I put one up I use with a WiFi repeater and I can see dozens of
wirless routers in my neighborhood. The antena i mounted at about
20ft on my chimney. There are about 8 or 9 with no security. If I so
chose I would never have to pay for internet service. There is another
subdivsion behind my house I havent even looked at that one yet.

If stealing internet service from the neighbors is your intended
purpose, you selected the wrong type of antenna. A sector antenna may
be a great idea for running a WISP or central access point, where
you're never sure of the direction the client radios are coming from.
It's a bad idea for use at the client end. The idea is to pickup as
little interference as possible. You're reception of 9 stations is a
problem as any one of these could provide sufficient interference to
make your pirated internet connection useless. I suggest you look
into a panel or dish antenna, which will provide a much narrower
horizontal beamwidth, with the added bonus of more antenna gain.

Strange thing I know 3 of the people who have the open systems and
they are farly savy about these things. I wonder if they are leaving
them open on purpose.

I was running an open access point at my office for a while. However,
I was also monitoring connection attempts and traffic. I figured that
nobody would bother. Wrong. I had some bum in a pickup truck and
camper, connect regularly to make VoIP phone calls. I had no problem
with him using the system and we eventually came to an arrangement.
However, he stupidly told all his friends, who immediately abused the
system, so I locked it up with a WPA password.

In another incident, one of my customers was in a hotel that wanted
real money to use their Wi-Fi. (This was about 6 years ago, before
the widespread proliferation of free Wi-Fi service). So, he connected
to a random open access point. The security on his laptop was more
than a little lacking (writable shared folders), resulting in the
installation of multiple trojan horses, spam bots, etc. I suspect the
open access point was an intentional trap set for hotel visitors.

Perhaps they want to take the blame for everyone downloading bootleg porn,
music and movies until their ISP terminates or throttles them for abuse.
Either that or they are trying to log mac addresses of those who do.


Just noticed I spelled that wrong, "honeypot" ...

Yes, well, I take it for granted, anyone able to set up and run a

My home system is "1540 Jackson Ave" which is my address. The

I'll stand by my statement. Unless you're running a mesh network, an
omni at the client end is a bad idea. The client knows the direction
of the desired access point and should use a directional antenna to
minimize interference. In my limited experience (I ran a small WISP
and neighborhood LAN/WLAN for a few years) interference is the most
serious impediment to reliable operation. The more you can do to NOT
hear the undesired stations, the more reliable the connection.

You can
"bridge" multiple access points for better throughput ...

Sorta. You can do route switching easily enough, but load balancing
between multiple internet connections can't be done without IP
bonding, which requires everyone's cooperation (including the ISP's).
The problem is that you can't use multiple ISP's to improve the
download speed from a single connection. For example, if you want to
download a large file, it will only go as fast as the speed of the
fastest ISP connection. The other WAN interfaces remain comatose
because there's no way to bond the single destination IP to two
different download streams and routes. You can download something
else using the 2nd WAN interface, but you can't use it to increase the
speed of the first. Uploading has a similar limitation, where you
can't improve the speed to a single connection. Where such routers
work best is if there is a LAN full of users sharing multiple WAN
connections, not for a single user looking for "better throughput..."

I've used a few of these with moderate success:
http://www.edimax.com/en/produce_list.php?pl1_id=3&pl2_id=
(See load balancing and multi-homing routers near bottom of page).

Incidentally, multiple cient radios, run to a passive combiner in a
single omni antenna is a total loser. The FCC specifically proscribes
synchronizing wi-fi radios. Even if the isolation can be increased
sufficiently to prevent receiver overload, it's highly probable that a
receive packet will arrive exactly when some other client radio goes
into transmit. Some relief can be obtained by using different
non-overlapping channels (1, 6, 11), but only with expensive bandpass
cavity filters. The spread spectrum spreads quite nicely into the
spectrum of the adjacent radio.

Which raises the question, if someone uses your access point without
permission are you within your rights to do whatever you please with the

Is a unsecured wifi AP more like putting some benches on the sidewalk in
front of your house or a house with an unlocked front door?

This would a good example where the "law" isn't settled.

Unlike the door example, where there is millenia of houses and doorways
to establish a fairly common understanding of boundaries and permissions
required (and even then, it varies among places, right?)

