I have an Acer laptop with Windows Vista Premium. Recently I've been having trouble with my Netgear router (WGR614). When I connect wirelessly it usually connects fine, for the past few days it's been coming up as an Unidentified network and it has not been giving me access to the internet, (local only). Below is a screenshot of when it's working fine (GREEN) and when its not (ORANGE) why does it do this???
