2PLUGGING IN THE RSU
You can connect the RSU directly to a computer, or you can connect it to a small office/home
office (SOHO) network.
• If you are directly connecting the RSU to your computer, complete the steps in this section.
• If you are connecting the RSU to a network, refer to the section “Connecting the RSU to a
network” on page 13 in this guide.
To plug in the RSU:
1 On the side of the RSU, locate the Ethernet jack. Plug one end of the Ethernet cable into the
Ethernet jack (Figure 2).
2 Connect the RSU’s AC power cord to the power source, then plug the power cord into a wall
outlet. Plug the power source cord into the side of your RSU (Figure 2).
Figure 2: Ethernet Jack Location on Side of RSU

Note: If the RSU’s lights blink in sequence (that is, chase each other), rather than blink
simultaneously, the RSU cannot detect enough signal from your service provider to operate
properly. You must adjust the RSU so that at least one light blinks. Step 3 on page 7 describes
how to adjust the RSU.
Figure 4: Indicator lights blinking in sequence: no signal found

3FINDING THE STRONGEST SERVICE PROVIDER SIGNAL
Your RSU is equipped with an internal directional antenna. To provide the best service, the RSU
searches for the strongest signal transmitted by your service provider.
You can find the strongest signal from your service provider by using one of the following
methods:
• Indicator light method (available for any operating system)
• Software-assisted method (available for Windows operating systems only)
Regardless of the method you use, you need to understand which sides of the RSU is the back
side, which contains the antenna. The back side of the RSU is the side without a logo printed on it.
Figure 5 illustrates the RSU’s back side.
Figure 5: RSU back
8
3AUSING THE INDICATOR LIGHTS TO FIND THE STRONGEST SERVICE
PROVIDER SIGNAL
You can find the strongest service provider signal by using the lights on top of the RSU (Figure
6). You can use this method regardless of the operating system your computer runs.
The indicator lights indicate the strength of the signal received while the RSU is in its current
orientation. The stronger the signal, the more lights on the RSU blink on and off. The strongest
signal may be indicated by one or two lights lit. Even though not all five lights are lit, this level of
signal is strong enough for full-speed operation.
To use the lights to find the strongest service provider signal:
1 Before you begin, make sure:
• Your computer is turned off.
• The RSU’s power cord is connected to the RSU and to a power source. If your RSU has
power, the lights on the RSU blink on and off.
• The Ethernet cable is connected to the RSU. The other end of the Ethernet cable is not
connected to the computer.
2 Set your RSU on a table or shelf in the location you’ve chosen. The RSU must be in an
upright position.
3 Point the back of the RSU directly toward the window.
4 Remove your hands from the RSU. Keep the RSU stationary, in this orientation, for about
five seconds.
Figure 6: Location of lights on RSU
Lights on RSU
9
The blinking lights indicate the strength of the signal received. The stronger the signal, the
more lights on the RSU blink on and off. Figure 7 illustrates blinking lights.
5 Point the back of the RSU to the right of the starting position. Remove your hands from the
RSU, and let it stand still for about five seconds.
6 Again, note how many lights are blinking while the RSU is in this orientation. The stronger
the signal, the more lights on the RSU blink.
7 Point the back of the RSU to the left of the starting position. Remove your hands from the
RSU, and let it stand still for about 5 seconds. Note how many lights blink while the RSU is
in this orientation.
8 Remembering the strongest signal reported, re-orient the back of the RSU in the direction
that the RSU was pointed when the strongest signal was found.
9 Plug the Ethernet cable into your computer. The other end of the cable should already be
plugged into the RSU.
10 Turn on your computer. During power up, the lights on the RSU stop blinking, and are
continuously lit.
11 After the lights stop blinking, observe the lights for about 30 to 90 seconds. Make sure the
same number (or more) of indicator lights stay on.
• If the same number or more lights are on, you are ready to use your high-speed Internet
connection.
• If fewer lights are on, complete the fine tuning steps described in the section, “Fine-tun-
ing the connection to the service provider” on page 12.

3BUSING THE SOFTWARE-ASSISTED METHOD TO FIND THE STRONGEST
SIGNAL
Note: The software-assisted method is available only to users who use Windows (versions later
than 3.11) as their operating system.
To use the software program to help you search for the strongest service provider signal in your
area:
1 Install and start the LinkMonitor™ program.
2 Find the strongest service provider signal.
Each task is explained in greater detail in the sections that follow.
Installing and starting the LinkMonitor program
1 If your computer is not powered on, power it now.
2 Make sure the Ethernet cable and power cable are connected to the RSU.
3 Plug the other end of the Ethernet cable into your computer.
4 Locate the software CD for the RSU. If you do not have a software CD, contact you service
provider. They can provide the CD for you, or provide a location from which you can
download the software.
5 To start the installation program, double-click the Setup.exe icon.
Follow the instructions in the dialog boxes to complete the installation of the LinkMonitor
program.
6 After the software is installed, a blue RSU icon appears in your system tray (Figure 8).
To run the LinkMonitor program, right click on the icon, and select Open.
