Wifi adapter can only be set to auto mode

i use a kali machine of version 4.18.0-kali3-amd64.
the adapter i use is alfa awus 1900 with rtl8814au chipset.
i download and install the driver from https://github.com/zebulon2/rtl8814au
my problem is. i can only set my adapter to auto mode. Is it going to be a problem with wifi hacking?

Have you tried to change the mode to Monitor mode?

Step1: ipconfig and find your wifi adaptor [referred to as Interface], could be wlan0 or wlan1
Step 2: ipconfig [Interface] down
Step 3: iwconfig [interface] mode monitor
Step 4: ipconfig [Interface] up
Step 5: ipconfig or iwconfig (I tend to get confused)
and check if the mode is “Monitor”


i follow the step and the device only went to Mode: Auto
i can’t get it to monitor mode…

Can you paste the output? just so i can check it out
