Sharing 3G-connection to desktop

[jiopsi]

Setup:

X60 XP laptop 3G (with mobile broadband) -> WLAN-connection to wireless accespoint
Windows7 desktop -> RJ45 connection to wireless accespoint

Now I have enabled ICS from 3G properties, but desktop can't access internet. Can somebody help me?

Thanks, this was the essential step that helped:

- You will have to disconnect and reconnect your 5220 card for the changes to take effect.
