Going to Amazon to check buyer's comments on this product you can see
why I've been recommending that people go with the netgear 102 or 103
(104 is same) and NOT with 101s. There are good reviews, but the bad
ones are telling in this case:

Quote:

I attempted to upgrade my electric wiring based network from Netgear
XE104's (rated at 85Mbps) to the Netgear HDX101's (rated at 200Mbps).
The performance of the HDX101 network was substantially slower and
less reliable than the XE104 network with exactly the same devices
attached to the XE104's and the HDX101's. I did not have both networks
operating at the same time even though a HDX101 network supposedly can
co-exist with a XE104 network. I highly recommend the Netgear XE104,
but was very disappointed in the HDX101. I would not even recommend
the HDX101 for use on the same electrical circuit in the same room.
The HDX101 also becomes very warm in operation.

Beware: HDX[b]101 doesn't follow the HomePlug-AV standard.....
It follows a demonstrably inferior, European-brewed standard. Netgear
simply jumped the gun and didn't wait for HomePlug-AV chipsets to
become available. This HDX[b]101 product is a dead end, because
HomePlug-AV will win the standards war.

If you truly need higher speed than is attainable from HomePlug-Turbo
products such as Netgear's XE104 (85Mbits/s best-case raw channel
bitrate), then wait a little while for HomePlug-AV-compliant ("200Mb/
s") products to hit the market in the USA....

Comment: that's an old post - HomePlug-AV is now availible, I believe.

Here's an comment that may actually help with what you now have:

One thing that we noticed though was the transfer speeds still weren't
that great. After some playing, a friend we stick a switch between the
router (linksys) and the powerline ethernet adapter, and that did it -
transfer speeds went through the roof (at the advertised
speeds)............ I recommend buying a cheap switch (got mine for
$10) and inserting that between the router and the "main" powerline
adapter and you'll be pleased.
