Memory and storage are probably the two most commonly upgraded components on laptop computers. They're easy to upgrade and have an immediate impact on system performance. Wi-Fi cards are upgraded less frequently, but upgrading them can have a dramatic impact on performance as well, with greater range and faster throughput.

In this tutorial, we're going to upgrade the Intel Centrino Wireless-N 2230 inside a Toshiba U925t Ultrabook, with an Intel Centrino Advanced-N 6235. The Intel 2230 card is a good midrange card, but it lacks dual-band support, so we're going to replace it with the Intel 6235, … Read more
