How to determine which WiFi technology is currently used in connection?
Solution 1
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
Solution 2
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
Solution 3
Try and do this
lshw -C network
It should give you that information.

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 ?
EDIT
Alright, I have tried
sudo lshw -class network
and I got from that :*-network 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=192.168.1.108 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 ?
