Is there an easy way to detect your Wi-Fi adapter's capabilities on Linux? I want to check if my wireless card supports IEEE 802.11ac.
iw list command (with the space in the middle) will show you the adapter capabilities.
This includes the modes the wifi card is capable of.
You will need to install the iw package to use that tool.
You can run
iwconfig to list all of your wifi cards/adapters, list their IEEE, frequency, connected ESSID etc. in a short and clean format. If you want more specific information feel free to use
iw list to see a lot more detailed information.
Some sample output (without being connected to router):
wlan0 IEEE 802.11abgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off lo no wireless extensions. eth0 no wireless extensions.
