Normally I would put an item like this in my "links" post, but I know so many people who have problems with their home wi-fi network that I thought it important enough for a solo post.  Here’s the deal: if you have a wire strainer you can use it to boost your wi-fi receiver’s power since it acts as a parabola that focuses the signal for your receiver.  Check out the post on Instructables for details on how they used a dumpling strainer to do the deed. They call it a "WokFi" which I like.

I’m willing to bet that any wire strainer will help, but since the dumpling strainer offers a wider surface than the average strainer it probably works better than a standard strainer.

Instructables also provides a DIY tip on how to extend the signal of your wireless router using tinfoil sails. Very cool.
