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
