Problem Solved! :)
Found a way to use an old ADSL DLINK router with the USB modem (3G stick + Internet Connection Sharing + Windows 7).
1. Set up ICS on the computer with the USB stick. Share it. (ICS Default = 192.168.0.1 and 255.255.255.0)
2. Set up the router with DHCP and NAT disabled and a fixed IP in the same range, like 192.168.0.99 and the mask 255.255.255.0
3. Connect the rest of your household computers to the router network.
Tip: Set the "Default Gateways" to the router IP (192.168.0.99) to avoid the network showing up as an "Unidentified Network"
