Wireless Broadband - Hurray and WTF Question
« on: February 09, 2009, 05:55:13 PM »
So as some of you may recall, every time I have to go to take care of my rentals, I stay at my folks' farm, on the "in the boonies" side of town where there has been no broadband available other than $80/ mo satellite (not worth 4-5 days per month of use)  and I've been stuck at around 14.4k modem speeds.

I was configuring a Verizon broadband card for a work laptop this weekend, and for the heck of it, took it to the farm just to try out. Yippee!! They have EV-DO there now! So I'm getting myself a card and getting one of these slick Linksys broadband card routers for their house, which lets you plug the card into the router and share the connection via wireless or wired DHCP. I just found out about them when trying to come up with a workable networking solution for one of our research vessels at work -- these are WAY slick! No more cussing while surfing APS and waiting for some of your damn oversized embedded images taking two hours to load!  :laugh:

So the WTF question is when I had the laptop at the farm, the regular wireless card was picking up unsecured "free wireless" at their house (the kind you often see at airports that usually leads me to believe someone is hoping you'll logon so they can get into your computer). The laptop I was using was a travel laptop with no critical info on it, so for kicks I let it try and logon. It worked and I was getting working Internet. The signal was weak, but stable for the few minutes I remained connected.

The closest neighbors are 1/4 mile away and I know they don't have wireless. The next closest are about 1/2 mile away and it expands from there. So does anyone have an idea where this signal might be coming from? I can't believe it would be worth a crook's time to hang out in a sparsely populated area waiting for someone to try and logon to a free wireless service that they are transmitting.

Metal structures and the like can cause wi-fi to bounce around quite far. 

IE: Cantenna

ETA:  That's still quite a ways out there.

My guess is someone set themselves up a fairly powerful antenna to broadcast wireless for their neighbors who for some reason or another couldn't get it on their own (either couldn't afford it or was in a non-coverage area for standard access).  My dad was thinking about setting up something similar at the family farm when he finally retires and moves back there.

I could see someone wanting to be a pal and help their neighbors out, but the fact that the connection name showed up as 'free wireless" kind of made me suspicious. The closest commercial building (gas station, coffee shop, whatever) that would potentially have free wireless is about 5 miles away, and there's only a few of those. Lots more in the 10 mile plus range.

I have shared my cable connection wirelessly, in the past. 

Lets just say that, with a PhD electrical engineer on the other end who specialized in finding hardware for RF sensors, we had REALLY FREAKING GOOD signal between us, using directional antennas and, uh...other means of boosting the signal.

Huh, never thought of a crook using free wireless as a means of access. So if you're using a public access node (in a airport or coffee house or w/e) how do you know it's legit?

Maybe its the back side of the cern black hole.
I needed a mod to change my signature because the concept of "family friendly" eludes me.
Just noticed that a mod changed my signature. How long ago was that?

It is all the tin foil that you are wearing that helped increase the signal strength.
There are five things, above all else, that make life worth living: a good relationship with God, a good woman, good health, good friends, and a good cigar.

Only two defining forces have ever offered to die for you, Jesus Christ and the American Soldier.  One died for your soul, the other for your freedom.

When it comes to system intrusion, the more tinfoil the better. A lot of IT security experts refuse to use public wireless at all.

Balog -- here's a short article on the "free wireless" thing:
