Chapter 7 Wireless The following table describes the general wireless LAN labels in this screen. Table 16 Network Setting > Wireless > General LABEL DESCRIPTION Wireless Network Setup Bandwidth This shows the wireless band which 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. Control Sideband Passphrase Type 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. This is available for some regions when you select a specific channel and set the wireless channel width to 40MHz. Set whether the control channel (set in the Channel field) should be in the Lower or Upper range of channel bands. 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. Passphrase Key Select Variable to use a 16 to 63 character passphrase for generating a password. 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 The SSID (Service Set IDentity) identifies the service set with which a wireless device is Network Name associated. Wireless devices associating to the access point (AP) must have the same SSID. Max Clients Hide SSID Multicast Forwarding Max. Upstream Bandwidth Max. Downstream Bandwidth BSSID Enter a descriptive name (up to 32 English keyboard characters) for the wireless LAN. Specify the maximum number of clients that can connect to this network at the same time. 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. Select this check box to allow the VMG to convert wireless multicast traffic into wireless unicast traffic. Specify the maximum rate for upstream wireless traffic to the WAN from this WLAN in kilobits per second (Kbps). Specify the maximum rate for downstream wireless traffic to this WLAN from the WAN in kilobits per second (Kbps). This shows the MAC address of the wireless interface on the VMG when wireless LAN is enabled. VMG3925-B10A User's Guide 87
