Wifi Channel Scanner Plugin

[ektus]

Version 1.0.4 released.

Hi wood it be possible to get the results of the scan show up in a html5 table so they can be read by a screenreader?

This should be possible already. Well, not HTML5, but to get the information with a screen reader.

1) Install the gargoyle webshell plugin
2) enter the command

Code: Select all

iwinfo wlan0 scan

3) point the screen reader to the scrollable window below.

I don't have a screen reader, so don't know if this would work, but it should, as it's normal text in a browser window and formatted as follows:

Code: Select all

Cell 01 - Address: E8:37:7A:3A:11:30
          ESSID: "o2-WLAN37"
          Mode: Master  Channel: 13
          Signal: -78 dBm  Quality: 32/70
          Encryption: WPA2 PSK (CCMP)

Ektus.

Thanks for the info dude will have a try of that now. I need to save a txt file with all the commands I find because I cant remember them all.
This should help me out for now but if it's not to much work wood still be nice to have the plug-in work with a screen reader.

So how dus the dbm thing work for my ssid i get Signal: -69 dBm Quality: 41/70

So how dus the dbm thing work for my ssid i get Signal: -69 dBm Quality: 41/70

The lower the dbm value, the stronger the signal. For example:

Code: Select all

Cell 19 - Address: 78:8D:F7:F2:3D:5A
          ESSID: "Vodafone Hotspot"
          Mode: Master  Channel: 9
          Signal: -87 dBm  Quality: 23/70
          Encryption: none

That's the worst signal I have available in my neighbourhood. Barely visible, weak, low quality of 23 out of 70.

Yours is good, and the graphical plugin just displays those values bar-graph style, frequency in axis and signal strength in y-axis, with 100dbm at the bottom so the worst signal visilble is at least 10 units in height. The graphics will display some additional info, though. Depending on the mode of operation, the WiFi Signal does occupy not only the channel listed, but also the neighbouring channels above and below, in case of a 40MHz bandwith network on channel 1 it will use all channels from 1 through 6. The graphics therefore show not simple vertical lines, but wide mountains for each network across all used channels.

There's a much more verbose list available with the command

Code: Select all

iw wlan0 scan

This one includes an information block like

Code: Select all

	HT operation:
		 * primary channel: 13
		 * secondary channel offset: below
		 * STA channel width: any

So that network is active on channel 13 and uses a secondary channel below, the graphics shows a mountain from channel 7 up to channel 14.

Thanks! I'll add it in

[Lantis]

Doing some modifications after some testing with some pretty interesting NEW devices.
160MHz (including split 80+80MHz) support coming soon

[Lantis]

Along with the upcoming changes, there will also be a tabular way of viewing the data, which may be helpful to some users with screenreaders.

Code: Select all

SSID	Channel	Width	Mode	Security	Signal
BigPond	1		20MHz	b,g		N/A		-64.00

etc etc.
