Ok a little bit ago I went over to my friends house who is using Windows Vista, and they wanted firefox on there computer. So I downloaded it on there and everything worked fine. Later that night the internet went out completely. Now I work for Comcast HSI so I figured this wouldn't be dificult at all. I powercycled the modem, checked for proxies, made sure the tcpip was obtained automatically, release/renewed the ip. After all this, still wasn't working. So I turned of the computer completely for about 1 minute or two unplugged the modem then plugged it back in before rebooting the computer, and it worked, but only briefly. I was surfing fine, then I closed the browser and reopened it and it was back to where I started. I'm kind of clueless with this windows vista and I personally think it's a piss-poor OS. So anyways, if anyone has any tips I'd greatly appreciate it.
