I have a aspire 4520 with windows 7. When I connect the laptop to a router using an ethernet cable I am able to get on the internet. When the cable is disconnected, there is an x on the wireless connection and it is no longer available. My question is, Is there a way to connect to the internet without having to use the ethernet wire and if so what steps do I need to take? I have tried all the suggestions already provided and nothing works.
