LABEL DESCRIPTION
Wireless
Wireless Select Keep 2.4G and 5G wireless name the same to give the same SSID and password to both
2.4G and 5G wireless networks. The SSID and password of the 2.4G wireless network will be used.
Wireless Network Setup
Band This shows the wireless band that this radio profile is using. 2.4GHz is the frequency used by IEEE
802.11b/g/n wireless clients while 5GHz is used by IEEE 802.11a/ac wireless clients.
Wireless You can Enable or Disable the wireless LAN in this field.
Channel Use Auto to have the VMG automatically determine a channel to use.
Bandwidth Select whether the VMG uses a wireless channel width of 20MHz , 40MHz or 80MHz .
A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a 40MHz channel
uses two standard channels and offers speeds of up to 300 Mbps.
40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase
throughput. The wireless clients must also support 40 MHz. It is often better to use the 20 MHz
setting in a location where the environment hinders the wireless signal.
An 80MHz channel groups adjacent 40MHz channels into pairs to increase bandwidth even
higher.
Select 20MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
Control
Sideband This is available for some regions when you select a specific channel and set the Bandwidth field
to
40MHz . Set whether the control channel (set in the Channel field) should be in the Lower or
Upper range of channel bands.
Wireless Network Settings
Wireless
Network Name The SSID (Service Set IDentity) identifies the service set with which a wireless device is associated.
Wireless devices associating to the access point (AP) must have the same SSID.
Enter a descriptive name (up to 32 English keyboard characters) for the wireless LAN.
Max Clients Specify the maximum number of clients that can connect to this network at the same time.
Hide SSID Select this check box to hide the SSID in the outgoing beacon frame so a station cannot obtain
the SSID through scanning using a site survey tool.
Multicast
Forwarding Select this check box to allow the VMG to convert wireless multicast traffic into wireless unicast
traffic.
Max. Upstream
Bandwidth Specify the maximum rate for upstream wireless traffic to the WAN from this WLAN in kilobits per
second (Kbps).
Max.
Downstream
Bandwidth Specify the maximum rate for downstream wireless traffic to this WLAN from the WAN in kilobits
per second (Kbps).
BSSID This shows the MAC address of the wireless interface on the VMG when wireless LAN is enabled.
Security Level
Security Mode Select More Secure (WPA(2)-PSK) to add security on this wireless network. The wireless clients
which want to associate to this network must have same wireless security settings as the VMG.
When you select to use a security, additional options appears on this screen.
Or you can select No Security to allow any client to associate this network without any data
encryption or authentication.
See the following sections for more details about this field.
