Doing measures on a wireless network interface on Linux

dear Fellow Arduino-Experts

dear Arduino-friends: i am planning to do measures on a wireless network interface on Linux

we have various options to do some tests on that:

we have

a. GitHub - uoaerg/wavemon: wavemon is an ncurses-based monitoring application for wireless network devices on Linux. wavemon is an ncurses-based monitoring application for wireless network devices on Linux.

b. iwconfig command - which is pretty similar to ifconfig command; The iwconfig command
gives back the basic wireless parameters like the ssid, mode, channel, bit rates, and even the encryption key,
additional we have the power and much more.

Sample outputs:

wlan0     IEEE 802.11abgn  ESSID:"FritzBox"
          Mode:Managed  Frequency:5.18 GHz  Access Point: 74:54:54:64:37:FC
          Bit Rate=5 Mb/s   Tx-Power=23 dBm
          Retry  long limit:6   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=45/60  Signal level=-64 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:28   Missed beacon:0

the output we can see above in the iwconfig command we can see a bunch of information:

At first sight we can see the

MAC protocol - and the name that this protocoll has used
ESSID (Network Name)
The NWID
The frequency (or channel that is currently used)
The sensitivity of the WLAN
The mode of operation of the WLAN
Access Point address
The bit-rate
The RTS threshold of the system
The fragmentation threshold
The encryption key
The power management settings - very very interesting too

well we often use the iw command.

But what do we do if we want to see all connection the system (NetworkManager) has:

Ping every IP on your LAN and record the results.
