Q4 
Do older electrical wirings affect the powerline
devices? |
|
| In
some cases, old wiring may have faulty connections
or have long wiring paths that may influence
performance. |
|
|
|
| Q5
If I plugged the USB adapter into the USB
port and it doesn・t work, what do I
do? |
|
Make sure you have installed the USB driver
from the installation CD. |
|
 |
|
| Q6 When
trying to install the USB driver in Windows
98, there is an error message saying that
some file is missing |
|
A file
newdev.dll is needed for the installation
of the USB driver in Windows 98. you can download
this file from http://www.dlldump.com/cgi-bin/dlldownload.cgi?path=dllfiles/N
Search for the file newdev.dll and install
this file into the
windows/system directory. The installation
should work after restarting your computer.
|
|
|
|
| Q7
When trying to install
the USB adapter in a WinXP machine, the PC
reboots automatically after the installation
with no error messages. Once the PC is rebooted,
an error message appears: ：Windows cannot
load the device driver for this hardware.
The driver may be corrupted or missing. (Code
39)； |
|
| A solution
for this problem is to first uninstall the
driver and click Scan for hardware changes.
You will be prompt to reinstall or upgrade
the driver. You can then reinstall the driver
from the installation CD. |
|
|
|
| Q8
Can the USB adapter run under Linux?
|
|
| Adapters
with older Intellon chipset version (A1) run
under Linux. You can find a driver for it
in Linux kernels from version 2.4.19 higher.The
new Intellon chipset versions (51X1 and 5200)
are not supported under Linux for the moment.

|
|
| Q9
What is the range in distance for the powerline
devices? |
|
| Exceeding
a distance of 300 meters, our powerline devices
can assure a bandwidth of 500 k (worst case).
|
|
|
|
| Q10
Are the powerline communications secured?
|
|
| Yes,
the powerline communications are secured with
56-bit, DES encryption to secure the data
during transmission. |
|
|
|
| Q11
Is powerline a shared
communication medium? |
|
| Yes,
all the powerline devices connected to the
network share the available bandwidth. |
|
|
|
| Q12
Do the powerline devices work on MAC computers?
|
|
| Yes,
only the Ethernet powerline devices will work
for MAC computers, as long as they don・t need
a driver. |
|
|
|
| Q13
Is powerline more secure
than wireless? |
|
| In
a powerline network, an intruder has to be
physically connected to an outlet in the circuit
to be able to ：steal； information. On the
other hand, wireless signals can be intercepted
：in the air； within a range of the antenna. |
|
|
|
| Q14
What can I do to make
sure that the highest performance of the powerline
devices are attained? |
|
•Do
not plug the devices into power strips or
electrical surge protectors, as they may attenuate
powerline signals.
• Place the
powerline devices away from high consumption
appliances.
• Make sure all devices
are placed on the same electrical circuit,
same circuit panel and on the same phases.
Electricians can help with identifying these.
|
|
|
|
| Q15
Will the powerline signal pass between houses?
|
|
| The
powerline signals do not pass power meters,
thus signals should not be able to pass to
other houses. However in some cases, depending
on the path and the length pf the wiring,
it can happen. Powerline uses 56-DES encryption,
so even if the signals pass to the houses
nearby, the encryption will secure your data. |
|
|
|
| Q16
Will the powerline signal pass through power
transformers? |
|
| The
powerline signals will not pass through these
transformers. |
|
|
|
| Q17
Do the devices have protection against power
surges if the use of surge protectors is not
recommended? |
|
| Yes,
the powerline devices have internal surge
protectors that provide protection against
power surges. |
|
|
|
| Q18
Will the powerline signals pass through different
phases? Would a phase coupler help? |
|
| In some
cases, the powerline signal will be able to
pass through a different phase because of
mutual inductance. However, testing has shown
that the strength of the signals is very weak
and eventually the performance goes down,
until the communication is completely lost.
A phase coupler is an ideal solution to this
problem; installed in the power distribution
box by an electrician, the phase coupler joints
all phases together allowing signals to be
injected directly into the different phases.
|
|
|
|
| Q19Will
powerline signals go up and down to other
floors in a house? |
|
| Yes.
As long as there are electrical wirings running
and anywhere where there are electrical outlets,
you will be able to connect. Unlike the wireless
technology, powerline signals can go up and
down floors without a problem. |
|
|
|
| Q20
Will
there be possible frequency interferences
using powerline? |
|
| The
powerline technology uses a different section
of frequency than other appliances, so interferences,
if any, are rare and little. On the other
hand, wireless technologies share the frequency
with Bluetooth, cordless phones, and many
other wireless appliances. |
|
|
|
| Q21Will
plugging the powerline device into the power
socket blow a fuse in the house? |
|
| No.
A fuse will blow if you are having too many
appliances on a single circuit of the house.
|
|
|
|
| Q22Will
other household appliances affect the performance
of the powerline devices? |
|
| The
powerline devices have powerful error correction
and can work in very harsh environment. Though
the performance could slightly be reduced,
it can keep a continuous data transmission.
|
|
|
|
| Q23I
have successfully installed a few adapters
but when I run the utility, they cannot see
each other. |
|
| Please
make sure that all the devices have the same
default password: HomePlug. If not, please
reset all the devices to their default password
and make sure they are the same. |
|
|
|
| Q24The
utility software cannot recognize the powerline
device. |
|
| Try
resetting the device by unplugging the power
and plugging it again. It is also a good idea
to restart your PC. |
|
|
|
| Q25Can
powerline devices manufactured by two different
companies communicate with each other? |
|
The powerline technology is based on the HomePlug
standard, so as long as the devices are based
on the same standard, they will be able to
communicate with each other |
|
|
|
| Q26Are
there any limits to the number of powerline
units that can operate in a LAN? |
|
| The
ideal is to keep the number of computers equal
to or under 16 (altogether they will share
a bandwidth of 14 Mbps). All additional computers
after the 16th will share a bandwidth of 1
Mbps. |
|
|
|
| Q27I・ve
changed the NEK of a device remotely following
instructions of the manual, but the NEK does
not seem to be changed. |
|
| Because
of security reasons (in a network administrator・s
point of view), the remote device will not
be able to see its new password. Only the
computer that has changed the password of
the remote devices will have a list of all
the NEKs set. |
|
|
|
|
•When you remove a powerline device
or disconnect the cables, all other powerline
devices need about 5 minutes to refresh their
memory about the current status of the device.
• To check if a house・s electrical
wiring is causing the powerline problems,
try plugging the units in the same room first.
Old fuse boxes and old wiring could affect
performance.
• Change the
devices to isolate the problem to a particular
powerline unit. |
