Not wishing to pay $50 to $100 for some gadget in the store. I found a pattern for a Parabolic Reflector that I stuck to the antenna on the desktop. Not only did I find it boosted my WIFI signal reception, I came to find 10 more WIFI connections in the neighborhood that I previously did not know existed.
In order to create the WIFI booster you will need tinfoil, stiff stock paper for your printer, a scissors, pattern and some paste. it takes about 10 minutes to make the WIFI booster.
The WIFI booster pattern is right below. Once you have printed the pattern cut out all the parts. Take the parts put ample paste on them and then cover with tinfoil shiny side facing out. Put it all together slip the center part over your antenna and your off to better WIFI reception.
Enjoy let me know how it works out for you
