I have one wireless interface that connected to an access point (AP), and I want to know which type of 802.11 protocol (e.g. 802.11n or 802.11b) is used to communicate with AP. I know there is a Linux command iw
can get some information of wireless interface, such as signal strength
. But I don't find how to get 802.11 protocol type by iw
.
The iwconfig <interface> command should also list the frequency of the link, and some google-fu should link that frequency to a given protocol as, I believe, each protocol (a, b, g, n, etc) use their own set of frequencies. – music2myear – 2016-11-18T23:32:47.123
@music2myear: Sorry, that's not correct. b, g, n for example all use the same frequencies. See here.
