Trouble with ipconfig OpenWrt on Rp 4 b

Hello everyone,

I have problem with my openwrt I want to up wlan0 wifi card with installed drivers but when I typed: ifconfig wlan0 up , terminal stayed on this and don't changing for all times. I tried also ip link set wlan0 and I had the same issue. What's wrong??

Depends on the wifi card, doesn't it ?
Is it the built in wifi, or something else ?

it's usb wifi card awus036acm (mediatek chipset ) but I installed all needed drivers and here we go again the same issue like with awus036acs, when I typed ifconfig -a I seen my card on wlan0 but when I typed ifconfig I only seen wlan1 which is built in raspberry pi.
