Hi please check dmesg output, you may have to disable Secure Boot.

Hi, you was right, I had secure boot enable, but after disabling the command sudo modprobe 88x2bu get this error in dmesg: [ 301.217512] 88x2bu: disagrees about version of symbol module_layout [ 311.211132] 88x2bu: disagrees about version of symbol module_layout

Hi RinCat, the problem is solved. I install another time buildessential sudo apt-get install make gcc linux-headers-$(uname -r) build-essential and after recompiling driver modprobe load it Thanks
