My internet will stop working all of a sudden and when I troubleshoot the problem, it tells me to restart my "wireless internet connection" adapter. It does this about every couple hours... So, I look and see that it is disabled and I enable it but it just sits there FOREVER and doesn't do anything. I have to shut down the computer. The computer doesn't shut down and sits on the screen that says "shutting down...". So then I have to force it, which I hate doing! What is going on?
