In an odd bit of synchonicity, I was also having computer problems. Over the past month, my ability to connect to the internet on this computer had been getting increasingly spotty. Three days ago, I lost connectivity altogether.
I had been having other problems with my computer as well, but I could not continue to work on this computer without connectivity (my ability to update webpages for my clients was particularly difficult to do without it).
So I finally bit the bullet and reformatted my machine.
Which completely failed to solve my connectivity problem. Grrrrr...
I finally narrowed down my problem to my ethernet port (not a card b/c it is built right on to my motherboard). So I disabled it in my hardware profile and threw a new ethernet card in. Finally I'm back up and running.
