Yeah yeah, I know that title sounds like a bad TV commercial, haha… so I came across this neat little thing this morning, and while it’s not the same as spending a ton of money on a real expensive router, it’s still kinda neat that it works - and to tell the truth, it works better than any of the cheap to mid-range “range extending” omnidirectional antennas I’ve seen… so that’s saying something.  Basically half a coke can is close enough to a parabolic shape that if the router antenna is placed in the focal point of the half of the can, it does the trick and boosts the signal a tiny bit.  Not much, mind you, but it took a router from a -40 to -38db range to -36 to -34db range - which is better than the range extender antenna did.
