Wireless LAN
Select
Ena b le
to activate the 2.4GHz and/or 5GHz wireless LAN. Select
Disa b le
to turn it off.
Name (SSID)
The SSID (Service Set IDentity) identifies the Service Set with which a wireless client is
associated. Enter a descriptive name (up to 32 printable characters found on a typical English
language keyboard) 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.
Channel Selection
Select a channel from the drop-down list box. The options vary depending on the frequency
band and the country you are in.
This option is only available if
A uto C ha nne l Se le c tio n
is disabled.
Operating
Channel
This displays the channel the NBG6604 is currently using.
Channel Width
Select the wireless channel width used by NBG6604.
A standard 20MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps
(5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to
300Mbps (2.4GHz) or 450Mbps (5GHz).
Because not all devices support 40 MHz channels, select
A uto 20/ 40MHz
to allow the NBG6604
to adjust the channel bandwidth automatically.
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.
802.11 Mode
If you set
Ba nd
to
2.4G Hz
, you can select from the following:
•
802.11b
: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate
with the NBG6604. In this mode, all wireless devices can only transmit at the data rates
supported by IEEE 802.11b.
•
802.11g
: allows IEEE 802.11g compliant WLAN devices to associate with the Device. IEEE
802.11b compliant WLAN devices can associate with the NBG6604 only when they use the
short preamble type.
•
802.11b g
: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate
with the NBG6604. The NBG6604 adjusts the transmission rate automatically according to
the wireless standard supported by the wireless devices.
•
802.11n
: allows IEEE 802.11n compliant WLAN devices to associate with the NBG6604. This
can increase transmission rates, although IEEE 802.11b or IEEE 802.11g clients will not be
able to connect to the NBG6604.
•
802.11g n
: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to associate
with the NBG6604. The transmission rate of your NBG6604 might be reduced.
•
802.11 b g n
: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to
associate with the NBG6604. The transmission rate of your NBG6604 might be reduced.
If you set
Ba nd
to
5G Hz
, you can select from the following:
•
802.11a
: allows only IEEE 802.11a compliant WLAN devices to associate with the NBG6604.
•
802.11a / a n
: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to
associate with the NBG6604. The transmission rate of your NBG6604 might be reduced.
•
802.11a / a n/ a c
: allows IEEE802.11n, IEEE802.11a and IEEE 802.11c compliant WLAN devices
to associate with the NBG6604.
