    Macbook 4,1 wifi trouble

    Hi Ubuntu community! It's my first time here, I'm new to Linux overall, and I could really use some help!

    I currently have Lubuntu on my 2008 macbook 4,1 however I'm having a real tough time getting the wifi to work. I know that my computer has a weird Broadcom Wifi driver after perusing the forums. I found this particular forum of someone having the same problem but the solution didn't work for me: https://ubuntuforums.org/showthread.php?t=2210202

    Currently I can see all the wifi networks, but none of them seem to connect. In the "Additional Drivers" tab, it won't let me select the broadcom device, and seems to always go back to "do not use this device."

    Here's some info that might help:

    tony@TonyHackbook:~$ rfkill list all

    Soft blocked: no
    Hard blocked: no
    1: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    2: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
    tony@TonyHackbook:~$ lsb_release -d
    Description: Ubuntu 18.04.3 LTS
    tony@TonyHackbook:~$ lspci -nn | grep 0280
    02:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4321 802.11a/b/g/n [14e4:4328] (rev 03)


    Thanks in advance!!

    Hello and welcome to the forum.

    Please click on the wireless script in my signature, follow the directions for running it and posting the results back here using the pastebin link created.

    Thread moved to Apple Hardware Users a more appropriate sub-forum.

    Please do:
    Code:
    sudo apt purge bcmwl-kernel-source
    sudo apt install firmware-b43-installer
    Make sure your wired connection is unplugged then reboot.
