Just installed Ubuntu on new HP desktop "pavillion"all in one. Dual boot set up. I get the message no wifi adapter found when attempting to get online. What to do? Oh I do not know how to copy and paste my terminal info so it actually looks like it does on the terminal. (A little help with that would stop annoying people that are reading my questions.)

When I enter sudo lshw -C network I get:

So I followed the already answered question advice of making sure I had the correct kernel which is currently 4.15 and I have the most updated rtl8822befw.bin firmware installed and I still am getting the no wifi adapter prompt. I do not know all the commands that I could be using to get this solved. The adapter is found and operational in windows and the Ethernet cable allows me to get online for Ubuntu.

When I enter lspci -nnk | grep -A2 0280 I get:

02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b822]
    Subsystem: Hewlett-Packard Company Device [103c:831b]
    Kernel modules: r8822be

When I enter rfkill list I get:

0: hci0: Bluetooth  
    Soft blocked: no  
    Hard blocked: no  

Any other Ideas ?

  • I'm assuming the adapter is found under Windows? And, for the time being at least, you can access the internet from Ubuntu using an ethernet cable? – Seth Sep 2 '18 at 6:11

    Please add the output of lspci -nnk | grep -A2 0280 to your question to let us see what Wifi card it is. (If it's the Realtek RTL8821CE, as it is on other HP All In One's, then this is a possible dulpicate of askubuntu.com/questions/990378/…) – pHeLiOn Sep 2 '18 at 8:33

  • Hi Craig - I deleted some of my comments pointing to methods to download the driver for the rtl8822be - these are out of date as the driver is now in the Official Ubuntu Repositories. The driver should be there in 18.04 but something else is stopping it from working and letting you connect using your wifi card. – pHeLiOn Sep 5 '18 at 15:23
  • The output of rfkill list should suggest if something is being blocked by hardware or software. – pHeLiOn Sep 5 '18 at 15:32
