Wireless-N Ethernet Bridge with Dual-Band
NOTE:
The settings on the
Advanced Wireless
Settings
screen are designed for advanced users
only.
Advanced Wireless
Use LDPC
Low-Density Parity-Check Code (LDPC) enables
or disables error correction to reduce the probability of
data loss in noisy channels. The Rate Adaptation algorithm
automatically disabled LDPC coding when working at high
PHY rates (higher than 162). To use the LDCP advanced
error correction scheme, keep the default,
Yes
. Otherwise,
select
No
.
ERP Protection Type
This option configures protection
of OFDM packets despite the presence of 802.11b stations
within the wireless network. By sending RTS/CTS or
CTS2Self packets in 802.11b rates, the Bridge informs
the wireless network that OFDM packets are going to
be transferred and protects the packets in the wireless
network. The RTS/CTS and CTS2Self packets create
overhead, which may result in lower throughputs.
The RTS/CTS option provides better coverage but lower
throughputs when compared to CTS2Self, because the
RTS/CTS option includes acknowledgement from the
receiving device. To use the RTS/CTS option, keep the
default,
RTS/CTS
. The None option may cause collisions
between OFDM and CCK packets. To use the None option,
select
None
. To use the CTS2Self option, select
CTS2Self
.
11n Protection Type
This option configures protection
from non-High Throughput (HT) devices within the
wireless network. In case the wireless router (or access
point) detects an association of a non-HT legacy device,
it will signal all the HT devices to use RTS/CTS or CTS2Self
mechanisms before each data transmission. This feature
also supports all 802.11n standard protections, including
MIMO.
The RTS/CTS option provides better coverage but lower
throughputs when compared to CTS2Self, because the
RTS/CTS option includes acknowledgement from the
receiving device. To use the RTS/CTS option, keep the
default,
RTS/CTS
. The None option may cause collisions
between HT and legacy packets. To use the None option,
select
None
. To use the CTS2Self option, select
CTS2Self
.
Percentage of maximal transmit power
This option
sets the percentage of maximal transmit power relative
to the regulatory domain restrictions. For example, if the
regulatory domain restriction allows transmissions of
up to 20 dB, then setting the percentage at 50% allows
maximal transmit power of 10 dB. Select the percentage
you want to use:
12%
,
25%
,
50%
, or
100%
. The default
is
100%
.
QoS Classification Type
This option sets 802.1D or
802.1Q mapping from the IP DSCP/TOS field to WMM
priorities (Background, Best Effects, Video, Voice). Keep
the default,
802.1D
, or select
802.1Q
, which is used by
some IPTV streams.

Network Setup > Basic Network Settings
Change the Bridge’s wired, Ethernet network settings.
Network Setup > Basic Network Settings (Automatic Configuration -
DHCP)
Network Setup > Basic Network Settings (Static IP)
Basic Network Settings
This section determines if the Bridge’s IP address is
obtained automatically from a DHCP server, such as your
network router (Automatic Configuration - DHCP), or set
manually (Static IP).
Network Connection Type
If your network has a
DHCP server, such as your network router, assigning IP
addresses to your network devices, then keep the default,
Automatic Configuration - DHCP
. The Bridge will request
an IP address from the DHCP server (usually the network
router). If no DHCP server is found, then the Bridge will use
its default static IP address,
169.254.1.250
, until it detects
a DHCP server and is assigned a dynamic IP address.
If you want to set a permanent static IP address for the
Bridge, then select
Static IP
.
If you select Static IP, then complete the following fields:
Static IP Address
•
Enter a unique IP address that will
be used to access the web-based utility.
Subnet Mask
•
Enter the subnet mask of your wired
network.
