Hi and welcome to LQ,

Firstly, does your wifi adapter work? I mean, can you properly connect to a wifi network using the machine?

Please post the output of the following commands:

first of all check your card is supported for monitor mode or not.

root:~# lspci -v | grep -A 6 "Network"

lspci didnt show anything

what should i do to know my adaptor support in monitor mode or not?

Ok, we confirm it is wlan0, up and working.

To check the compatibility of your adaptor, you should check if it is supported by aircrack-ng (in which airodump is a part).

Please read this: https://www.aircrack-ng.org/doku.php...mpatible_cards

i cant open the page, but when i see https://www.quora.com/Does-TP-Link-W...-in-Kali-Linux, it said my adaptor not support for it
could you give me a suggestion what is the best one adaptor in my lenovo laptop for kali linux?

Networking is disabled by default in Kali so have you enabled wireless. The Kali documentation site below has answers to a number of questions on wireless problems so I would suggest you go over that first if you have not.
