Every so often when I use my computer, I have my cable connection shared over a Netgear MR814 Wireless router. My computer is wired to it. Occasionally, the internet connection to my computer stops suddenly without warning. I have to unplug the power and replug it for the internet connection to work again. Is there any way to prevent this? It's really annoying when it happens when I'm in the middle of something, such as a download.
