I recently installed Ubuntu v18.4 on my relatively new HP Stream 14 using pendrive linux. I can access the internet using a usb to ethernet adapter, but can't seem to turn on my wireless card using a keyboard shortcut or terminal commands.

lsusb

I have attempted (as far as I know) to take all of the steps outlined in a closely-related thread to my problem: "[SOLVED] wifi not working ubuntu and ubuntu mate on hp stream 11," https://ubuntuforums.org/showthread.php?t=231915; and have also installed pastebinit as well as ndiswrapper. My laptop's output can be found at: http://paste.ubuntu.com/p/G68gTNnnMg/

I have also ran the following:

mike@Phantom-HP-Stream-Laptop-14-ax0XX:~$ lspci | grep Network 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device b822

Thank you again to anyone who took the time to go thru all of this. Your help is immensely appreciated.

UPDATE:

I found out from assistance that I received on Ubuntu Forums that Secure Boot was interfering with my on-board wireless card.

The command:

sudo modprobe r8822be

Gave an output of:

modprobe: ERROR: could not insert 'r8822be': Required key not available

I disabled secure boot using:

sudo mokutil --disable-validation

and after restarting the computer and inputing the requested key to disable Secure Boot at start up, my laptop began using it's built-in wireless card without issue.

For more info on how do disable secure boot, the article that helped me resolve my issue can be found at:

Why do I get "Required key not available" when install 3rd party kernel modules or after a kernel upgrade?

Happy Coding Everyone.
