We've shown you how to boost your Wi-Fi range, but if you have an old satellite dish lying around, you can do your Wi-Fi a favour by pointing the antenna at the dish for a nice range boost.
Reader hhbhagat1417 explains how he discovered thsi trick:
To get better router reach, you can point the antennae of a router to a detached satellite dish. Then just position the antennae in such a way the efficiently bounces the signal and increases the range. (I know this description may not be that specific, but I think you know what I'm talking about)
After I did this, I got much farther range. I can't measure at this moment how far it reached. The effectiveness depends on the size of the dish and the shape of the parabola.
I don't have any satellite dishes to try this out on (though you can bet I'll be scrounging one up the next time I'm at my parent's house), but a quick Google search reveals a lot of similar (but much more complicated) DIY hacks, so this might be a less-involved option. If you've got an old dish lying around, try it out and let us know how it works for you in the comments.
