Bandwidth Select whether the VMG uses a wireless channel width of 20MHz or 40MHz.
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.
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.
Passphrase
Type
If you set security for the wireless LAN and have the VMG generate a password, the setting
in this field determines how the VMG generates the password.
Select None to set the VMG’s password generation to not be based on a passphrase.
Select Fixed to use a 16 character passphrase for generating a password.
Select Variable to use a 16 to 63 character passphrase for generating a password.
Passphrase Key For a fixed type passphrase enter 16 alphanumeric characters (0-9, A-Z, with no spaces). It
must contain both letters and numbers and is case-sensitive.
For a variable type passphrase enter 16 to 63 alphanumeric characters (0-9, A-Z, with no
spaces). It must contain both letters and numbers and is case-sensitive.
Wireless Network Settings
Wireless
Network Name
(SSID)
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 Select Basic (WEP) or More Secure (WPA-PSK, WPA2-PSK, WPA-WPA2-Personal) 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 in this screen.
Or you can select No Security to allow any client to associate this network without any data
encryption or authentication.
