In the past few weeks I have been having internet problems. I am always able to log on to the internet without any problems after starting my computer. However, if I stay too long on a page or if I am idle more than a few minutes I am kicked off of the internet and I cannot reconnect. When this happens and I go into network connections the network light is always yellow instead of green. The only way I've found to reconnect is to restart my computer. What is going on?
