I tried some commands like iw list and iwconfig but couldn't see the supported wifi version (b/g/n/ac).

    The simplest way is to find out your card type and search online its capabilities. The command to find your hardware is lshw -c network. In my case, this gives:

     *-network
       description: Wireless interface
       product: QCA9565 / AR9565 Wireless Network Adapter
       vendor: Qualcomm Atheros

    Note, that in your case as shown in comments for your card it's just a lucky coincidence that the card product description shows product: BCM4352 802.11ac Wireless Network Adapter In my example description shows model only.
