Mike, my adapter for 'local area network' is set exactly as your example. I also have a 'dialup' adapter that I use for a back up internet source. It has the same TCP/IP configuration, but other options such as 'client for Micrsoft Network' and 'file and printer sharing are not 'checkmarked' (they are checked for the Lan adapter)
To clarify: I use the Lan adapter to access the internet from my network. I use the dial-up adapter if my Direcway Sattelite is down for some reason.
