I am trying to connect my second Acer 3680 laptop on the network. It has Windows Vista basic in it. There is a active wireless connection available but somehow it is not able to work. There is a D-Link router configured on the network. It is a public network. There is not password protection. When I had connected the first laptop that is the same model it worked. The problem only lies with the second laptop. All in all there are around 3 laptop connected on the network. Two are working and the single one is only that is loosing connection. I am not sure about the problem, but it looks like some kind of hardware fault. In the laptop we cannot even put a lan card to fix the issue.
