I bought the Lenovo ThinkPad E580 without operating system and I am trying to install Ubuntu 16.04. Everything is working so far, except the WIFI is not. The strange thing is, that the internet is working when I plug in a LAN cable.

I think a wireless driver must be missing, but I can't figure out, which one I have to install. At the website of Lenovo it says that the Laptop should have the wireless adapter "Intel Dual Band Wireless 3165 AC". But I cant find that one.

$ lspci -nnk | grep -i net -A2

  • I believe this is your device: Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device b822 Please run: lspci -nnk | grep Realtek Is the pci.id 10ec:b822? If so, except for the ndiswrapper part, your answer is this: https://askubuntu.com/questions/1004014/asus-rog-strix-z370-egaming-wireless-card-not-working – chili555 Feb 15 '18 at 20:37
