1.2. Wireless Performance Considerations
There are a number of factors that can impact the range of wireless devices.
1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at
an angle. The more material the signal has to pass through the more signal you will lose.
2. Keep the number of obstructions to a minimum. Each obstruction can reduce the range of a
wireless device. Position the wireless devices in a manner that will minimize the amount
of obstructions between them.
3. Building materials can have a large impact on your wireless signal. In an indoor
environment, try to position the wireless devices so that the signal passes through less
dense material such as dry wall. Dense materials like metal, solid wood, glass or even
furniture may block or degrade the signal.
4. Antenna orientation can also have a large impact on your wireless signal. Use the wireless
adapter’s site survey tool to determine the best antenna orientation for your wireless
devices.
5. Interference from devices that produce RF (radio frequency) noise can also impact your
signal. Position your wireless devices away from anything that generates RF noise, such
as microwaves, radios and baby monitors.
6. Any device operating on the 2.4GHz or 5GHz frequency will cause interference. Devices
such as 2.4GHz or 5GHz cordless phones or other wireless remotes operating on the
2.4GHz or 5GHz frequency can potentially drop the wireless signal. Although the phone
may not be in use, the base can still transmit wireless signal. Move the phone’s base
station as far away as possible from your wireless devices.
If you are still experiencing low or no signal consider repositioning the wireless devices or
installing additional access points. The use of higher gain antennas may also provide the
necessary coverage depending on the environment.

IEEE 802.1x is an authentication protocol. Every user must use a valid account to login to
this Access Point before accessing the wireless LAN. The authentication is processed by a
RADIUS server. This mode only authenticates users by IEEE 802.1x, but it does not
encrypt the data during communication.
WEP Encryption
When you select 64-bit or 128-bit WEP key, you have to enter WEP keys to encrypt data.
You can generate the key by yourself and enter it. You can enter four WEP keys and select
one of them as a default key. Then the router can receive any packets encrypted by one of
the four keys. WEP provides basic level or security, if you would like to use higher security
encryption, please consider WPA2 encryption.
22

Authentication Type: There are two authentication types: "Open System" and "Shared
Key". When you select "Open System", wireless stations can associate with this
wireless router without WEP encryption. When you select "Shared Key", you should
also setup a WEP key in the "Encryption" page. After this has been done, make
sure the wireless clients that you want to connect to the device are also setup with the
same encryption key.
Key Length: You can select the WEP key length for encryption, 64-bit or 128-bit. The
larger the key will be the higher level of security is used, but the throughput will be
lower.
Key Type: You may select ASCII Characters (alphanumeric format) or Hexadecimal Digits
(in the "A-F", "a-f" and "0-9" range) to be the WEP Key.
Key1 - Key4: The WEP keys are used to encrypt data transmitted in the wireless network.
Use the following rules to setup a WEP key on the device. 64-bit WEP: input 10-digits
Hex values (in the "A-F", "a-f" and "0-9" range) or 5-digit ASCII character as the
encryption keys.
128-bit WEP: input 26-digit Hex values (in the "A-F", "a-f" and "0-9" range) or 13-digit
ASCII characters as the encryption keys.
Click Apply at the bottom of the screen to save the above configurations. You can now
configure other sections by choosing Continue, or choose Apply to apply the settings and
reboot the device.

The Broadband router provides extensive firewall protection by restricting connection
parameters, thus limiting the risk of hacker attacks, and defending against a wide array of
common Internet attacks. However, for applications that require unrestricted access to the
Internet, you can configure a specific client/server as a Demilitarized Zone (DMZ).
7.2. Advanced
If you are using some VPN access for your work or other purpose, you can enable the
options here to pass the VPN packets correctly. These options are enabled by default, the
router is not a VPN server or client, it only pass through the packets.
Note: For VPN connections, it might require to open some ports when you run your PC
behind a router. For port information, please refer to each VPN software’s help site.
7.3. Demilitarized Zone (DMZ)
If you have a client PC that cannot run an Internet application (e.g. Games) properly from
behind the NAT firewall, then you can open up the firewall restrictions to unrestricted
two-way Internet access by defining a DMZ Host. The DMZ function allows you to re-direct
all packets going to your WAN port IP address to a particular IP address in your LAN. The
difference between the virtual server and the DMZ function is that the virtual server
re-directs a particular service/Internet application (e.g. FTP, websites) to a particular LAN
client/server, whereas DMZ re-directs all packets (regardless of services) going to your
WAN IP address to a particular LAN client/server.
