Common Problems and Solutions
1. None of the LEDs light up after I installed the HomePlug Ethernet Bridge.
• Unplug the product from computer and AC outlet then re-plug it again. Make sure the AC
outlet is working properly.
2. I can't connect to other computers in the PLI-2021 network or to the Internet.
• Make sure the IP address and TCP/IP protocol are set up correctly for all the power line
networked computers.

FAQ
Q: Does the HomePlug Ethernet Bridge cause interference with other home networking
or Power line products?
A: No. The HomePlug Ethernet Bridge can co-exist with phone line and wireless networking technologies.
Instant Power Line operates in a different frequency band than PowerLine control and can co-exist with other
technologies.
Q: How does the HomePlug Ethernet Bridge handle signal interference between two adjacent homes? How is
eavesdropping prevented?
A: The HomePlug Ethernet Bridge 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.
