ZyXEL G-570S User's Guide
Be careful to avoid bridge loops when you enable bridging in the G-570S. 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 G-570Ss (in bridge mode) are connected to the same hub as shown next.

If your G-570S (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 40 Bridge Loop: Bridge Connected to Wired LAN

To prevent bridge loops, ensure that your G-570S is not set to bridge mode while connected to
both wired and wireless segments of the same LAN.
