Firmware Restoration
This utility will automatically search out failed ASUS Wireless Routers
and upload a firmware that you specify. The process takes about 3 to 4
minutes and during this process the PWR, AIR, and WAN LEDs will remain
lit while the LAN LED will flash slowly.
The Firmware Restoration utility is an emergency rescue tool to restore a
ASUS Wireless Router which has failed during a previous firmware upload.
A failed firmware upgrade will cause the ASUS Wireless Router to enter a
failure mode, waiting for the user to use the Firmware Restoration utility to
find and upload a new firmware. This is not a firmware upgrade utility and
cannot be used on a working ASUS Wireless Router. Normal firmware
upgrades must be done through the web manager.
Using a Hub
If you have problems upload a firmware while using a network hub, try
connecting your computer directly to the LAN port. Either 10Base-T or
100Base-TX connections will work.

Wireless Performance
This section provides the user with ideas for how to improve the performance
of a ASUS Wireless network.
Site Topography
For optimal performance, locate wireless mobile clients and the ASUS
Wireless Routers away from transformers, heavy-duty motors, fluorescent
lights, microwave ovens, refrigerators, and other industrial equipment.
Signal loss can occur when metal, concrete, walls or floors block
transmission. Locate the ASUS Wireless Routers in open areas or add the
ASUS Wireless Routers as needed to improve coverage.
Microwave ovens operate in the same frequency band as the ASUS Wireless
Router. Therefore, if you use a microwave within range of the ASUS
Wireless Router you may notice network performance degradation.
However, both your microwave and your the ASUS Wireless Router will
continue to function.
Site Surveys
A site survey (utility provided with the WLAN PC card and CF card)
analyzes the installation environment and provides users with
recommendations for equipment and its placement. The optimum placement
differs for each model.

Range
Every environment is unique with different obstacles, barriers, materials,
etc. and, therefore, it is difficult to determine the exact range that will be
achieved without testing. However, has developed some guidelines to
estimate the range that users will see when the product is installed in their
facility, but there are no hard and fast specifications.
Radio signals may reflect off of some obstacles or be absorbed by others
depending on their construction. For example, with two 802.11b radios,
you may achieve up to 1000' in open space outdoors where two devices
have a line of sight, meaning they see each other with no obstacles. However,
the same two units may only achieve up to 300' of range when used indoors.
The IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5 Mbps,
2 Mbps, and 1 Mbps. Operation at 1 Mbps provides greater range than
operation at 11 Mbps. The ASUS Wireless Router will automatically adjust
the data rate to maintain a usable radio connection.
Therefore, a client that is close to the ASUS Wireless Router may operate
at 11 Mbps while a client that is on the fringe of coverage may operate at 1
Mbps. As mentioned earlier, you can configure the data rates that the ASUS
Wireless Router will use. Note that if you limit the range of data rates
available to the ASUS Wireless Router, you may reduce the effective
wireless range of the ASUS Wireless products.

Troubleshooting
The ASUS Wireless Router is designed to be very easy to install and operate.
However, if you experience difficulties, use the information in this chapter
to help diagnose and solve problems. If you cannot resolve a problem, contact
Technical Support, as listed on the front of this manual.
Common Problems and Solutions
Problem
ASUS Wireless Router does not power up:
Solution
Check for faulty the ASUS Wireless Router power supply by measuring
the output voltage with an electrical test meter.
Check failed AC supply (power outlet)
Problem
Cannot communicate with the ASUS Wireless Router through a wired
network connection.
Solution
Verify network configuration by ensuring that there are no duplicate IP
addresses. Power down the device in question and ping the assigned IP
address of the device. Ensure no other device responds to that address.
Check that the cables used have proper pin outs and connectors or use
another LAN cable.

Problem
The ASUS Wireless Router Web Manager still cannot find or connect to the
ASUS Wireless Router after verifying the IP address and LAN cable, changes
cannot be made, or password is lost.
Solution
In case the ASUS Wireless Router is
inaccessible, you can restore the ASUS
Wireless Router’s factory default
settings. Use a straightened paper clip to press the button located in the
hole labeled “Reset” on the back of the ASUS Wireless Router and keep it
depressed over 5 seconds. The LEDs will flash when reset is successful.
Reset to Defaults
The following are factory default values. These values will be present when you
first receive your the ASUS Wireless Router, if you push the reset button on the
back of the ASUS Wireless Router over 5 seconds, or if you click the “Restore”
button on the “Factory Default” page under “Advanced Setup”.
