Introduction to Netstumbler Tool




The tip wifi this time dedicated tool or software freeware Netstumbler that was very popular in the activist's circle wireless, Tool this went in the Windows environment, with tool this we could detect the network signal wifi that still is active, by knowing active signals at this time, we could monitor the interference size in our environment was, Netstumbler this also could comprehend the signal wifi that further from that could be caught by software monitoring the gift device wifi standard.

Generally this tool was utilised for the need hacking, the testing of the configuration of the network, survey the interference size, found the place that was quiet from the network wifi, and positioned the accuracy of the antenna direction (pointing).
Unfortunately netstumbler this could disalah used by the person to find the network wifi that was susceptible security him, then he could use few efforts to break into him, so could internetan free here.

Because of that utilised the step security that was maximal in access point you, when your point access security WEP and WPA him was active, Then Netstumbler will show the picture of the padlock in the signal wifi that WEP or WPA him was active, so don't attempt to underestimate the case.

By that of Netstumbler could do monitoring channel-channel that was utilised, the strength of the signal wifi, put forward SSID that was detected.


Netstumbler also could accompamied by GPS equipment, alhasil we could map the network wifi that was to one place, this is usually carried out while going, also reported MAC Address point access plus the frequency of his operation, recorded the level noise, as well as his comparison with the level of the strength of the signal.

So the tip wifi this time gave the suggestion to you to men-disable broadcast SSID you so that the network wifi you were hidden, could not be detected again by Netstumbler or tool other that was similar (nevertheless had several tool that could monitor SSID that already tar-hidden/was hidden), tool made by Marius Milner this could didownload free in www.netstumbler.com.

The tip of Wifi Outdoor Pre the Installation



Served by us Tip Wifi outdoor that was effective so that the blank that was connected could be established by the connection well, there were 3 factors that influenced the success of the connection:
1. Good access point
2. Quality Antenna
3. The interference/noise/the minimal obstacle

Before you carried out the installation wifi, ascertained you did survey before, in part that must be observed:
1. The blank clearance that wanted to be connected, to be precise how many Kilometre (the distance of air), increasingly far the distance then output power from point access must be increasingly big, likewise antennae must improve gain him (thought dB him).

2. Confirmed around the point that wanted to be connected had or not the obstacle, the example of the building, the tower, the tree etc.. If having the obstacle, observed how many metre his height. This to determine how many heights from tower that would we will get up eventually, because between the two points or more, don't have the obstacle, in principle the two antennae must see each other, if having the obstacle, clear could not be established by the connection

3. Observed between the point that wanted to be connected had the wave interference wifi that was other or not, if having you must record channel as much as you please that were used and that was not yet used, this to determine channel that will be used by you eventually, you could use software scanning netstumbler under Windows or Wifi Radar and Airsnort that under Linux, also you could observe the strength signal from networks wifi available, this was useful to ascertain the capacity from antennae and point access that will be needed eventually, increasingly solid the interference, increasingly high also gain from antenna and access point that must be used.
