Using NetStumbler

That's normal. The general principle remains that the smaller the number, the weaker the signal and vice versa.

Hihi!

Sry all!

Now I have an query about that. how does inSSIDer find networks?

What inSSIDer is doing is decoding all of the wireless packets that your NIC card receives from other access points broadcasting, even if they are not for your system.

If you have to play around more with the packets that are going in and out of your system i suggest that you take a look at www.wireshark.org or www.ethereal.com .

With those programs u can look inside of each packet that enters your nic card, or leaves, and look inside of the frame's of the packet for items such as destination IP, host IP, protocol being used, etc.... they are powerful tools.

thank you so much

The negative numbers are the signal strength expressed as a dB ratio relative to a reference level. So a negative number is merely telling you how many dBs less than the reference level the signal is. This kind of measurement is common when dealing with RF, but don't worry about it. Just remember that the bigger the negative number, the weaker the signal.
