Configuration Utility Problems

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.

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 71

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 48

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.
