    Wireless connections are gone

    I've been using Ubuntu 22.04.1LTS 64bit on an early 2010s MacBook Air for a year and a half now. Yesterday, after a routine restart, I noticed that the device:
    1. Didn't connect to a wifi network
    2. Did not display the wifi icon/setting shortcut in the toolbar
    3. Does not display connection options other than VPN under the network tab in settings

    I attempted to remedy this by doing what other posts had suggested. I searched for network manager via terminal and was met with a "does not exsist" error. I then searched for the WPA and Network Services unit files and found that they were both enabled. Finally, I searched for my network card, a Broadcom BCM43224. It's there and I think functioning, but it keeps giving me a "network UNCLAIMED" message when I run "sudo lshw -C network." Finally, I attempted to uninstall and re-install the drivers for the card, this did not seem to do anything.

    **additional note: this device does not have an ethernet port and I do not have an ethernet adapter for the Light Peak port

    How about:
    Code:
    sudo dpkg -s bcmwl-kernel-source | grep Status
    lspci -nnk | grep 0280 -A3
