Q. I purchased a game console for the TV in my bedroom, but it turns out my Wi-Fi signal isn’t great there. What can I do to get a stronger signal?
A. Your Wi-Fi router antenna is likely omni-directional. Put the router as high as you can in the center of your house for the best coverage. If your router has to be near the edge of your home, a simple homemade directional antenna can send the signal where you need it.

Not only will it have a strong signal, it will be faster with newer gadgets. Need more? Here are other tricks that will boost a Wi-Fi signal for faster Internet and smoother videos.
