From your post it appears you have not attached an ethernet cable to the card, the result would yield a cable unplugged notice. If you have attached one then either the cable or the ethernet port on the modem can be bad.
I use an Actiontec Gateway to access the internet via Quest DSL. Currently it is attached to an USB port. However, the preferred set up uses ethernet. Unfortunately, the Gateway can not see my ethernet device-a Marvell Yukon Gigabit with an August 2004 driver. I checked the device manager, the ethernet is there and (apparently) in working order.
However, in "Network Connections" the Local Area Connection reads "network cable unplugged." I assume this refers to the ethernet connection? Where is this network cable. Do I need to delve into the innards of my new computer?
Naturally all this occurred on a weekend. No one has returned my phone calls. I can wait til Monday, but if there is a quick fix....
