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 :
*-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'
but how can I get information about current connection ?
