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 hub.

Figure 49 Bridge Loop: Two Bridges Connected to Hub

• 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.

Figure 50 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.
