content: Cantenna Repeater Router Alright, so I've been living without decent wifi for no short period of time... and there's a coffee shop less than a mile away from my house.  Does any one have any information on combining a router wifi-repeater and a Cantenna or a Yagi Cantenna in order to pick up a distant wifi signal, then repeat it locally so that it becomes useable for local devices? Looking for designs, the math/physics/engineering behind the designs so I can make sure I'm doing it right, etc. I know that 2.4GHz is the standard operating frequency for most wifi, but is there an easy way to find out what the exact operating frequency of a given wifi-router is? Is there any reason this wouldn't work? Has any one done/attempted this before? Edit: for any one else who has questions like this. https://www.youtube.com/watch?v=C7wm2j53B0k http://www.wikarekare.org/Antenna/WaveguideCan.html
