    After a successful install on my 2008 Macbook and update installs the wifi just dropped off. Did some research and found that turning off wifi management might help. After turning off wifi management all of the icons at the top of the screen disapeared. I turned wifi management back on so I'm back to square one again. I decided to try something else. Used my cell as a wifi hotspot keeping it right next to the laptop. Success! Is the problem a driver issue that causes the hardware to detect the signal as weak and is there a workable solution? In the meantime I'll just use my access point to connect to the web.

    Hi Grady, I have the same problem with a fresh install on a Lenovo Thinkpad T460 - wifie gets constantly turned on ad off.

    Tried everything - from installing the proprietary broadcom driver to the BIOS settings - it simply keeps happening whereas my macbook and my cell have constant wifi. >Any help available?

    I installed Elementary OS on my Macbook and an older iMac that i have and both have the same problem. I decided to try and use my phone as a Wifi hotspot and keep it next to the Macbook when I use it. That works so I use the Macbook with my cell close by when I use it. I dedided to put the iMac right next to the router to see if that would solve that issue and it did. It has to be a driver issue. For the time being i'll leave things as they are and see if the Wifi issues are solved in the next verson of Elementary OS. Either way I have nothing to lose since my older Apple hardware is pretty much un-upgradeable from a software and worthless otherwise. I tried other linux distros (Manjaro, Linux Mint) but both didn't recognize or install drivers for the Wifi adapter. Try what I did and see if it works for you. Good luck!

    Hi, Grady. Let me share what I did when I had the same problem as you. There are mainly two issues concerning wifi connection. One is related to DNS server settings, and the other is concerned with linux headers. If you got the wifi signals on the upper right corner, you might need to specify your name server. It's simple. Go to the network setting and click on the IPv4 setting tab. Add a DNS server. (Type in 8.8.8.8, 8.8.4.4), which is the google DNS server. If you haven't got the wifi signal indicator lit up although you have already got the bcmwl-kernel-source installed, probably, you have the latter problem as adwilson99 just mentioned. I ran the following commands and got the wifi driver working on my macbook 2009. It might be worth trying.

    $ sudo apt-get update

    $ sudo apt-get install linux-headers-$(uname -r)

    $ reboot

    I hope it will help you solve the problem.
    Good luck!
