    No Wireless Interface

    I have an up-to-date Kali Linux 64-bit installation. My Network Controller is Broadcom's BCM43142. Currently the issue is I'm unable to use wireless, I had no issue using it by default with Ubuntu Gnome, but switching to Kali, for some reason it didn't like that. Currently tethering my phone to my laptop, which is why usb0 is there.

    Installing compat-wireless allowed me to enable wlan0 (and apparently wlan1 at the same time). However, my situation isn't any better. It doesn't see any of the networks (even though I'm right next to the router) and it doesn't allow me to manually connect via SSID.

    Headers & Driver Up-to-date as well.
    Code:
    linux-headers-amd64 is already the newest version (4.12+84+kali1).
    linux-image-amd64 is already the newest version (4.12+84+kali1).
    broadcom-sta-dkms is already the newest version (6.30.223.271-7).
    rfkill list (ignore the soft blocks, I have them on so as to not potentially interfere with usb tethering)

    Installing compat wireless was unnecessary. They are obsolete packages of backports and backports are used for old kernel versions which doesn't support newer hardware. Why are you following old internet guides?

    gedit /etc/modprobe.d/blacklist.conf

    Type:
    blacklist ideapad_laptop


    Save the file & Reboot.

    There was no blacklist.conf file. However there were a couple files containing 'blacklist' in the file name. I tried adding what you suggested to each of them one at a time, and finally tried creating the blacklist.conf file. None of those worked. If compat-wireless was a waste of time, then I'm simply back at the issue of having no wlan0.

    That's not possible. Show the output of ls /etc/modprobe.d Also the show the output of lsmod..

    In my directory there are only two with that name and one of them is blacklist.conf
