We have an IMB Think Pad and it is connected to our internet through a router and we use the D-Link AirPlus G Wireless Utility Card. When we go on vacation and take the laptop with us, will it connect to the internet at places that offer free internet service? There is another card that came with the laptop, so would we use that one instead? I know, sort of a dumb question, but I need to knwo before we leave.Thanks!
