Figure 6   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.

In AP+Bridge mode, the ZyXEL Device supports both AP and bridge connection at the same 
time.
Using AP + Bridge mode, your ZyXEL Device can extend the range of the WLAN.  In the 
figure below, A and B act as AP + Bridge devices that forward traffic between associated 
wireless workstations and the wired LAN.
When the ZyXEL Device is in AP+Bridge mode, security between APs (the Wireless 
Distribution System or WDS) is independent of the security between the wireless stations and 
the AP. If you do not enable WDS security, traffic between APs is not encrypted. When WDS 
security is enabled, both APs must use the same pre-shared key. See 

for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless stations 
and the ZyXEL Device.
