In this instructable I make a common WiFi Thumbdrive into a beefy wifi extender!'

The parabolic Asian cooking(dumpling) strainer is the perfect candidate for this project.

I was able to pick up 20 more access points in the city and connect to a network a few blocks away!

This is BY-FAR the most simple of all Wifi extensions!

Image 2:
_best paint'job EVER!_ - This is the general Idea behind the parabolic dish.
- it should bounce all waves from the dish into the focalpoint (wifi thumbstick).

Step 1: GO GET STUFF!!!

OK, you have to get :

a) Cooking strainer from Asian food market.
- Needs to be PARABOLIC
-The wooden handle on mine made it easy to work with.
-Cost $7.00
-Mesh should be similar "tightness" as pictured. (Don't get the loose mesh)

b) USB Wireless Thumb Drive (g or b/g)

c) USB extension. -- The longer the better.(but get as much as you need.)

Step 2: Prep and Build the Signal Strainer!

Image 1:
-Using the snips and cup out a hole JUST big enough for the USB extension cord.

Image 2:
Squeeze the tip of the USB cord through hole.

Image 3:
-Adjust everything so the thumbdrive is at the FOCAL POINT of the parabola (I just eyeballed it).
-Fasten the USB cord in to place.

Step 3: Testing the Signal Strainer

Testing the Signal Strainer:

1) Find your favorite access point!
2) get as far away as possible! (While keeping line-of-sight)
3) Use software like NetStumbler to see the signal strength.
4) Adjust your Signal Strainer where necessary.

OK, enough of these legal/illegal stuff, this is not a court, I don't like lawyers (same as senator & congressmen) so please post some results instead, ok? cheers, and cool guys...

Haha, yes. Very illegal. But fun!
it isn't illegal if you don't get caught
And it isn't illegal in the first place too!
no : )
Show me the law that states that connecting to unsecured networks are illegal...
it is a felony in michigan
Im in texas,

Derp
in Texas, the statute is Penal Code section 33.02, Breach of Computer Security. It says, “A person commits an offense if the person knowingly accesses a computer, computer network or computer system without the effective consent of the owner
yes...CONSENT of the owner...that means if you were hacking into the network, your not getting consent, but if its an unprotected network its not illegal. PLUS if your network is unsecured you have no right to complain if someone got your internet. that code has to do with breaching network security. ie, hacking your school system's network to change your grades.
I made an account just to reply to this.

@ sokamiwohali

What you say IS true. At first glance, one might think "consent of the owner" would mean that one would have to receive explicit permission from the owner in order to use his or her wi-fi network.

The fact that the network was unsecured, however, changes the game a little. Although it is illegal to break into, say, an "unsecured" (unlocked) car or house, the physical realm is much different than the digital realm. I have never received explicit permission to access this website, or google, or any other website for that matter. An unsecured wi-fi network is conceptually no different than an unsecured website. The protocols and hardware used are very similar as well.

TL;DR: In the real world, the power is held within the hands of the owner(s). On the internet, if it isn't secured, than by default it is public.
A WiFi is open if it SAYS it is open or free. Otherwise you are stealing bandwith and can be charged.
WELL...let me first start off by welcoming you to the Instructables community. i hope your time here with us is ABSOLUTELY GRAND, and i cant wait to see what kind of ideas you have that you will post in the future. Im Subbing to you.

Now for the reply...lol

you confirmed that my comment is correct in the information i gave good sir. If a network is unsecured, the owner of the network is giving non-verbal consent to ANYONE who wants to use it...think about Starbucks or Mickey-D's...*MINUS THE TERMS OF USE PAGE* if you were to accesss their wifi, since it is unsecured, its free game.

As far as your accessing this, or any other website...your true to a point...you can access this website [or the others], BUT if you want to enjoy the fruits of your and everyone elses labor (ie: your having to join to even comment on this post (not trying to be a butthead btw. plz dont take it that way), e-books, etc.) you need to be a member (and throw in the pro membership as well for the downloads). HOWEVER do not let the statement i just said lead one astray...NOT EVERY website requires one to have a membership to enjoy the site fully.

Very true on your last statement tho...thats why i secure my WIFI. i know how it is with accessing unsecured WIFI...when i was in college i didnt pay one red cent for the internet i used...and i accessed from my room...haha...good ol days!!
heh heh... penal

illegal to crack protected wireless networks ;)
all the tools required to do it are on the internet

btw, i deleted that last comment for a reason, you should do the same
And do you know how to use these "tools" :D
sure do there's a tutorial
 Lol, it isn't illegal if they don't know it was you.

I went into my neighbors unprotected wifi and logged into config, which they hadn't set new credentials for and i changed their network name to HACKED just for fun :P
That's not nice at all....
could be. if he wanted to make them aware that their network is insecure.
Strangely there is legal precedent in the united states of America that "the airwaves are free" and if someone broadcasts signals onto your property, such as satellite signals, you are free to fiddle with decoding the signals as you wish. However the satellite companies have been getting around that for a long time by using copyright and other methods to say that if you use their secret pattern to decode the signals then you are violating their rights. But even in copyright and patent law there's nothing against doing "it" for yourself as long as you are not giving "it" away or sharing "it" or profiting from it.

(Now I expect to see a storm of responses and counter-responses to this, but that's what comments are all about, right?)

In Lebanon Nothing Illegal!! :P
Illegal --> illegal (the "i" was written in caps)
Is it in Lebanon that they cut off your hands for stealing? Or am I thinking of some other place nearby?
haha :O
man.. it seems u know nothing about lebanon!
these countries u're talking about are like "saudi arabia, and "morocco" and these so arab islamic countries.. (anyway i dont think they still do that)
lebanon is located in the Middle East.. near cyprus, and limited by syria from the east and israel from the south..
actually i dnt like to say that lebanon is an arabic country..
we do speak arabic.. but education systems are english and french thought.. (schools teach in english and french, in majority, all scientific subjects and literature .. and some of them teach it in arabic..)
and btw.. the Lebanese Republic's President is always Christian!..
u better do a research about lebanon to know more..
and plus the internet is way over priced and wayyy to slow! its not even worth it!!
i'm pretty sure there are some things you will not get away with
yeah i know that for sure..
actually i was just kidding, but i don't think they'll get you if u hacked a wifi connection or a personal email address!
they may only get you if u did something really illegal like cyber-criming or anything like that..
That's what i thought, but then she told the cops... then it got awkward...
I always enjoy people's receptiveness in accepting unreasonable legalities surrounding WiFi usage. I don't hack WiFi. Depending on where you live, there may or may not be laws surrounding this issue. Using unsecured WiFi in my opinion is not illegal and never should have been labeled as such. I do it all the time, everywhere I travel. If they have unsecured fileshares, I may also take part in copying or deleting whatever I like as well. If your country labels you as breaking the law from using anything left lying around unsecured, you should lobby your government to change the laws. It is my right to use whatever is left behind. Almost like someone calling the cops after leaving their belongings at a swimming pool locker overnight unlocked and then finding out that it isn't there the next day. You can take it to a certain level when you really gotta re-evaluate your sense of reasonableness.
Cool... Now i Knew.. how to use my Kitchen stuff.. Thanks bro...This verry usefull

I have an imac with a built in airport. will this solution work with the imac? also does it mater what wireless usb thing i use?
For iMac users, you have to buy the "iWok strainer" from official Mac Store. It's exactly the same, but painted white with Mac logo, and it costs $300.
Or the Linux version, which you can download for free.
You free dumplings with it as well.
