Wireless > Advanced Wireless Settings
Configure the Bridge’s advanced wireless functions.
These settings should only be adjusted by an expert
administrator as incorrect settings can reduce wireless
performance.
Wireless > Advanced Wireless Settings
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

Troubleshooting
Your computer or other wired, Ethernet device cannot
communicate with the wireless router.
Access
the
web-based
utility
of
the
Bridge
(refer
to
1.
Chapter 3: Advanced Configuration
,
page 3
).
On
the
2.
Basic Wireless Settings
screen, make sure the
Network Name (SSID) matches the name of your
wireless network.
Make sure the security settings (WPA, WPA2, or WEP)
3.
match the security settings of your wireless network.
The Bridge’s IP address needs to be changed.
If the Bridge is connected to a network with a DHCP server
(usually the network router), then the Bridge will obtain
its IP address from the DHCP server. If there is no DHCP
server, then the Bridge will use its default, static IP address,
169.254.1.250
.
If you want the Bridge to always use a static IP address,
then follow these instructions:
Access
the
web-based
utility
of
the
Bridge
(refer
to
1.
Chapter 3: Advanced Configuration
,
page 3
).
Click the
2.
Network Setup
tab.
From the

Network Connection Type
drop-down menu,
select
Static IP
.
Complete
the
4.
Static IP Address
,
Subnet Mask
, and
Default Gateway
fields.
Click
5.
Save Settings
.
The Bridge-enabled computer or other wired, Ethernet
device will not communicate with another wireless-
enabled device (such as a computer or printer).
Check the following:
Make sure the wireless-enabled device is on the same
wireless network as the computer or other wired,
Ethernet device connected to the Bridge.
Make sure that the same Network Name (SSID) is used
for all devices on the wireless network.
Make sure all devices are on the same IP network,
using compatible IP addresses.
The web-based utility does not accept your password.
Check the following:
The password is case-sensitive. Make sure that you are
using the correct case(s) when entering the password.
If you forget your password, you can reset the Bridge
to its factory defaults.
Press
and
hold
the
Bridge’s
Reset
button
for
approximately five seconds; the password will be reset
to its factory default,
admin
. All other Bridge settings
will be reset to the factory defaults as well. (To access
the web-based utility, enter
admin
in the
Password
field.)
After you make changes through the web-based utility,
the new settings are not displayed on-screen.
On your web browser, click
Refresh
. If the new settings
are not displayed, then follow these instructions:
Unplug the power adapter from the Bridge.
1.
Wait five seconds, and then plug the power adapter
2.
back into the Bridge.
