I asked this question before and now the problem came back. Every once in a while, I have to disable and re-enable Wi-Fi in order to make the browser work again. When the problem occurs, the page loads for a long time and then comes with a server not found or server timeout error. The output of lspci -kknn | grep 0280 -A2 is:

$ lspci -kknn | grep 0280 -A2
02:00.0 Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)
Subsystem: Apple Inc. AirPort Extreme [106b:00f5]
Kernel driver in use: wl

Before the problem seemed to be installing the wrong driver. However, now I am using the wl kernel driver which is said to support my Broadcom Network Controller [14e4:4331]

I have Ubuntu 14.04 LTS (Trusty Tahr) as a partition on a MacBook Pro with Mavericks (10.9.5)

Please remove the incorrect driver:

sudo apt-get purge bcmwl-kernel-source

With a temporary working internet connection, install the required firmware:

sudo apt-get install firmware-b43-installer

Reboot.
