Replacing the Network Card on a Toshiba S855-S5254
Generally I've had very good luck with Toshiba laptops. They don't offer much in the way of fancy bells and whistles, but they don't come with high prices, either, and I'm good with that. Unfortunately, this latest one I have, the S855-S5254, has really had some issues with wireless network connectivity recently.
As I tend not to think it's the laptop, I've been racking my brain trying to figure out the problem. Our cable was cut, so I have been on the phone with Time Warner trying to see if they would come out and check it (they won't, they already came out and re-buried the line). So I bought a new D-Link router, and a Netgear one, to replace the venerable Apple Airport that we have. After spending who knows how long trying to get things reconfigured, and watching the time graph of inSSIDer on multiple devices, it seems the problem is the laptop. Wonderful.
