I'm using W7 on the machine that is supposed to share the broadband connection. Then I have tried both with my laptop (Windows Pro XP SP3) and my mobile (Symbian). I still suspect it's the IP assignment on the host machine though, as somehow recreating the network each time always work, but by simply using a saved network say next day, will let me reach the host but the internet connection sharing is not working. Manually doing the IP assignment might work... will have to try that.
I had the same problem.
This is the solution I implemented.
1) Open Network and Sharing Center
2) Go to Change Adapter Settings
3) Find the adapter for the default internet connection (it was a PPPOE in my case)
4) Right click on that -> Cancel as Default Connection
4) Right click -> Properties -> Sharing tab
5) Uncheck "Allow other network users to connect ..." if it is not
6) Setup the ad-hoc as cocaine explained in the previous post, the Turn on Internet connection sharing should appear
Hope it works for you
If you don't see the button "Turn on Internet Connection Sharing", that mean the ICS is turned on before.
To see the Button again:
- go to the Network an Sharing Center >Manage Network Connections,
- Right click on the Wireless Adapter chose Propertise
- In the Sharing tab, uncheck the box "Allow other network users connect...." then Click OK.(Sometime I don't see the Sharing tab, I don't khow why , but when I Uninstall/Reinstall the Wireless driver, it appears)
- Recreat new Ad-hoc and you'll the button "Turn on Internet Connection Sharing" again
