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.
