Network connection/adapter disappears when disconnected, I have gone into the adapter and turned off the power saving mode. This is a new laptop using Windows 7 preinstalled.

Does this provide any assistance?Control panel---classic view-- taskbar and start menu---Notification area tab--System icons. Is the network option unchecked? Otherwise, check it and apply. John

Hi,You can try John's suggestions first. If the issue persists, I suggest you upgrade the NIC driver to latest one for a test. Then, please click Start menu and type "ncpa.cpl" (without quoation mark) in Open box, and press Enter. Does the "Local Area Connection" icon list in the window?Thanks,Novak
