This product is based on a "HomePlug-AV" chipset than runs a specialized type of sofware known as "firmware". Linksys does not design, manufacture, or maintain this chipset or its firmware. An unaffiliated company does that, and Linksys is just one of dozens of that company's customers.
I've purchased about 20 (twenty) PLE200s over the past year--from Amazon and other sellers--and all of them have shipped with firmware version 1.4.5 installed. The primary purpose of my 'review' here is to caution you that hardware running firmware version 1.4.5 cannot communicate with hardware running newer firmware versions. I hope this caution reaches people who have already purchased the PLE200 as well as those who are contemplating doing it.
Version 2.0 implemented a change that was required to achieve compliance with the HomePlug-AV standard. That change unfortunately rendered 1.4.5 unable to intercommunicate with versions thereafter. Fortunately, no subsequent firmware change will have such a devastating side-effect.
"HomePlug-AV" products currently coming off various manufacturers' production lines are likely shipping with 2.0 or later firmware installed. Be advised that if you wish to build unified network consisting of PLE200s and these other products, you'll have to upgrade the firmware in your PLE200s; otherwise, the PLE200s and the other products won't even "see" each other. Not only that, but they'll probably also step on each other's transmissions because of inability to coordinate their usage of the powerline medium.
The PLE200 ostensibly is compliant with the HomePlug-AV standard, but it actually is NOT compliant with the HomePlug-AV standard until its firmware is upgraded from version 1.4.5 to version 2.0 or newer. As of this writing, 3.0.5 is the newest version.
Linksys ought to provide a binary image of the firmware for download on their web site, but I don't see it. The Windows GUI application that Linksys ships on CD with the PLE200--it has a mechanism for programming a new firmware image into a PLE200, but I've never used it and am not certain it is able to perform the 1.4.5-to-later upgrade even if it were given the appropriate binary image.
Being an engineer who is doing development work in the HomePlug-AV space, I have the means to do the upgrade, but it requires my using some software that is not available to the general public. To the general public who already own PLE200's, I would suggest pestering either Linksys or the chipset manufacturer about the firmware. To everyone else--maybe you can find a HomePlug-AV adapter under a different brand name that comes with firmware version 2.0 or later pre-installed.
