Yesterday, we got keys to the department and our office. I went to check and make sure mine worked. I didn't think the key to the office was working. I tried and tried and it wouldn't open the door. Turns out, I was turning it the wrong way.
Today, with my grand ambitions to go sit outside and work, I walked down to a cafe on University, only to find that there were no wireless networks available (or so I thought). So I went to the student union, where I knew there was wireless access and encountered the same problem. I just now realized: I had the wireless turned off on the computer. Doh!
