I stopped by Best Buy after work today because we thought there might be something wrong with the wireless network card. While I was staying with my brother I wasn't able to pick up the three or four wireless signals in his building, including his. We knew that it had worked at my dad's house at the beginning of November, and logically came to the conclusion that something had damaged the card.
When I got to Best Buy the guy asked me where the switch was. I looked at him blankly. "There's a physical switch?" I asked. He tilted the laptop up and sure enough, there's a flat button under the front lip (he had to look for it too). Lo and behold, it was then able to connect to the store's wireless network.
Man did I feel stupid. I'm sure I was very red-faced. The told me not to feel bad, but I still did. I've been trying to figure this out for six weeks. I must have missed that in the owner's manual. Or assumed that they were talking about the light that goes on when the wireless connection is open.
I'm going to go hang my head in shame until the girl arrives to look at the apartment.
