Troubleshooting Scenarios
Use the following scenarios to solve problems:
Scenario 1
I can not make a connection between my computer(s), or to the Internet.
1If the ccess Point is in one of the special modes, wait for approximately one
minute to allow the ccess Point to return to normal operation. Perform a reset
if the ccess Point does not automatically return from a special mode to normal
operation within approximately one minute.
2Make sure you have set the right values for the following USB Wireless L N
parameters on your wireless computers:
•Network Name: Enter the ccess Point ID
•Encryption Key: Enter the last 5 digits of the ccess Point ID.
NOTE Note: The Access Point and all USB Wireless LANs in the wireless network must have
the same Encryption Key in order for the devices to transmit and receive readable
data. This means that if you changed the Encryption Key with the RG Setup Utility,
you have to update the Encryption Key in the USB Wireless LAN settings on every
wireless PCs in your network.
3Use the ccess Point LED table or the ccess Point Troubleshooting table to find
the problem.
Scenario 2
My network worked fine, but after running the RG Setup utility I can not make a
connection between my computer(s), or to the Internet.
1Make sure to set the right value for the ccess Point ID in the RG Setup utility.
2The ccess Point and all USB Wireless L Ns in your wireless network, must have
the same Encryption Key in order for the devices to transmit and receive
readable data. This means that if you changed the Encryption Key for the ccess
Point in the RG Setup utility, you have to update the Encryption Key on every
wireless computer in your network.
3Use the ccess Point LEDs and the ccess Point Troubleshooting table to find
the problem.

Scenario 3
I changed the Encryption Key of my Wireless L N ccess Point with the RG Set-up
utility. Now I want to update the Encryption Key on my wireless computers, but have
forgotten the 5 character Encryption Key code.
1If you change the Encryption Key on the ccess Point, you have to update the
Encryption Key on every wireless computer in your network.The ccess Point
and all wireless computers in your network, must have the same Encryption Key
in order for the devices to transmit and receive readable data.
2If you change the Encryption Key, you are advised to write it down and keep it in
a safe place. If you forget the key, you will not be able to update the Encryption
Key in the USB Wireless L N settings on your wireless computers. s a result of
that you will also not be able to change the ccess Point Encryption Key with the
setup utility.
3There is no other way to solve the problem than to perform a 'reload' on the
ccess Point. The reload will change the Encryption Key to the default value.
4fter the reload you can run the ccess Point RG Set-up utility again, and change
the default Encryption Key to a new value. Do not forget to update the
Encryption Key in the USB Wireless L N settings on your wireless computers.

Radio Specifications
NOTE The range values provide a rule of thumb and may vary according to the actual
conditions at the location where the product will be installed. The range of the
wireless signal is related to Transmit Rate of the wireless communication. The range
of your wireless devices can be affected when the antennae are placed near metal
surfaces and solid high-density materials. Range is also impacted due to “obstacles”
in the signal path of the radio that may either absorb or reflect the radio signal.
