|"If my pc is connected to an external modem, why does my computer tell me that the yukon marvell is my modem?"|
Confusion in the word "modem" There are two types of modems, one for phone lines as in dial up and one as in dsl/cable which is broadband.

Don't uninstall your dialup modem or your network interface. They are normal so quite worrring about them.
Answers are only as good as the information you provide.
