1. Introduction
1.1. Summary
TEW-671BR is a Dual Band Concurrent Wireless 11N Broadband Router with dual CPU
that offers user unprecedented network performance. WMM support boosts streaming
and multimedia intensive services. It supports 2.4GHz band under 802.11 b/g/n modes
while providing 5GHz band to guarantee an interference-free network access.
Multiple SSID provides advance users to manage multiple users of various needs. TX
power control enables flexible transmission tuning for different installation needs and
prevents malicious eaves-dropping. Isolation, filter, firewall and full coverage of security
standards promise a secure network environment.
Dual CPU operates work simultaneously therefore users can enjoy gaming, music or HD
video on 5GHz band while web-surfing or emailing on 2.4GHz. It also provides with
built-in 4-port full-duplex 10/100 Fast Switch that allows wired Ethernet for standard PC
and other network devices. TEW-671BR is definitely the optimal choice for both SOHO
and small business entities.

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.

14
5.2. Dynamic IP
Use the MAC address when registering for Internet service, and do not change it unless
required by your Internet Services Provider (ISP). If your ISP used the MAC address of the
Ethernet card as an identifier, connect only the PC with the registered MAC address to the
broadband router and click the Clone MAC Address button. This will replace the current
MAC address with the already registered Ethernet card MAC address.
Host Name: This is optional.
MAC address: The default value is set to the WAN’s physical interface of the broadband
router. Most Dynamic IP connections do not require MAC Address therefore you can
leave this section blank if you think this does not apply to your account.

Service Name: This is normally optional.
Maximum Transmission Unit (MTU): This is the maximum size of the packets.
Type: Enable the Auto-reconnect option to automatically re-establish the connection
when an application attempts to access the Internet again.
Idle Timeout: This is a maximum period of time for which the Internet connection is
maintained during inactivity. If the connection is inactive for longer than the
Maximum Idle Time, it will be dropped.
Note: you can leave the MTU, Authentication type, Type and idle Timeout settings as
default if you do not know what to choose.

16
5.5. PPTP
