    Howdy folks, I just thought I'd throw this one out there since a lot of you could really use the "free" Internet connection and/or the multiple connections for use with CL and so on.

    What I did:

    Bought this stuff:
    1. 24 dBi http://cgi.ebay.com/Outdoor-WiFi-Antenna-2-4GHz-Parabolic-Grid-24dBi-802-11-/140432773519?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item20b272118f
    2. http://cgi.ebay.com/Asus-WL-520gC-/170521189687?cmd=ViewItem&pt=COMP_EN_Routers&hash=item27b3dadd37, for use as a client with DD-WRT (although you can use any DD-WRT compatible router)
    3. http://slickdeals.net/permadeal/34928, which is on sale for under $10 total, which includes shipping (great deal)
    4. An N-Male to RP-SMA male http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160450716464&ssPageName=STRK:MEWNX:IT or http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110541334321&ssPageName=STRK:MEWNX:IT
    5. http://www.newegg.com/Product/Product.aspx?Item=N82E16833166022&cm_re=rosewill_usb_wireless-_-33-166-022-_-Product compatible with an external antenna

    What I do with this stuff:
    • First, I installed DD-WRT on the first router I listed. DD-WRT is software that enables you to run the router in "client mode", which basically turns it into a wireless receiver.
    • Next, I hooked the grid parabolic antenna up to the router running DD-WRT with the cable I linked to above. I later switched to a connector because the signal quality is better.
    • With the router in client mode and the antenna hooked up, I scanned for and connected to signals around my house. This takes a lot of work, and I ended up using a USB network card (listed above) in order to scan in real-time and to get the directional beam adjusted properly. Once you get a good signal, you can set everything up and leave it there, and it stays connected. With this antenna, I can connect from what seems like a few miles (I'm not sure about the actual distance).
    • Now that the first router is receiving a signal from a distant AP, I connected the second router (the cheap Verizon one I listed above) via ethernet to the first one. The second router then broadcasts the signal throughout my house, much like a regular router would do if I had my own modem connected to it. The second router acts like a repeater.
    • Free WiFi for a very long time! :)

    I also use this http://www.newegg.com/Product/Product.aspx?Item=N82E16833166022&cm_re=rosewill_usb_wireless-_-33-166-022-_-Product in cojunction with BackTrack, software that enables me to break the encryption on connections around my home. The USB NIC also allows me to scan in real-time in order to find the best signal and positions for the antenna. (You also can't get keys for encrypted networks without it.)

    Hope this helps you guys, because it helped me a ton!

    Don't forget to use macchanger (I think it comes with Backtrack) to change the MAC address on your wifi interface. It's the only thing by which you can be identified... unless you connect to a honeypot or something. :p

    I love DD-WRT. its an awesome firmware.

    thats one thing I hate about my current Cicso/linksys E1000 router(they suck ass!). there is no Tomato or DD-WRT firmware for it. i've been wanting to use it to broadcast multiple SSID from my router but no good hacks. if you know of any please share.

    I've heard of some guys using 10-foot dishes and reaching up to 120 miles. Pretty cool!

    No, there's no realistic way anyone will detect it. If you start doing crazy stuff like attaching amplifiers or something like that, you might upset someone, but nothing bad will come of the things I mentioned in my post. :)

    so there is no difference if we use the PCI based NIC card or is there something special about the USB version?
    Great Share!

    The difference for me is that this USB card is more versatile. I can attach it to my netbook rather than trying to deal with my dinosaur of a full-sized PC. I've also heard better things about USB than I have about PCI, although PCI-e might be a good way to go, too.

    This card is compatible with the antenna and connector I listed, cheap in price, compatible with BackTrack, and comes from a reputable company.

    You don't actually need a NIC at all, unless you want to connect to encrypted networks. You need the NIC to grab the keys, since a router as a client acts more like a simple bridge than a NIC. All of the upper-layer information is processed and handled by the router before the software on your computer has a chance to interface with it (as far as I understand).

    Hope that helps!

    Who said you need to break encryption? I'm picking up over 20 unsecured connections in one direction alone (and the beam width is small, so there are potentially hundreds if I were to swivel it around).

    And I said nothing will realistically come of it. You know that joke about removing the label from your mattress? It's kinda like that.

    Ummm you said it, then you said that nothing bad could come of what you said. I'm simply pointing out that thats not at all true. Unfortunately, some gullable people here will take what people post as the gospel.

    Look, I'm sorry if you're not a native English speaker, but you're not properly understanding what I'm saying. The word "need" implies necessity; me stating that I do something does not imply necessity. I do what you quoted out of choice, and it's not necessary for the entire process to work. Anyone familiar with computers at all--which you should be, if you're here--should know that you can connect to unencrypted networks just the same.

    And by-the-way, even if you connect to an encrypted network, the likelihood of anything coming of it is nil. Not only have I never encountered someone who even became aware of me connecting to their network at all, I'd imagine the general response would be to change the key or to set up MAC filtering. It's not like the Johnsons are going to phone in an FBI information specialist team to hone in on the guy next door using their Internet service. Nobody cares that much on any front.

    Edit: me and the OP kissed and made up via pm.:hug:

    I was not attacking you, I was simply pointing out the fact that part of what YOU posted CAN get you into trouble.

    Thats all, nothing more!!!

    YOU are the one who said that YOU use backtrack to break encryption, then later posted that nothing that you said could get you into trouble. Once again, I was simply pointing out the fact that thats not true.

    Here are just a few examples of what CAN happen.

    •2007 - a man in Michigan was fined for using the Wi-Fi hotspot of a local cafe, from his car


    •2006 - Illinois man David Kauchak was fined for unauthorized use of a local agency's Wi-Fi access point


    •2005 - a Florida man faced felony charges for piggybacking onto a neighbor's Internet connection without their permission

    Actually, you went from point to point, first implying that you're likely to get into trouble with this, and secondly implying that I said that anyone needs to break into encrypted networks. I don't think either of those are true. If your whole point was that it's illegal to steal WiFi, then you aren't getting your point across very effectively. The person asking if anyone would get into trouble with this was asking within a practical context; it's obvious that it's not always legal. Piracy is illegal, but I don't exactly need to start ranting about it in a thread regarding how to acquire a specific piece of SEO software for free. Do you think that listing a bunch of piracy convictions in that kind of thread would be relevant?

    How big is all of this. Like, would it all fit in a normal sized laptop bag you think?

    No, definitely not. The routers together are about the size of a shoe box. The antenna is a little over 3 feet wide and 2 feet tall, and the cabling takes up a little bit of space, too. Plus, you'll need to have a tripod or something similar to position the thing. I plan to make one out of cheap PVC from the local hardware store.

    The antenna is designed to be stuck on a roof or something, but I have it positioned in a room in the house. The walls degrade the signal a little bit, but not enough to make it difficult to get a lot of signals.

    Hope that helps :)

    You don't need your own at all. The point of this is to detect someone else's wireless signal, and to then bounce that throughout your house (although it is considered theft in some cases, especially if the signal is encrypted). I often stick to wide-open signals, and have been using the local McDonald's for my connection lately. They don't seem to notice or care, and since the signal is meant to be used publicly by customers, I'm assuming they'll never really check into it.

    Edit: and if I did continue to use the same signal for a while, I'd probably do what voyevoda mentioned and alter my MAC address every so often.

    What's the advantage of multiple SSIDs?
