Well, ain't this the darndest thing. My cable modem was acting up yesterday and not working at all, so I unplugged everything, let it sit for a couple minutes, then plugged it back in. Things came back on as normal and since then the connection hasn't dropped that I can remember, except for a few times last night when I was video chatting and then watching a show on Netflix online. I haven't been using the connection too heavily except for those times, so maybe that's the key? Who knows. I've got it running today but if it runs for a while and nothing happens, I start it over, hoping that the capture won't be too big that way.
