I have install the Ubuntu18.04(LTS) to my PC, but the wireless hardware Intel Ac9560 is a disabled device on my pc, and I have already installed the drive from the intel site to my computer down at "/lib/firmware", after that I rebooted my PC , but it's also disabled, the internet by line is avaliable, but I usually use Wi-Fi at work or library, so how to solve my question? THX!!
