I posted this workaround in the other thread on this topic.
My solution was to construct a couple 9 dBi gain parabolic reflectors to slip over the dipoles on my Linksys router. The Blink is 70 feet from my wireless router and is behind four walls. With these parabolic reflectors, the signal strength at that location is presently 80%. It takes about 20 minutes to construct these parabolic reflectors. You just need some cardboard, aluminum foil, glue (spray glue is best), a printer to print the template and a pair of scissors. Here's a website with the template and directions
. The beauty of this solution is that I didn't need to purchase and configure a range extender, your WiFi signal is focused where you need it, it's passive so there's nothing to fail, and it's cheap.
