Chapter 6 Wireless Configuration
Be careful to avoid bridge loops when you enable bridging in the ZyXEL Device. Bridge loops
cause broadcast traffic to circle the network endlessly, resulting in possible throughput
degradation and disruption of communications. The following examples show two network
topologies that can lead to this problem:
• If two or more ZyXEL Devices (in bridge mode) are connected to the same switch (as
shown next).

Figure 35 Bridge Loop: Two Bridges Connected to Switch

• If your ZyXEL Device (in bridge mode) is connected to a wired LAN while
communicating with another wireless bridge that is also connected to the same wired LAN
(as shown next).

Figure 36 Bridge Loop: Bridge Connected to Wired LAN

To prevent bridge loops, ensure that you enable STP in the Wireless screen or your ZyXEL
Device is not set to bridge mode while connected to both wired and wireless segments of the
same LAN.
To have the ZyXEL Device act as a wireless bridge only, click WIRELESS > Wireless and
select Bridge/Repeater as the Operating Mode.
