Ubuntu – Ubuntu can’t detect wifi networks on macbookpro 13.3

14.04dual-bootmacbook prowireless

I'm new to Ubuntu and Linux in general and I'm not sure how to go about setting up my wifi. It doesn't detect any networks.

I'm using a late-2013 13.3" macbookpro with retina display, so it doesn't come with an ethernet port. I used this installation guide to dual boot Mac OSx and Ubuntu 14.04.

I have a second computer that runs windows 7 that I'm using to research this and I want to avoid purchasing an ethernet adapter if possible.

I also did not install/download any of the updates as a result.

Best Answer

Please run:

lspci -nn | grep 0280

The pipe symbol | is on the right side of my US keyboard on the same key with '\'. Is this your device? 

Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

If so, then bcmwl-kernel-source is correct for your device. If you still have the install DVD or USB, then you can find it and its prerequisite there. Navigate to pool > restricted > b > bcmwl and drag and drop the deb file to your desktop. Now navigate to pool > main > d > dkms and drag and drop dkms to your desktop. Now install both with:

cd ~/Desktop
sudo dpkg -i *.deb

Load the driver:

sudo modprobe wl

Your wireless should now be working.

If your device is not 14e4:43a0, tell us what it actually is and we'll proceed.
