Using the airport express to extend wifi connection
I'm a student at LSU. I am almost never home, but I can barely afford food much less wifi. I do most of my internet stuff at school, but I have like chemistry homework that I work on late at night. Last night I opened my mac and found that I can connect to a couple of my neighbor's wifi connections but I was wondering if there was a way to amplify their signal at my house with my airport express. I plugged it in and the light turned green for a moment but then stayed yellow. I opened airport utility and it didn't pick up my airport express. Is there a way to amplify their signal via airport express? If so, how?
