How to make my pci wifi card rtl8822 working on ubuntu
I installed Ubuntu 17.04 on my HP OMEN 15(2017) laptop and found wifi card not working. I followed some advice from My WiFi adapter is not working at all, how to troubleshoot? | Ask Ubuntu I identified the wifi card id is Realtek 10ec:b822.
I found some information on these websites:
the product info site: RTL8822BE | Realtek.com
driver for windows: Realtek RTL8822BE Wireless LAN Driver for Windows 10 (64-bit) | support.lenovo.com

Updated Answer for 18.04
The accepted solution here is out of date for Ubuntu 18.04 - the rtl8822be is supposed to work out of the box.
- During installation, Ubuntu should detect what Wifi Card you have and install the correct driver for it, but to search for any further available drivers on Ubuntu 18.04, go to the Software & Updates program and click the Additional Drivers tab.
('Software & Updates' can be found by clicking 'Activities' in the top left of your desktop. Typing 's' in the search box should be enough to show the available relevant programs)
- Another occasional 'quirk' that has occurred is for Secure Boot to have an issue with the signing of the driver and preventing it from being loaded.
You can make sure that Secure Boot is disabled by checking your machine's BIOS settings (usually accessed by pressing a specific key chosen by your manufacturer, such as f2 or esc when you switch your computer on, but the Grub Menu also lets you select 'System setup' to take a look at your options).
- In a few cases, a Software or Hardware block can be preventing the Wifi from connecting. You can check for this by typing
rfkill listinto the terminal.
If you are still experiencing issues, there is a good troubleshooting guide here: https://help.ubuntu.com/stable/ubuntu-help/net-wireless-troubleshooting.html.en
I just got this working, it is fairly easy all up (after googling etc.)
-
Install the latest 4.14 kernel with the driver code, (from the instructions here)
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-headers-4.14.0-041400_4.14.0-041400.201711122031_all.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-headers-4.14.0-041400-generic_4.14.0-041400.201711122031_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/linux-image-4.14.0-041400-generic_4.14.0-041400.201711122031_amd64.deb sudo dpkg -i linux*.deb Download the
rtl8822befw.binfirmware file from here.Save it in
/lib/firmware/rtlwifi. Please note newer distributions may have this file already in here.Reboot.
Enjoy
Please note that this driver is still in staging at the moment, so use at your own risk!
