Thanks Kismet and BackTrack 4 and good old Acer Aspire One can also go fix an open Wi-Fi network related. I especially like the development towards Freifunk , even if German legislation such great initiatives to restrict unnecessarily strong. But as an open wireless network is everywhere but a good thing. But what happens when you make the antenna range is not quite sufficient?
I fared similarly. Although I'd network and e-mails handed it also perfect, but the thing was a catch: It seems the router radioed too weak. The built-in AA1 Atheros card did well and sent the package with amazing speed, but the radio signal from the other side was so weak that the packets slow the Netbook eintrudelten (if any).
why I came up with the idea of tinkering with my own wireless radio antenna. Even before I had read something here and there, but really I have explained to me is not finished. But now I wish I sometimes wonder whether I can do it;)
The problem is that of course I also need a chipset for the antenna. Most simply take their Wi-Fi USB sticks, and then solder to the antenna. But I have no such key, and why? The Atheros card in AA1 provide excellent services. And this I will certainly not turn rumfrickeln: p A new purchase is out of the question, where is there because of the fun?
Well, I did so just grabbed an old router. A Targa WR 500 VoIP. If you look closely, It is a real "scrap box" (compared to Fritz Box: p) and identical with the speed W500V the T-Com. They grabbed the position probed and cut the thing into its component parts. As you can see in the picture below, it is very easily possible to replace the antenna of the device.
with the normal firmware but then you get no further. Therefore, the modified fast easy BitSwitcher firmware onto the device (does not hurt yes, anyway, anywhere * inside * Linux g). This firmware is really awesome and gets the last out of the old box. It is possible the wireless hardware in the client mode enable and to a wireless network to join (otherwise, the device provides a separate access point). Just what I need.
Now it is easy to route packets from the wireless network to the LAN network. Even a bridged mode is available. So I just use the router via LAN as my wireless receiver.
Well, what's missing now is the antenna. With the built-in antenna, it is now, too, but the use to me even yet. I also need a field test, of course, a field in an open area. Should not be so hard to find, but one with a 240V connection already;). But if need be just to keep the converter to the cigarette lighter her:)
Continue So the construction of the antenna. The internet address of really interesting points. I think I will opt for a bi-quad antenna.
