Is there a tool like wifi analyzer for ubuntu?

Solution 1:

Network manager command line interface nmcli

nmcli d wifi

This is an output of command:

*  SSID           MODE   CHAN  RATE       SIGNAL  BARS  SECURITY

   Silviq         Infra  10    54 Mbit/s  4       ____  WPA2

But you can use:

nmcli -f "CHAN,BARS,SIGNAL,SSID" d wifi list ifname wlx10feed21ae1d  | sort -n

and output will be sorted by channel:

CHAN  BARS  SIGNAL  SSID          
1     ▂___  17      Nina          
2     ____  0       Yankovi

11    ▂___  10      Mihaylov

11    ____  4       Valia         
11    ▂___  7       epg72         
40    ▂▄▆_  60      mary5         
40    ▂▄▆_  67      151022

For continues scan you can combine with command "watch":

watch  "nmcli -f "CHAN,BARS,SIGNAL,SSID" d wifi list ifname wlx10feed21ae1d  | sort -n"

Solution 2:

You could use Wavemon. It's available in the Software Center, (or via apt, sudo apt-get install wavemon).

Once you have installed wavemon, open a terminal (CTRL+ALT+T) and type wavemon.

You could use linssid which offers a nice easy to use GUI for both the 2.4 GHz and 5 GHz channels. http://ubuntuhandbook.org/index.php/2013/08/linssid-wifi-scanner-for-ubuntu-linux-mint/

To install linssid in Ubuntu 16.04 and later type:

sudo apt install linssid

Solution 4:

There is one more tool In Ubuntu software Centre named as Kismet.

Kismet is a 802.11b wireless network sniffer. It is capable of sniffing using almost any supported wireless card using the Airo, HostAP, Wlan-NG, and Orinoco (with a kernel patch) drivers.

Can make use of sox and festival to play audio alarms for network events and speak out network summary on discovery. Optionally works with gpsd to map scanning.

you can install it from terminal( CTRL+ALT+T) also with
