Average Reviews:
(More customer reviews)I bought a pair of HDXB101 boxes in the hope that they might offer a reliable replacement for the 802.11g boxes I'm currently using. Boy was I disappointed.I live in a recently refurbished apartment, with all new electrical wiring. In principle, this should offer an optimal environment for powerline networking.
While setup was as easy as the box claimed - it was literally a matter of plugging the two boxes into the wall, and everything worked immediately - it quickly became clear that the performance was not going to work out.
A quick word of caution before I continue: please read most of the positive reviews of this device, and notice that they are doing very unchallenging things, like streaming music. Music streaming is extremely tolerant of both poor bandwidth (bytes per second) and high latency (time it takes data to get from A to B). If all you want to do is stream MP3s and browse the web, this hardware is perfectly decent.
However, for even the most slightly challenging application, the performance is horrifying. I measured the latency between my two HDXB101 boxes, and it was consistently atrocious, even when the two were plugged into two sockets of a paired wallmount.
To give you an idea of "atrocious", my 802.11g network consistently gives a latency of 1.2 milliseconds. My gigabit ethernet network is more like 0.1 milliseconds. The *best* number I got out of the Netgear hardware was 3.5 milliseconds, and the *average* was 55 milliseconds. Holy cow! That means my bedroom and living room are as far apart, in terms of latency, as California and Germany! This is an amazingly bad number.
But what's much worse is that the number is extremely jittery. There were constant stalls of up to one second in duration, with delays of 150 milliseconds or more happening several times a second. This is the sort of thing you won't notice at all if you're playing music or viewing web pages, but it makes gaming incredibly frustrating.
The unpredictable latency has a strong negative effect on bandwidth, too.The box advertises 200 megabits per second. At no time have I measured more than 3.3 megabits per second, slightly over 1.5% of the advertised peak performance. This isn't even enough to saturate my DSL line, and is perhaps 50% slower than my wireless network. Needless to say, there's no way you're going to stream anything more than Youtube-quality video (i.e. really cheesy low bitrate) over a link like this.
In case you're interested in tinkering with configuration options to improve performance, forget about it: there are no tunable options to tweak.
In summary, the bandwidth and latency on this hardware are just shockingly bad. Unless you live in a house with lead-lined rooms and have literally no other option for getting a network signal from one place to another, you should avoid this hardware like the plague.
