Boost a Weak WiFi Signal
Although many campuses boast “wireless access everywhere,” sometimes that signal never will reach your end of the brick-walled dorm. Unless–of course–you concoct your own satellite dish.
I don’t have a need for a WiFi booster, but this it a great solution for any student frustrated with a lousy connection. The ingenious frugality of some people never ceases to amaze me. And this makes for a great Sunday project/scavenger hunt.
