Brand new, straight out of the box, Emachines desktop model EL185-01e. I have a wireless Netgear router that works perfectly on any other computer. When I try to connect to the internet on my new computer, it says "No connections are available." and when I open up the network and sharing center and click on Connect to network, it just takes me back to the "no connections are available". It wants me to connect an ethernet cable into it but I want to use the wireless internet.
