The following list, which is not exhaustive, illustrates the standards supported in the PLA450.
Wireless Functionality Allows IEEE 802.11b and/or IEEE 802.11g wireless clients to connect to
the PLA450 wirelessly. IEEE 802.11g clients can connect using the
super G function. Enable wireless security (WEP, WPA(2), WPA(2)-
PSK) and/or MAC filtering to protect your wireless network.
Note: The PLA450 may be prone to RF (Radio Frequency)
interference from other 2.4 GHz devices such as
microwave ovens, wireless phones, Bluetooth
enabled devices, and other wireless LANs.
WPA(2)-PSK WPA-PSK and WPA2-PSK allow you to implement the WPA and WPA2
encryption standards without using a RADIUS server. Instead, WPA(2)-
PSK uses Pre-Shared Keys (PSKs) to authenticate devices on the
wireless network. WPA-PSK and WPA2-PSK provide superior security
to WEP.
Powerline Functionality The HomePlug AV standard specifies how network devices
communicate using standard electrical wiring.
It supports a data transfer rate of up to 200Mbps.
Data is encrypted using 128-bit AES (Advanced Encryption Standard).
HomePlug AV compatible devices co-exist with HomePlug 1.0 devices
but do not detect each other.
The range of a HomePlug AV network is 300 meters/984 feet in optimal
conditions.
HomePlug AV is compatible with all OSs
The maximum number of devices connected to a single adapter is 64.
Maximum number of powerline adapters on a single network is 64.
The maximum number of powerline networks on a single electrical circuit
is 4.
HomePlug AV devices using the latest version firmware cannot
communicate with earlier version firmware.
Firmware Upgrade Download new firmware (when available) from the ZyXEL web site and
use the web configurator, an FTP or a TFTP tool to put it on the PLA450.
Note: Only upload firmware for your specific model!
Configuration Backup &
Restoration
Make a copy of the PLA450’s configuration and put it back on the
PLA450 later if you decide you want to revert back to an earlier
configuration.
Time and Date Get the current time and date from an external server when you turn on
your PLA450. You can also set the time manually. These dates and
times are then used in logs.
Logging and Tracing Use packet tracing and logs for troubleshooting. You can send logs from
the PLA450 to an external UNIX syslog server.
