Help with probing for access points programatically
 

I have a program that I wrote that can print out all the local access points that can be found to a file. I basically took iwlist and copied and paste what I needed.

The problem is that when I run the program, I usually only get one access point. The only way I can get more than one is to go to the wifi button on top of the N810, click it and select Change Connection..., and cancel without making a choice. This will result in my program printing out several access points instead of one. Is there a way I can programmatically get the N810 to reset the way it's collecting APs?

Thank you in advance and let me know if you need me to clarify.

Not sure how to tell you to do what you want, but would love a copy of the program you wrote... :)

You removed too much from the iwlist program. There is a section of code which initiates a scan on the device a bit before the result return, otherwise you just see the current result which is the associated AP.

I did something similar (iwlist light with hardcodes for n8x0) and it worked.

As I recall, if you use "iwlist wlan0 scan" as user, you see just your current AP, but if run as root, you see all of them. I wrote the following a couple of weeks back:

#!/usr/bin/perl
$id = shift ;
while (1) {
open (IN,'iwlist wlan0 scan 2>/dev/null|') or die ;
while (<IN>) {
# chomp;
unless (/SSI/) { next; }
if ($id) { unless (/$id/i) { next ; }}
s/^[\s]*//;
print $_;
while (<IN>) {
unless (/Qual/) { next; }
s/^[\s]*//;
print $_;
last;
}
}
}

There's also aircrack-ng available
