7.3 Configuration Utility Problems
V The PLA-4xx Series Configuration Utility displays an error during installation.
Make sure your computer is using Windows XP or Windows Vista (32-bit) operating
system. At the time of writing, this is the only compatible operating system for the
configuration utility.
V The PLA-4xx Series Configuration Utility does not display all or any of my
devices.
Inspect the LEDs on your PLA-4xx and make sure that the ETHERNET and HomePlug
LEDs are on or blinking. See Section 7.2 on page 68 for troubleshooting LED related
problems.
Check all ZyxEL HomePlug AV devices on your network have the latest firmware
installed. The latest utility cannot communicate with PLA-4xxs using earlier versions of
the firmware. Go to Section 5.4 on page 46 for instructions on installing the latest
firmware.
Check you are using the latest version utility. Earlier version utilities cannot communicate
with PLA-4xxs using the latest firmware. If you do not have the latest utility, download it
from the ZyXEL website.
If the device is not a ZyXEL device, then the DAK and Network Name will be greyed out.
If you are running another tool such as the Firmware Detection Tool or Firmware
Upgrade Tool, the Utility will not detect your local device.
7.4 Powerline Problems
V The signal on my powerline network is weak.
1 Your powerline adapters may be connected to electrical surge protectors. Connect them
to standard power outlets.
2 Your powerline adapters may be located close to large appliances such as refrigerators or
air-conditioners that cause interference with the powerline signal. Move the adapters
further away from such appliances to reduce interference.
3 Your powerline adapters may be placed close to electrical devices such as electrical
insect-killers which produce radio waves. These may interfere with the powerline
signals. Move the adapters further away from such electrical devices.
4 Your wiring may be old and/or low quality or with a long wiring path.
