Can anyone speak to the robustness of Powerline Adapters? I've been testing a set of these (Linksys PLTE200 and PLTS200) on my home network for a couple of days and they seem to work pretty well.

I tried them at a client's site, and they did not work so well there  (but I was not surpised at this).

My home network - going through the same power box, but on different circuits. All works well.

My client's network - different power boxes. The weird thing about this was that at my clkinet's site, the link lights showed a good connection, but I could not ping or connect to any network eqpt on the other end of the circuit.  

My questions - any experience with these over the long haul?

And on a technical note, it does not look like these devices get an IP address (at least I can not tell that they do through the management console/utility). They do have mac addresses (2 on each unit??) - does the fact that they do not have an IP address mean that they are working as network bridges?

Another question - these Linksys Powerlines come in 2 flavors, an 85 MB/s and a 200 MB/s (max) model. The latter is marketed specifically as an AV transport/delivery system. They are the same price. What gives with that? One reviewer mentioned that they had great luck with the 200MB model and no luck with the 85 MB model - at any speeds. But I did not see many commenters discussing this. . . . The 200MB/s version has 128 bit encryption compared to the 85MB/s version w/ 64 bit. It also seems that setting the encryption keys is more error-prone on the 200 MB/s vers.

What about compatibility? Can the 85MB/s and 200MB/s models be mixed on a single network? Is the 85MB model desirable because of compatibility w/ other vendor's Powerline systems?

Any expert information and experience with this would be appreciated.
