Broadcast Network Name (SSID): Enable/Disable the SSID broadcast function. This function
is used to control the broadcast status of all SSIDs. If this function is disabled, all SSIDs you
had set up for the router will be hidden. To cancel the hidden status for the specific SSID, you
can uncheck the “Hidden” option in the back of your desired SSID.
AP Isolation: Enable/Disable this function. Create a separate virtual network for your wireless
network. When this feature is enabled, each of your wireless clients will be in its own virtual
network and will not be able to communicate with each other. You may want to utilize this
feature if you have many guests that frequent your wireless network.
MBSSID AP Isolation: Enable/Disable the MBSSID AP Isolation function. The router supports
multiple SSIDs. You can decide whether the clients associated to different SSIDs on the device
can see each other or not. Enable the option to block it. Default is “Disable”.

spectrum to handle communication between clients. Some channels in your area may have
interference from other electronic devices. Choose the clearest channel to help optimize the
performance and coverage of your wireless network. If you select AutoSelect, the router
automatically finds the channel with least interference and uses that channel for wireless
networking.

decodes both Mixed Mode packets and legacy packets.
Green Field mode: The device transmits HT packets without legacy compatible part. But
the device receives and decodes both Green Field and legacy packets.
