This is how I get my internet in Japan. To get the ethernet cable up and over the balcony, I was up at 7am one morning, in my pajamas, trying to lasso the thing over the railing while some Japanese schoolchildren watched as it invariably came back down and hit me on the head several times before it successfully lodged itself between the rails. Win.
I ‘ve asked around, and this strange method is apparently the same in all six houses like mine that house the exchange students. I don’t know why no one has gotten a cheap wireless router. I’m sure it’d only cost the equivalent of $40 or so. I’m going to investigate later.