To a first order, if you own one endpoint of the link (i.e the AP), then
you get to look at what its carrying. Unless you're a "common carrier"
or "utility" sort of organization.

And how far does YOUR liability extend, if, say, that miscreant out
front is using your AP to organize a terrorist plot? ISPs have a "safe
harbor": if they don't look at the content, they're not responsible.

Or, does having that open AP give you plausible deniability, and the
SODDI (Some other dude did it) defense... Hey man, it wasn't me
downloading copyrighted music to that IP, it must have been some other
dude with a laptop in a car out front. Bummer that I don't have any
traffic logs.

As far as the FCC is concerned, I suspect that the usual "third party
reception" rules would apply. If the communication is transmitted
over the airwaves but is not intended for you, you're permitted to
intercept the communication but *not* to make gainful personal use of
what you overhear.

There was one company which tried to prosecute some local "wardrivers"
who had publicized the fact that the company was running an open
wireless network. The FCC not only refused to pursue their complaint
(pointing out that the company had created the problem and failed to
mitigate it by turning on WEP), but cited the company for running an
illegal Part 15 network (they were using external high-power
amplifiers on their APs).

I'm reasonably sure that any criminal actions you implement with the
use of such data (e.g. making any unauthorized access to a protected
computer system, etc.) would *NOT* seen as legitimate by The Powers
That Be, even if you gained knowledge of that data by scarfing it off
of your own access point during an unauthorized use thereof.

As I understand it, there isn't any standard interpretation (even in
under U.S. laws) as to what rights-of-usage apply to an open access
point, in the absence of a statement by the AP's owner as to what the
rules are. The FCC doesn't appear to consider this aspect of the
wireless problem to be part of their jurisdiction.

I believe that in some areas, using such an AP without having received
some explicit form of permission is considered to be a tort (a civil
wrong) and the owner could file suit against you. Using the AP to
break into a computer network (e.g. accessing files, etc.) could
easily qualify as a prosecutable "computer crime".

I've read that some municipalities have passed a rule which says that
the act of setting up an insecure access point, and broadcasting
beacons "to the wind", counts as something akin to an open
invitation... enough so that the use of the AP without explicit
permission isn't considered a crime, or (I think) even a tort. This
might especially be true in the case of those APs/routers which come
with a WEP password pre-installed (the 2Wire models are one example)
and in which the owner must explicitly disable the security feature if
s/he decides that this is appropriate.

Nope. Two wrongs don't make a right. You'll also find that "an eye
for an eye" and retailiation are not actionable in the USA legal
system. Simply having your rights violated, does not magically make
it open season on the perpetrator. The courts are expected to deal
out the necessary justice, not you. For example, catching a burglar
in the act does not give you the right to pound him into the ground.
You can and probably will be charged with battery for doing that.

This has come in handy a couple of time now in just the last few

Funny story... I work as a contractor and was in an office in Louisiana
that supposedly had an internal wi-fi setup. Signal sure did seem weak
for an internal connection. All the guys there said they didn't know
what happened to it. "It used to work good".

Mr. Boss, the guy who installed it originally, was in town and said
"hey, whats wrong with the wifi?". Turns out the little wireless router
had fallen behind some other gear and become unplugged. All during this
time the office traffic had been going thru the network of a nearby
residence.

There are outfits that make Omni Antennas for the 2.4 Ghz Band, that
have Down-tilt designed into them. This helps deal with the flattening
of the Vertical Polarization for local connections. I have one located
on a 60ft Tower that has multiple AP's at various Azimuths, with ranges
out to 2 miles. Works well for a Central Distribution.

Agreed, for an AP, if 360 coverage is needed, an omni with downtilt
is an appropriate option.

Not for clients.

Alligator effect. Wide mouth receiving everything.

"Alligator effect" normally refers to higher transmit power (not higher
antenna gain) -- big mouth, small ears.

If you don't need to
pickup everything then why bother? It just makes it harder for your WiFi
router to cut through all the noise of distant stations it doesn't
communicate with. ...

It actually usually makes sense, since higher gain means narrower
receive pattern, which better rejects off-axis interference.
Interference in exactly the same path is possible but unlikely.
