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 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
