Bandwidth
Select whether the Device 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 Device generate a password, the
setting in this field determines how the Device generates the password.
Select
None
to set the Device’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.
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.
Client Isolation
Select this to keep the wireless clients in this SSID from communicating with each other
through the Device.
MBSSID/LAN
Isolation
Select this to keep the wireless clients in this SSID from communicating with clients in other
SSIDs or wired LAN devices through the Device.
Select both
Client Isolation
and
MBSSID/LAN Isolation
to allow this SSID’s wireless
clients to only connect to the Internet through the Device.
Enhanced
Multicast
Forwarding
Select this check box to allow the Device to convert wireless multicast traffic into wireless
unicast traffic.
BSSID
This shows the MAC address of the wireless interface on the Device when wireless LAN is
enabled.
Maximum
Bandwidth
Specify the maximum rate for wireless traffic in kilobits per second (Kbps).
Security Level
Security Mode
Select
Basic (WEP)
or
More Secure (WPA(2)-PSK, WPA(2))
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 Device. 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.
