Network Terms  
What is a node?  
A node is any given device that resides or is connected onto an existing network. A computer with a  
network card connected to a switch is a node. The same thing applies to a Mac connected to a hub.  
What is a bridge?  
A bridge is used when connecting one side of the network with another network. Previously, connecting  
every computer together with the other network would mean having cables all over the place. Instead a  
bridge was brought in to have 1 connection between the networks instead of 20. The bridge in the  
HomePlug terms functions like a concentration device that connects many computers onto the  
HomePlug network using 1 HomePlug device.  
How do I know if I require a node or a Bridge?  
If you want to connect only one computer to the Powerline network, you need a node. If you plan to  
connect a group of computers currently not HomePlug ready to the Powerline network, you need a  
bridge. The HomePlug to USB adapter can only be used as a node. The HomePlug Ethernet bridge can  
be used as either a node or bridge. It is designed as a bridge by default; the only way to turn it off is to  
install the utility software that comes with the unit. That will turn the bridge into a node. If used as bridge,  
27

Networking Configuration  
there is a limitation of having only two bridges on the same Powerline network.  
You will have to use bridges to connect two Macintoshes, because the utility software is not compatible  
with Windows based computers.  
Can I use both in the same network?  
Yes. It is possible to have both nodes and bridges on a network as long as there is only a maximum of 2  
bridges. It is also fine to have USB nodes on the same network with Ethernet nodes.  
How do I decide whether I need a USB adapter or Ethernet bridge as a node?  
It should be determined by the available connection on the computer that you plan to connect to  
HomePlug network. If the computer comes with a 10/100 NIC card, use the bridge; if the computer  
comes with a USB port, use the USB adapter. If the computer comes with both, you can decide based  
upon your unique situation.  
For Macintosh and other non-Windows based computers, a bridge is the only choice.  
HomePlug Network Topologies:  
There are various ways to connect your computers via HomePlug. If all HomePlug units are used as nodes,  
the topology is usually BUS. If bridges are used to connect two networks together, there maybe both BUS  
and STAR. Following are several examples.

Sharing Internet Access  
Topic 6. Sharing Internet Access  
So how can the Internet connection be shared among other computers on the HomePlug  
network?  
Since neither the HomePlug Bridge nor USB adapter are capable of routing at this time, a  
router is necessary in order to share the Internet connection. Future versions of the  
HomePlug Bridge or USB adapter may feature built-in routing capabilities.  
The following items are required for successfully sharing the Internet connection:  
• One (1) Router  
• One (1) HomePlug Bridge  
• One (1) DSL/Cable Modem  
• Active ISP Service for the DSL/Cable Modem  
• CAT5 Cables  
63  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Sharing Internet Access  
• Also all computers that share the Internet connection must be connected to a HomePlug  
USB Adapter or a HomePlug Ethernet Bridge.  
Please note that only two (2) HomePlug Bridges are allowed on one network if used as  
bridges (without installation of the software).  
Please follow these steps for setting up Internet Sharing:  
64  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Sharing Internet Access  
a. Make sure that the DSL/Cable modem is connected to the Router (using the WAN port  
on the router.)  
b. Connect the HomePlug Bridge to the Router (using the Uplink port on the router.)  
c. Check the link light on the HomePlug Bridge. It must light up green.  
IMPORTANT:  
The HomePlug Bridge MUST connect to the "Uplink" port on the router.  
d. Make sure that the computers that need access to the Internet via the HomePlug  
network are each connected to a HomePlug Adapter or a HomePlug Bridge and reside  
on the same power grid.

Sharing Internet Access  
Checking Router Settings:  
Please assure that the following settings on your router are set:  
(The setup windows will depend on the router manufacturer's software.)  
A)TheIPshouldbeobtainedautomatically;  
B) DHCP must be enabled;  
C) Release DHCP and then Renew DHCP to reset the IP Addresses. It is recom-  
mended that you verify that IP Addresses are obtained.  
Once all the above steps have been completed, all HomePlug connected computers will  
be able to access the Internet.

Troubleshooting  
Frequently Asked Questions/Troubleshooting  
1. Will HomePlug work in my house or apartment?  
If the house or apartment was built under U.S. building standards using copper wiring, then  
it will work.  
2. What types of security problems will I be facing?  
If your house is on the same power grid as your neighbor, then there is a potential for a  
hacker to get in through your neighbor's house. However, this is easily remedied by  
activating the encryption key on the HomePlug device.  
3. Will HomePlug work with Mac?  
There is currently no software that supports Macs. However, the HomePlug Ethernet Bridge  
will work with Mac when used as a bridge. Also, by installing Virtue PC software on a Mac,  
you will be able to install the windows based software under Virtue PC and have this Mac  
communicate with other PCs on HomePlug network.

Troubleshooting  
4. What is the difference between bridge mode and node mode in the HomePlug Ethernet  
Bridge (GHPB01)?  
Bridge mode operates without software installation and can work with any 10/100Base-T or  
10Base-T Ethernet connections. By connecting the bridge to a router, switch, or Ethernet  
based device (XBOX, PlayStation, Web Tablet, PocketPC, Computer, etc.), you will be able to  
make these devices bridge onto the HomePlug network. Currently, the GHPB01 only supports  
2 bridges per HomePlug Network.  
Node mode operates by connecting the HomePlug USB adapter (GHPU01) or Ethernet  
bridge (GHPB01) to one computer (ONLY) and installing drivers onto the computer, allowing it  
to set the device into Node Mode. The advantage with Node Mode operation is there is no  
limitation to the number of nodes that can operate on a HomePlug network.  
5. Why do I get a blue screen on boot-up after installation under Windows 98?

Troubleshooting  
problem, go into Windows Safe Mode and disable the Virtual Private Networking Adapter.  
You can disable the Adapter by right clicking on your Network Neighborhood Icon and  
clicking on properties. This will list all adapters installed on your computer. Right click  
and select disable on the adapter labeled Virtual Private Networking. This will allow  
Bridgedecor.exe to startup correctly on boot.  
6. Will HomePlug operate on different Circuit Breakers?  
Yes. Circuit breakers do not affect performance of HomePlug devices, however the signal  
will not pass through the power transformers outside your house.  
7. Can Neighbors get my HomePlug signal?  
It is possible for your immediate (next door) neighbor to receive residual signal from  
your HomePlug adapter. Unlikely, but possible. To prevent your neighbors from hacking  
your network, the best thing you can do is type a different encryption password into  
your device when setting the encryption password. Note: All devices must have the  
same password to be on one network. If devices do not have the same encryption  
password, they will not be able to communicate with each other.

8. What OS does the HomePlug utility software fully support?  
Windows 98SE, ME, XP, and 2000. Windows NT and Mac are only supported by the  
HomePlug Ethernet Bridge (Without installing the HomePlug software with default oper-  
ating mode as BRIDGE, not NODE)  
9. What is the Range of HomePlug?  
Approximately 990 feet (300 meters) in wall power lines.  
10. How does 56bit-DES compare with Wireless 802.11b 128bit-WEP encryption?  
56bit-DES is superior because of its DES type Encryption. Just because 802.11B uses  
128bit-WEP with more bits doesn't mean the encryption is better. Also, the IOGEAR  
HomePlug devices use hardware 56bit-DES encryption. With hardware encryption the  
signal is almost impossible to crack. The hardware encryption process does not affect  
bandwidth, and the encryption is enabled at all times.
