Step 2: Prevent Loops if Connecting Many AP's
When many APs are linked in this manner, undesired loops may form to lower overall WLAN
performance. To prevent such occurrence, please make sure Layer 2 STP is enabled.
To turn on this feature, please click on the System and then Network Interface tab.
Please select Enable in the field labeled Layer2 STP. This will prevent data from looping or a broadcast storm.
Click SAVE when completed, and then Reboot to allow updated settings to take effect.
