Hello, I just moved outside of the city and we do not have DSL/Cable internet available. We went with hi speed sat. internet and it is terrible. I am going to cancel and go with either the USB data modem that Sprint has or the ATT pci express modem. I doubt they will be faster, but, at least they cost less and I can take them with me on business trips. My question is this. Currently, I use internet sharing and use my mac as a 'base station' so my kids can play games on nick jr. on their mac mini. However, the options for internet sharing do not list USB/PCI express as an option. Will it work, or does my main mac need to be connected to the web via an ethernet connection in order to share its internet?
