Scan Wifi using iwlist ?

brolly759

I am trying to use iwlist or any nodeJS way of scanning for WiFi networks and generating a JSON list. I am finding that iwlist is not working. "wifisetup" works fine but I every interface I try to use iwlist on says scanning is not supported.

Am I missing something?

Thanks

@brolly759 maybe wifiscanner through node
https://www.npmjs.com/package/wifiscanner

I tried that, using this JS Code:

const wifiscanner = require("wifiscanner");

//Returns appropriate instance of a wifi scanner
const scanner = wifiscanner();

scanner.scan((error, networks) => {
if(error) {
console.error(error);
} else {
console.dir(networks);
}
});

I get this:

root@Omega-1AF1:/node_modules# node test.js
{ [Error: Command failed: /bin/sh -c /sbin/iwlist scan
/bin/sh: /sbin/iwlist: not found
]
killed: false,
code: 127,
signal: null,
cmd: '/bin/sh -c /sbin/iwlist scan' }

@brolly759 seems you either do not have iwlist installed or an incorrect path. did you try custom arguments that give the path?

iwlist is installed. When I try running iwlist (interface) s , every network adapter says scanning is not supported.

@brolly759
Try to confirm the path to where iwlist is installed with which iwlist?
[edit]

root@Omega-FAF1:/# which iwlist
/usr/sbin/iwlist

But I think this is moot as it doesn't seem like iwlist functions correctly on O2's.
I've used aps to scan for AP's before if that helps:

# aps

WRTnode AP scaner.
Begin scaning APs, pls wait...
Finished.
APs available are...

iwlist is in /usr/sbin/iwlist

aps seems to work, though no nodeJS plugin for it. Maybe I can create an app that prints the
"aps" debug into JSON format.