Figure 8: Starting the LinkMonitor program

7 The Expedience LinkMonitor window appears (Figure 9).
Finding the strongest service provider signal
During this procedure, point the back of the RSU directly toward an outside window. Then, point
the back of the RSU to the right of the starting position, and then to the left of the starting
position.
At these three points, briefly stop the movement of the RSU and note the strength of the signal
from your Internet service provider, as indicated by the score that the software program reports.
Before you begin, ensure your RSU is sitting on a table or shelf, in the location you’ve chosen.
1 Point the back of the RSU toward the window. Remove your hands from the RSU.
Back at your computer program, click Start Scan. Let the RSU sit stationary for about five
seconds.
2 The program searches for a signal from your service provider. In the Channel Score group,
the strength of the signal received at the starting position is indicated in two ways:
• The indicator bar shows a green bar, whose height increases in proportion to the strength
of the signal detected.
•The Current Score field shows the signal strength. During this procedure, the program
compares the Current Score to the Best Score. Best Score indicates the strongest signal
the program has ever seen during the scanning procedure.
3 After about five seconds, point the back of the RSU to the right of the starting position.
4 Remove your hands from the RSU and make sure the RSU is stationary.
The software program determines and reports the strength of the signal that the RSU
receives while the RSU is in its current orientation.
5 After about five seconds, note the strength of the signal received at its current position.
6 Point the back of the RSU to the left of the starting position.
Figure 9: Expedience LinkMonitor window
12
7 Remove your hands from the RSU and make sure the RSU is stationary.
The program determines and reports the strength of the signal that the RSU receives while
the RSU is in its current orientation.
8 Remembering the strongest signal reported, re-orient the back of the RSU in the direction
that the RSU was pointed when the strongest signal was found.
9 After about five seconds, click Stop Scan. The lights on the RSU stop blinking and become
continuously lit.
10 After the lights stop blinking, observe the lights for about 30 to 90 seconds. Make sure the
same number (or more) of indicator lights stays on.
• If the same number or more lights are on, you are ready to use your high-speed Internet
connection.
• If fewer lights are on, complete the fine tuning steps described in the section, “Fine-tun-
ing the connection to the service provider” on page 12 in this guide.
You only need to re-run the LinkMonitor program and repeat the scan when you power down
your RSU and move it.
4FINE-TUNING THE CONNECTION TO THE SERVICE PROVIDER
After performing initial setup, most users will be able to operate their RSU without further fine-
tuning.
However, if you notice fewer lights on the RSU are lit after 30 to 90 seconds of use, fine tune the
connection to the service provider. The fine-tune procedure ensures the signal received from the
service provider is strong (as indicated by the number of lights lit) and high-quality (as indicated
by the number of lights lit over time.)
1 Unplug the Ethernet cable from the computer.
2 The current position of your RSU is its starting point. Point the RSU slightly to the left of its
starting point. Note the number of indicator lights that blink.
3 Point the RSU slightly to the right of its starting point. Note the number of indicator lights
that blink.
4 Point the RSU toward the direction it was facing—either to the left or to the right of the
starting point—when the most lights were blinking.
5 Plug the Ethernet cable back into the computer.
6 Refresh your IP address by performing the procedure described in the section “Renewing the
host computer’s IP address” on page 13.
5CONNECTING TO THE INTERNET
After completing steps 1 through 4, you should be able to connect to the Internet.
1 Start your Internet browser, and try to open a few Internet sites.
• If you can open numerous sites, enjoy your new, high-speed service.
• If you cannot open any sites—for example, if your browser displays a message “This
page cannot be displayed” for all the sites you tried to access—refresh the RSU’s con-
nection, as described in the section “Renewing the host computer’s IP address” on
page 13 in this guide.
13
Renewing the host computer’s IP address
When you renew the host computer’s IP address, your service provider is assigning your
computer a new IP address by using the Dynamic Host Configuration Protocol (DHCP).
The host computer’s IP address is renewed when you restart the computer.
You need to renew your computer’s IP address if your Internet browser does not let you open
any Internet sites or if you needed to perform the fine-tuning procedure as described in the
section “Fine-tuning the connection to the service provider” on page 12.
WINDOWS USERS: RENEWING THE IP ADDRESS
The host computer’s IP address is renewed when you restart the computer. To refresh the
connection without restarting the computer:
1 Make sure you have installed the LinkMonitor program.
2 In the system tray, right click the blue RSU icon (Figure 13) and select Open.
3 In the window that appears, on the Local Net Config tab, click the Renew IP Address
button.
Note: Windows users can also go to a DOS prompt and use the command
ipconfig /renew to renew the DHCP address.
NON-WINDOWS USERS: RENEWING THE IP ADDRESS
If you do not run the Windows operating system, you can reboot your computer to refresh the
connection. You may want to refer to your operating system’s help files to determine if other
methods exist to refresh the connection (that is, to find a method for refreshing the IP address).
Connecting the RSU to a network
Note: Plan to use only one RSU on a network. Do not use multiple RSUs on the same network.
To directly connect the RSU to a computer, use the supplied Ethernet cable (also known as a
straight-through cable).
