LABEL DESCRIPTION
WMM of SSID1~4 Select On to have the VMG automatically give the wireless network (SSIDx) a priority level
according to the ToS value in the IP header of packets it sends. WMM QoS (Wifi MultiMedia
Quality of Service) gives high priority to voice and video, which makes them run more smoothly.
WMM
Automatic
Power Save
Delivery(APSD) Select this option to extend the battery life of your mobile devices (especially useful for small
devices that are running multimedia applications). The VMG goes to sleep mode to save power
when it is not transmitting data. The AP buffers the packets sent to the VMG until the VMG
"wakes up". The VMG wakes up periodically to check for incoming data.
Note: This works only if the wireless device to which the VMG is connected also
supports this feature.
Apply Click Apply to save your changes.
