For those of you using the Actiontec routers from FiOS and can't activate home sharing try this: http://businessforums.verizon.net/t5/FiOS-Internet/iTunes-Home-Sharing-and-the-Actiontec-MI424WR/td-p/151123
Basically:
1. Log in to the routers
2. Go to Wireless Settings
3. Go to Advanced Security Settings
4. At the bottom of the Advanced screen, click on the link "Other Advanced Wireless Options"
5. On the Network selection pull-down switch from "Home/Office" to "Broadband" and apply
Neither myself nor the original poster knows what this does, but it fixed all of my headaches with all my PC's, Laptops and ATV2 that couldn't find a darn thing.
