I recently purchased an HP Stream 11 (HP 11-y020wm) and installed Ubuntu on it, but I'm having trouble getting the wifi card to work. Here's the results of the wireless info script I found on the Ubuntu Forums and I did run the updates before trying it, as described in the post.

Oddly, when I got to wifi settings, it says that no wifi adapter is detected, but the bluetooth settings display normally when I thought they both used the same wireless networking card. It even allows me to pair devices, but after the initial pairing, it won't let me transfer files or connect headphones.
I'm currently using a Wifi dongle to access the internet, but would prefer to not have to use it since my device only has two USB ports.
EDIT: Result of sudo modprobe r8822be
is modprobe: ERROR: could not insert 'r8822be': Required key not available
sudo modprobe r8822be
