7.6 Channel Status

Use the Channel Status screen to scan the number of devices which are using 2.4G and/or 5G WiFi
channels and view the results. Click Network Setting > Wireless > Channel Status. The screen appears as
shown. Click 2.4G Scan and/or 5G Scan to scan the 2.4G and/or 5G wireless band channels. You can
view the results in the corresponding Channel Scan Result section.
Note: The 2.4G Scan or 5G Scan button only works when the VMG uses 20 MHz for the wireless
channel width. You can go to the Network Setting > Wireless > Advanced screen, and
then change the channel width setting in the Bandwidth field.
Chapter 7 Wireless
DESCRIPTION
Select Enable to have the VMG automatically give the wireless network 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.
Note: At the time of writing, WMM is enabled by default and it is not changeable.
Select Enable 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.
This option is only available for the 5G band. Disabling it will force Channel in Network Setting >
Wireless > General to be set to Auto.
Enabling this option allows the use of DFS channel, ranging from 52~144, which may interfere
with some RADAR devices. If your device is operating near an area known to have RADAR
devices, it is recommended to disable DFS Channel to avoid interfering with their signal.
Note: As of this writing, this option is not available for VMG9827-B50A.
Select Enable to allow accelerated and simultaneous WiFi service when there are multiple MU-
MIMO (Multi User-Multiple input, Multiple Output) ready devices connected to the VMG.
