I would like to check which 'technology' (a/b/g/n) is currently used by my WiFi card for the connection and to check which standards it can use.

How can I check that ?


Alright, I have tried sudo lshw -class network and I got from that :

       description: Wireless interface
       product: AR9287 Wireless Network Adapter (PCI-Express)
       vendor: Atheros Communications Inc.
       physical id: 0
       bus info: pci@0000:03:00.0
       logical name: wlan0
       version: 01
       serial: XX:XX:XX:XX:XX:XX
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
       configuration: broadcast=yes driver=ath9k driverversion=3.2.0-27-generic firmware=N/A ip= latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn
       resources: irq:17 memory:b5100000-b510ffff

So I can get form that my card's 'possibilities' wireless=IEEE 802.11bgn

but how can I get information about current connection ?


Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below:

sudo lshw -class network

If you get no response, you may need to install lshw on your system. You can install it by typing:

sudo apt-get install lshw 

I donot know if this is what you are looking for but you can get further information regarding wireless connection from iwconfig. Just do iwconfig WIRELESS_INTERFACE e.g iwconfig wlan0. You can also run iwlist WIRELESS_INTERFACE OPTIONS, see man page of iwlist for available options. According to man page they both retrieve information from /proc/net/wireless


Try and do this

lshw -C network

It should give you that information.



Another option is to use iwconfig

Can be used without sudo

$ iwconfig
lo        no wireless extensions.

enp2s0    no wireless extensions.

wlp3s0    IEEE 802.11  ESSID:"NETWORK"  
          Mode:Managed  Frequency:5.18 GHz  Access Point: XX:XX:XX:XX:XX:XX   
          Bit Rate=6 Mb/s   Tx-Power=30 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
          Link Quality=54/70  Signal level=-56 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:19   Missed beacon:0
  • This will not give me the actual standard used: 802.11a/b/g/n/ac – Patryk Oct 31 '18 at 9:48
