How to check wifi networking standard of current connection
Solution 1:
On Windows (tested on Win7, should be compatible with Vista back to Windows XP):
C:\Users\kuba>netsh wlan show interfaces
There is 1 interface on the system:
Name : Wireless Network Connection 2
Description : DW1520 Wireless-N WLAN Half-Mini Card
State : connected
Network type : Infrastructure
Radio type : 802.11g <-- the currently negotiated value
Authentication : WPA-Personal
Cipher : CCMP
Connection mode : Auto Connect
Channel : 11
Receive rate (Mbps) : 54
Transmit rate (Mbps) : 54
Signal : 82%
Profile : xxxx
Hosted network status : Not started
On many Linux flavors (including Debian) use iwconfig
. Although it doesn't display a string such as "802.11n", it does display Bit Rate:54 Mb/s
among other settings.
