Appendix A:Troubleshooting
This section provides possible solutions to problems regarding the installation
and operation of the PowerLine USB Adapter. Read the description below to
solve your problems. If you can’t find an answer here, check the Linksys web-
site at www.linksys.com.
1. None of the LEDs light up after I installed the PowerLine USB Adapter.
• Unplug the USB cable from the computer. Unplug the PowerLine USB
Adapter from the power outlet. Then repeat the hardware installation
process. Make sure the power outlet is working properly.
2. I can’t connect to other computers on my powerline network or to the Internet.
• Make sure the IP address and TCP/IP protocol are set up correctly for all
the powerline networked computers. For more information on IP
addresses, see Appendix C: IP Addressing.
• Make sure all devices on the powerline network have been configured
using the Security Configuration Utility. The network password must be
the same for all devices in order for them to communicate with each
other. See Chapter 7: Using the PowerLine Configuration Utility.
Does the PowerLine USB Adapter cause interference with other home networking
or powerline products?
No. The PowerLine USB Adapter can co-exist with phoneline and wireless net-
working technologies. Instant PowerLine operates in a different frequency band
than powerline control and can co-exist with technologies such as X-10,
CEBus, and LONworks.
How does the PowerLine USB Adapter handle signal interference between two
adjacent homes? How is eavesdropping prevented?
The PowerLine USB Adapter uses 56-bit DES security encryption to ensure
network separation between homes. To enable 56-bit DES security encryption
on Instant PowerLine products, you must run the PowerLine Configuration
Utility on each and every Instant PowerLine product.
