Configuration Utility Problems

The PLA42xx 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.

The PLA42xx Series Configuration Utility does not display all or any of my devices.

•

Inspect the LEDs on your PLA4215 and make sure that the ETHERNET and HomePlug LEDs are on

or blinking. See

Section 6.1 on page 47

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 PLA4215s using earlier versions of the firmware. Go to

Section 4.4 on page 29

for instructions on installing the latest firmware.

•

Check you are using the latest version utility. Earlier version utilities cannot communicate with

PLA4215s 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

, the Utility will not detect

your local device.

Powerline Problems

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.
