Channel
Set the channel depending on your particular region.
Select a channel or use
Auto
to have the Device automatically determine a channel to use.
If you are having problems with wireless interference, changing the channel may help. Try
to use a channel that is as many channels away from any channels used by neighboring APs
as possible. The channel number which the Device is currently using then displays next to
this field.
The available channels vary depending on the bandwidth you select in the
Bandwidth
field.

Bandwidth
Select whether the Device uses a wireless channel width of
20MHz
,
40MHz
, or
80MHz
(available for 5 GHz networks only).
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, and a 80MHz
channel uses only one channel and offers speeds of up to 433 Mbps.
A wider band enables higher transmittion rate. A 40MHz (channel bonding or dual channel)
channel bonds two adjacent radio channels to increase throughput. An 80MHz channel
bonds two adjacent 40 MHz channels to get even higher data rates. The wireless clients
must also support 40 MHz or 80 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
or
80MHz
. 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.
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.
Enhanced
Multicast
Forwarding
Select this check box to allow the Device 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).
