I installed Ubuntu on an HP WiFi-only PC. After Installation The OS does not find the WiFi device. This is my maiden voyage with Ubuntu. I suspect that I did something wrong.

  • Welcome to AskUbuntu! Is this a desktop computer, or a laptop? Either way, please give the make/model of the computer as well as the make/model of the wireless adapter/wireless card if known. Please [edit](https://askubuntu.com/posts/1176452/edit) your question with the output of `ip link show`, and `netstat -i` – David Sep 25 '19 at 00:35

    Welcome to Ask Ubuntu. You may not have done anything wrong, some brand devices are easy, many cheaper ones are not. Following the docs can be helpful, ie. https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide (if you get stuck, when you get to *device recognition and operation*, you'll gain details about your chipsets found in your device which are the key clues to fixing your issue, and us helping you). – guiverc Sep 25 '19 at 00:36

    Please open a terminal Ctrl+Alt+t and run: `lspci -nnk | grep 0280 -A3` Next, edit your question to show the result. Welcome to Ask Ubuntu. – chili555 Sep 25 '19 at 03:26

Disable Secure Boot in BIOS, connect to the Internet using your phone and run in a terminal

sudo apt update
sudo apt install bcmwl-kernel-source

That will install the driver.

  • You didn't connect to the Internet. The answer said to connect to the Internet using your phone. You just ran the command. If you don't have a phone, you can use an offline method form the duplicate link. – Pilot6 Sep 28 '19 at 07:47
  • i have a phone that was connected to the web. I used a usb cable to connect the phone to the laptop. – MFW Sep 28 '19 at 19:53
