So I went to the Apple Store to try to extend my warranty on my Macbook, but, unfortunately, I thought I bought the Macbook a year ago today, but it turns out it was a couple of days before that, so there went that! So with the remaining money I was going to spend on Apple Care, I ended up buying an Airport Express. The reason is because I moved in to a new place in May and my previous internet provider, Verizon, can't give service where I'm at. Alas, the only signal I can get is from a free, public, wireless network that Airport picks up, but that signal goes dead on the other side of the house, where my iMac is. So I thought if I plugged in the Airport Express somewhere in the middle of the house, it'd extend the signal, but it's not. Is there something I'm missing or not doing right? Thanks!