However, to connect the RSU to a hub or switch, use an Ethernet cable appropriate for your
network device. This might be a straight through or cross-over cable, depending on how your
network device switches signals. When determining how to set up your network, remember that
the RSU device operates as a hub or a bridge.
After connecting the RSU to the network device, power the RSU and scan for a service provider
signal, as described in earlier sections of this guide.
Troubleshooting
This section describes possible issues with RSU installation and how to resolve the issues if you
encounter them.
THE RSU CAN SUCCESSFULLY RECEIVE A SIGNAL AT HOME, BUT NOT AT
WORK OR AT A FRIEND’S HOUSE
You need to repeat the search for a service provider signal each time you power down your RSU
and move it.
If you have not repeated the signal search, repeat the steps described in the section “Finding the
strongest service provider signal” on page 7 in this guide.
If this does not solve the problem, check with your service provider to make sure they offer
service to the geographic location where you are running the RSU.
14
THE RSU CANNOT RECEIVE YOUR SERVICE PROVIDER’S SIGNAL
Most users can receive a signal from their service provider when they operate their RSU near an
outside window, on the first or second floor of their home or office.
However, you may need to run the signal scan in more than one location in your home or office
to get a signal.
If you performed the signal scan in two or three locations in your home or office, but did not
receive a signal, contact the electronics or computer store where you purchased the RSU, or
contact your service provider.
THE RSU’S LIGHTS BLINK IN SEQUENCE
If your RSU is unable to find a service provider signal, the lights on your RSU don’t blink
simultaneously, but rather they blink in sequence, with a light blinking on as the previous light
blinks off.
15
Figure 10 illustrates lights blinking in sequence.
If you have tried to use your RSU in several locations within your home or office—without being
able to receive a signal— contact your service provider for further information about connecting.
Figure 10: Indicator lights chasing: no signal found
16
YOU SUCCESSFULLY COMPLETED THE SIGNAL SCAN, BUT YOUR INTERNET
BROWSER CANNOT CONNECT TO A WEB SITE
If you tried to connect to only one Internet address, try to connect to a few more. It is important
to try a few different Internet addresses because the single site you were unable to reach may
indicate that the site is out of service, not that the RSU is malfunctioning.
However, if you tried to reach a few sites without success, you may need to refresh your RSU’s
connection with your service provider.
When your RSU first connects with your service provider’s equipment, your computer is assigned
an IP address. This IP address ensures that the Internet information you request can reach your
computer and your Internet browser.
If your Internet browser cannot open any sites:
1 Make sure your computer is set up to automatically receive an IP address, as described in the
section, “Setting up the computer to dynamically receive an IP address” on page 3.
2 Refresh the connection with your service provider by performing one of the following:
• If you are a Windows user, open the LinkMonitor program. Click the
Renew IP Address button.
• If you are using a non-Windows operating system, reboot your computer.
3 Try opening a few web sites with your Internet browser.
THE LIGHTS ON THE RSU BLINK MORE SLOWLY THAN NORMAL
When your RSU searches for a service provider signal, the lights on the RSU blink on and off
rapidly. If you notice the RSU’s lights blinking more slowly than usual, this usually indicates that
your RSU is trying to register with your service provider.
During registration, your service provider may be checking records to indicate that you are a valid
user of the service provider’s system. In most cases, the registration process happens so quickly
you hardly notice a change in the blink rate of the lights on your RSU.
However, if the lights blink slowly for an extended time (more than 30 seconds):
1 Force your RSU to scan for another signal by unplugging the Ethernet cable from the
computer RSU or by using the LinkMonitor application’s Start Scan button.
2 Repeat the procedure described in the section “Using the indicator lights to find the strongest
service provider signal” on page 8.
At the end of this procedure, you should have plugged the Ethernet cable back in.
3 Perform one of the following:
• If your RSU successfully registers, as indicated by continuously lit lights, you can use your
connection.
• If the lights on your RSU continue to slowly blink on and off, contact your service pro-
vider.
YOU RECEIVE A DIALOG BOX INDICATING THAT YOU CANNOT CONNECT
TO YOUR SERVICE PROVIDER
When you try to connect with your service provider, you may receive a message on your computer
indicating that you cannot connect at this time.
You may receive this message for any number of reasons, such as the service provider’s
equipment may be malfunctioning, your RSU is malfunctioning, or your service provider is still
processing your payment or identification records.
17
If you receive such a message:
1 Make a note of the message’s contents and any error number that appears.
2 Contact your service provider with this information. They should be able to resolve the
problem for you.
LINKMONITOR APPLICATION CANNOT COMMUNICATE WITH RSU WHEN
VPN IS USED
When using a virtual private network (VPN), you may receive a message indicating that the
LinkMonitor application cannot communicate with the RSU. Some configurations of VPN
prevent communication between the application and the RSU.
To successfully use the LinkMonitor application, disconnect from the VPN.
RSU MALFUNCTIONS AFTER YOU WRITE ON THE RSU OR ATTACH
STICKERS TO THE RSU
Do not write on the RSU or attach stickers to the RSU. Doing so may interfere with the Internet
signal, causing your RSU to malfunction.
