I have a w7 Desktop and I use google chrome for my internet browsing. The problem that I have is sometimes randomly, my wireless disconnects. The w7 pc is not connected to the router through a wire though, because another pc in my home is already. And when it disconnects, the wireless icon remains with bars but i can't reach any sites on my pc. And also after a few seconds of disconnection, the yellow triangle with an exclamation pops up on the icon for a few seconds and dissapears. I've tried a lot of things but it still hasn't been fixed. Will someone help me?
