I'm using Windows 7 64bit with a D-link DWA 130 wireless N rev c1 USB nic and a D-link DIR 615 router, When I have the settings on the router of either wireless N or N&G the connection drops every few minutes, When it's just G I have a constant connection but alas the connection speed fluctuates at 48 to 24 Mps. Does anyone know why wireless N drops? is it the router and/or the nic?
