Wow, it's been a while!
Fortunately I didn't manage to beat my predecessor's record of 2 months waiting for internet, but I came pretty close! There were so many complications...what's the name on my phone line? Not mine, not my predecessor's, not Shizuoka Prefecture..it turned out to be my pre-predecessor, who very few Japanese teachers at my school remembered so we had to do some digging in files to find her surname.
Yahoo BB, my internet provider, is trey-ridiculous about the name on the phone line. They won't tell you if you call them so you have to guess and they say yes or no. You can ask for hints but it's at their discretion whether or not they give you them!
Firstly, I applied with the name of the Prefecture and heard nothing for about a month. After harrassing Yahoo BB they finally sent me a letter explaining that the name was wrong...yeah, worked that out thanks! So I applied again and the modem arrived last week, woohoo...2 days of internet before it randomly stopped working.
I then had to wait out the weekend, during which the English speaking helpline isn't available. I called the next Monday to find that the English speaking helpline doesn't deal with technical problems...boo. Had to ask my (amazing, amazing!) supervisor to call the Japanese one, felt so bad! After a long conversation, and I mean like 45 mins later, he explained that they'd exchange the modem...and here we are.
It's been working for an hour so far. Long may it continue..
