Hy 🙂

I look for a command lines which allow me to know  
which protocol 80211 (b/n/ax …) supports my wifi interface.

Some people tell we can with iwconfig but i try i have it :

```auto
wlan0 IEEE 802.11 ESSID:off/any
          Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
          Retry short limit:7 RTS thr=2347 B Fragment thr:off
          Encryption key:off
          Power Management:on

wlp1s0 IEEE 802.11 ESSID:off/any
          Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
          Retry short limit:7 RTS thr:off Fragment thr:off
          Encryption key:off
          Power Management:off

wlP1p1s0 IEEE 802.11 ESSID:off/any
          Mode:Managed Access Point: Not-Associated Tx-Power=-2147483648 dBm
          Retry short limit:7 RTS thr:off Fragment thr:off
          Encryption key:off
          Power Management:on

```

Ieee line doesn"t return the protocol ☹

with lsusb or lspci, some driver give the protcole but not all ☹

You can list your hardware’s capabilities with `iw phy`. Things to look for are `HT`, `VHT`, `HE` and `EHT` for b/n, ac, ax and be.  
Additionally you can see the supported MCS indices.

yeah iwconfig and ifconfig are basically older deprecated utilities. I generally recommend people learn ip and iw as that is where all the new technology is better supported.
