• modprobe rt2800usb #Load module in kernel
• modprobe -r rt2800usb #remove module from kernel
• or  [rmmod rt2800usb] #remove module from kernel
•  lsmod | grep rt2800 #check is load

Permanent load modules:

vim /etc/modules-load.d/rt2800usb.conf

• rt2800usb #add this line

Check if systemd service loaded the module:

• systemctl status systemd-modules-load.service
