I understand.
If you want the laptop that's connected to your external antenna to
connect wirelessly to your second laptop, then that first laptop needs
*two* wireless adapters. If it has a built-in wireless adapter (in
addition to the USB adapter), you can use that as the second wireless
adapter. Or, as Jack suggests, you can buy a second USB adapter.
Altogether, you need a minimum of 3 wireless adapters: two on the "main"
or "host" laptop and one on the "client" laptop.
All I meant by the comment at the end of my previous post was that if I
were you, I'd bring a long Ethernet cross-over cable along so that if
your laptop-to-laptop wireless link doesn't work, you can use ICS via
the cable to get your second laptop connected.
As with a lot of wireless networking, you probably will have to do some
experimenting. For example, although I mentioned possible interference
between the link to the campground router and the ICS link to the other
laptop, it may well be that with your external antenna outside of your
metal RV, you won't get that interference.
