I'm a newbie to linux. I'm trying to install AWUS036ACH to my Raspberry pi 4.14.34-v7+ i run these commands

$ sudo apt update $ sudo apt upgrade $ sudo apt --purge autoremove $ sudo reboot $ sudo apt install raspberrypi-kernel-headers $ sudo wget https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source -O /usr/bin/rpi-source && sudo chmod +x /usr/bin/rpi-source && /usr/bin/rpi-source -q --tag-update $ sudo apt-get install bc git -y $ git clone https://github.com/astsam/rtl8812au $ cd rtl8812au $ sed -i -e 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile $ sed -i -e 's/CONFIG_PLATFORM_ARM_RPI = n/CONFIG_PLATFORM_ARM_RPI = y/g' Makefile $ make $ sudo insmod 8812au.ko $ sudo cp 8812au.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless $ sudo depmod $ sudo reboot

when i run iwconfig

wlan0 unassociated Nickname:"WIFI@REALTEK" Mode:Auto Frequency=2.412 GHz Access Point: Not-Associated Sensitivity:0/0 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0

when i give commands

$ ip link set wlan0 down $ iwconfig wlan0 mode monitor //doesn't give me any errors $ ip link set wlan0 up

i checked if i could do packet injections with

$ aireplay-ng -9 wlan0 it isn't successful. Have you got any suggestions? Thanks

Try this:

$ sudo apt-get update $ sudo apt-get dist-upgrade $ sudo apt — purge autoremove $ sudo reboot $ sudo apt install raspberrypi-kernel-headers $ ls /lib/modules/$(uname -r) $ sudo apt-get install build-essential bc git dkms airmon-ng -y $ git clone https://github.com/aircrack-ng/rtl8812au/ — branch v5.1.5 $ cd rtl88* $ sed -i -e ‘s/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g’ Makefile $ sed -i -e ‘s/CONFIG_PLATFORM_ARM_RPI = n/CONFIG_PLATFORM_ARM_RPI = y/g’ Makefile $ sudo ./dkms-install.sh $ sudo reboot
