How can I improve the Wi-Fi signal on my laptop?

Episode 1234 (27:28)

VJ from Tuscon, AZ
Dell XPS Laptop

VJ's Dell XPS laptop has a design flaw which prevents it from getting a good Wi-Fi signal in most areas. What is his best bet for improving his signal reception? Leo says that since the case of that XPS laptop is metal, it turns his own laptop into a mini Farraday cage. The easiest way to get around this would be to get a USB Wi-Fi dongle that plugs into the USB port. The advantage is that he will get far better signal reception than any internal antenna. And they're only about $20. Unfortunately, this is what happens when the price plummets on hardware to the point that innovation suffers.
