performance will be seriously degraded.

If external high-gain directional antennas are used, it’s difficult to align the antennas when the dis-
tance between the bridges is long.
To adjust the alignments of a pair of bridges’ directional antennas:
7. Connect each bridge to a computer via Ethernet.
8. Configure the date rate of each bridge to the lowest value, 1Mbps.
9. Fix the alignment of the antenna on one side.
10. Adjust the alignment of the antenna on other side by using response time information obtained
from PINGing (run PING.exe) the “fixed-side” computer.
11. Fine-tune the alignment of the antenna until you get a best response time.
