I have Ubuntu 18.04 Dual booting with Windows 10 on my HP-EliteBook-745-G2, and for some reason, I cannot seem to find WiFi networks through my WiFi adapter, but Ethernet works (however, Ethernet stops working properly if I shut my screen down, and go back into my laptop, forcing me to restart my laptop to use Ethernet).
What I have done that didn't work:
Uninstalled Kernels and reinstalled.
rtlwifi.newas a fix.
Tried connecting through a hidden network, with different networks in different places.
sudo service network-manager restart
So I thought I would create a new post to get a different perspective here.
Side note: WiFi works perfectly on the Windows side of things, these problems persist only on my Ubuntu boot.
The output of
lshw -C network gives:

Edit: Just for the people using edits to correct my grammar, 'I'd' is the same as 'I would'.
Another edit: Ran
rfkill list all and here's the results:
$ rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no 2: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: no
Then ran :
dmesg | grep wl to produce:
