I've been using the Netgear XE102 14 Mbps powerline modules for awhile,
and they work fine around the house.

I noticed there appears to be TWO different Netgear listings
for the 85 Mbps powerline modules...

http://www.netgear.com/Products/PowerlineNetworking/PowerlineEthernetAdapters/XE103.aspx
and
http://www.netgear.com/Products/PowerlineNetworking/PowerlineEthernetAdapters/XEt1001.aspx

In looking at the data sheets,
I can't see any difference....

SO - why are there TWO different models ?
What is the subtle difference I'm missing ?

Well, the web page for the XET1001 specifically mentions HomePlug
compatibility and data encryption.

price? one is white and one is tan? One has a bigger number than the
other?....

odd, they even work with each other too

Have you tried finding the FCC ID No's and then checking the info on the
FCC website?
It may be just a change of chipset. Atheros bought out Intellon so there
may be a slight change in chipset design.

Not content with using up to 30MHz for powerline working the latest chip
from Atheros supports operation up to 75MHz.
"The AR7400 Chipset
The Atheros Powerline chipset consists of the AR7400 MAC/PHY transceiver
and the AR1500 analog front end (AFE) / line driver. The AR7400 chipset
is the world�s first solution designed to comply to the IEEE 1901 draft
2.0 standard (now elevated to Sponsor Letter Ballot status), a global,
open powerline standard. Just as the IEEE 802.11 standard unified and
accelerated the growth of the wireless LAN industry, the IEEE 1901
standard will help to unify and drive the expansion of the powerline
networking industry. The 1901 standard utilizes a wider operating
frequency band (2 MHz to 50 MHz) than the current HomePlug AV standard
(2MHz to 30 MHz), thereby increasing PHY performance in IEEE 1901
operation. The AR7400 chipset will comply with the FFT-OFDM provision of
1901 and incorporates the inter-PHY protocol (IPP) co-existence mechanism.

The chipset also supports operation up to 75 MHz, utilizing all of the
practically available spectrum defined in the 100 MHz IEEE 1901 charter,
and avoiding the global, high-power FM radio broadcast bands from 76 to
108MHz. This extended frequency range coupled with high density
modulation to 4096 QAM, allow AR7400-based powerline products to
communicate at more than 500 Mbps PHY rates. In coaxial cable
applications, the PHY rates can exceed 600 Mbps, while providing
extended coverage due to the AR1500�s lower noise floor and greater
output dynamic range. "
