How to Download Drivers for Broadcom BCM4360 Wireless Cards on Ubuntu 14.04

====================================================================================

If you're experiencing poor Wi-Fi performance after sleep/wake cycles with your HP Spectre x360's DW1830 card, it may be due to an outdated or incompatible driver rather than a hardware issue.

In this article, we'll guide you through downloading and installing the correct drivers for Broadcom BCM436-43xx wireless cards on Ubuntu 14.04, specifically focusing on the BCM4360 rev 3 model.

### Step 1: Identify Your Wireless Card

To proceed with installation, first ensure that your system is indeed equipped with a Broadcom BCM4360/43xx series card.

You can check this information using:

```bash

lspci -nn | grep wireless

```

This command will output something similar to `02:00.0 Network controller '0804': Broadcom Corporation BCM4352 802.11ac MAC+Bluetooth Controller (rev 01)` if your system is running on a compatible card.

### Step Additional Dependencies

Before proceeding with the installation, ensure that you have all required dependencies installed by running:

```bash

sudo apt-get update && sudo apt-get install --yes dkms libpam-ssd:i386 libc6-dev:i386 libc6-dbg: i386 build-essential net-tools git-core wireless-regdb firmware-b43 broadcom-wireless-drivers/brcm80211-firmware linux-modules-generic-lts-hwe36-s390

```

### Step 2: Download and Install Drivers

Now, let's move on to downloading the necessary drivers.

Navigate to 'Broadcom official site'(http://www.broadcom.com/support/ethernet-controllers/netxtreme-mx4-bcm57640) for Broadcom network cards. Select your operating system (Ubuntu Server 14.04 LTS in this case).

Scroll down until you find NetXtreme-M1 Gigabit Ethernet Driver & Network Drivers section and click on the corresponding download link.

### Step 3: Extract and Install drivers

Extract the downloaded tar.gz file to a convenient location, for example:

```bash

tar -xvf broadcom-netxtreme2-5.100.tar.gz -C /home/yourusername/Broadcom_Drivers/

```

Change into that directory using `cd` command.

Finally, run these commands one by one in terminal window with root privileges (sudo) to install drivers:

```bash

./configure --enable-dpms=y --with-kernel-include=/usr/src/kernel:/lib/modules/3.13.0-32-generic-pae/+/build/include/uapi -C /home/yourusername/Broadcom_Drivers/btcoexist \

&& make all \

&& sudo dkml install broadcom-wireless-driver/driver/*.ko

```

### Step 4: Reboot and Test

After successfully installing the drivers, you should now be able to connect to your wireless network without any issues.

To confirm this change has taken effect, simply reboot your system using `sudo shutdown -r now` command followed by a simple:

```bash

iwlist wlan0 | grep Mode

```

You should see output similar to: `Mode : managed`.

Congratulations! You have successfully installed the Broadcom BCM4360/43xx wireless LAN driver on Ubuntu 14.04.
