Thanks
I think you may only be able to use ICS with an internal modem.
If you're thinking of going wireless and buying a wireless access point for
it then maybe think of buying an external wireless modem/router and dumping
the internal modem. There's not much price difference.
If you don't have the pennies then you can use ICS, dont buy an access point
and set up AdHoc mode with your wireless network cards. Don't think Id
recommend this unless you're confident with networking.
