The User Guide references a PLA Series Configuration Utility. But there is no CD in the box that contained only documentation and the utility wasn't found via Support searches for either PLA5405 or PLA Series Configuration Utility.

My experience has shown these utilities are of little use anyway. I've yet to find a powerline device that had any updated firmware to be installed. And the QoS configuration screens are not user friendly and have no useful documentation.

The only possible use is to check link rate, which again, I rarely find provides an accurate reflection of the actual throughput of a powerline connection.


I tested the PLA5405 using our standard powerline test procedure, with all results entered into the Powerline Performance Charts.

Since this is the only AV2-M1000 class device, I took the approach of comparing it to three products closest to it in the Powerline Charts, ZyXEL's PLA5206 (AV2-S750), TP-LINK's TL-PA6010 (AV2-S500) and ZyXEL's PLA5205 (AV2-S500).

The Downlink Throughput plot below clearly shows the PLA5405 having the highest throughput only in the best-case same-outlet Location A. The 5405's 333 Mbps is 25% higher than the next-best TP-LINK TL-PA6010 with 267 Mbps. But the plots show the 5405's advantage doesn't carry into the medium-range location C test, where it is beaten by the TP-LINK. And in worst-case Location E, all but the AV2-S500 class PLA5205 are about the same between 102 and 108 Mbps.

Uplink results show a similar pattern. The 5405 is best in Location A with 351 Mbps, but drops to next-to-last position in Location C and runs with the most of the pack in Location E.

The simultaneous up /downlink IxChariot plot for the PLA5405 shows uplink favored over downlink by almost 2 to 1. But there is cyclical variation and the two streams appear to be slowly converging. Note throughput totals almost 420 Mbps!
