Network slow on ubuntu machine

I have lately changed my laptop from windows to Linux. Since then Internet connection from this laptop is extremely slow. It's taking forever to open web pages.

I am running on Ubuntu 14.04. How can I troubleshoot this network problem?

I tried this sudo tee /proc/sys/net/ipv6/conf/all/disable_ipv6 <<<"1"
as I found in a different post on this forum but it didn't work.

Edit:

The output of lspci -knn | grep Net -A2 :

08:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

    Subsystem: Hewlett-Packard Company Device [103c:2230]

    Kernel driver in use: wl

For Chip ID BCM 4311, 4312, 4313, 4321, 4322, 4331, 4352, 4360, 43142, 43224, 43225, 43227, 43228, and others as suggested by Broadcom.

The propietary Broadcom STA Wireless driver is maintained upstream by Broadcom. As this driver is closed source, fixes in the driver itself may only be provided by Broadcom. As a convenience, Ubuntu offers two versions of this driver:

The bcmwl-kernel-source package aims to offer a later version for a given release. Instructions for installation may be found later in this article.

The broadcom-sta package aims to offer an earlier version for a given release. For further installation instructions, please see here.
