I recently installed Ubuntu 18.04.3 LTS on my Lenovo ThinkPad P1. It can now dual boot in Windows or Ubuntu. I have no idea how to get WiFi, it works fine with Windows.

In Software & Updates, it says under “Additional Drivers”: “No additional drivers available.”

Even when under “Ubuntu Software”, under “Installable from CD-ROM/DVD”, Cdrom with Ubuntu 18.04 ‘Bionic Beaver’ is ticked (usb with installation is plugged in)

I connected my phone to my laptop and got internet using tethering

As requested I got some more information:

  • Are you able to connect through ethernet, even for a short time. I mean, do you have access to the internet at all? – Jags Oct 07 '19 at 07:58
  • I have not tried ethernet yet, I can try it in 10 hours maybe – Maarten Meijer Oct 07 '19 at 08:00
  • Actually I don’t think I have the right cable, so a solution without ethernet connection would be better – Maarten Meijer Oct 07 '19 at 08:03
  • When you get internet access, you can run this Wireless Info Script: https://github.com/UbuntuForums/wireless-info as described in this AskUbuntu post: https://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos/425205#425205 It'll create wireless-info.txt file at the location it is run from; then edit your original post, and copy paste the output from that TXT file. Info about the script, as mentioned in the post, "we created at the Ubuntu Forums to collect all the most common information needed while masking all sensitive data." – Jags Oct 07 '19 at 08:03
  • Just read your 2nd comment. Since you mentioned WiFi works fine with Windows, if you feel comfortable, you could download the script in Windows, then reboot to Ubuntu, run the script, again switch the OSes, and update this post from Windows. Here's the download link from the same page: https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info Go through "Run from GUI" at the bottom of GitHub page. To make it "executable" using GUI, once in Ubuntu, right-click on the file, properties, click permissions tab, and select "Allow executing file as a program". – Jags Oct 07 '19 at 08:15
  • Another option would be, again if you feel comfortable, you can go to device manager in Windows, look for wireless adapter, and find make/model number of your WiFi card/adapter. Update your post with the info. That will help finding and installing correct drivers. – Jags Oct 07 '19 at 08:21

  • It seems that you redacted some information from lshw -C network. Please if you are pasting some outputs, paste it as it is produced. For your issue, see if chili555's answer helps. – Kulfy Oct 07 '19 at 08:31
  • @maarten-meijer it looks like wireless card in your laptop is: Intel Wireless-AX200. Please check the answer mentioned by"Kulfy". Also go through another answer by chili555. – Jags Oct 07 '19 at 08:43
  • All code in chili555's answer worked, except for the last instruction 'sudo modprobe iwlwifi'. It results: 'sudo modprobe iwlwifi' – Maarten Meijer Oct 07 '19 at 09:33
  • I reinstalled Ubuntu with proprietary software checked. I now have secure boot. I updated the information – Maarten Meijer Oct 07 '19 at 09:37

Apparently Secure Boot was enabled, which is also why chili555's answer did not work. I entered the bios and manually turned Secure Boot off. After this everything was fixed!
