Holdposition,
Now that you have AOL B/B at work, have AOL B/B put in at home too. Then you can plug in at either location and the notebook will just work, instant internet.
When you are ready to add more computers then we just add in routers at each location and you get the added protection of a hardware firewall along with multiple computers all wired together in a network. (But more on that when you are ready to make that leap.)
Take Care,
Richard
