Thanks Gord! I'll look him up when we are over there.
Thanks to everyone else for their suggestions. Beach Cruiser - we'll keep a look out for you. We're at Guana today but we will be in the area for the next couple months.
The problem is that I may have inadvertently bought a computer without a wifi card in it. Its a spare computer that's been sitting on the boat for about 6 months. The wifi on the boat works great, its just this computer doesn't seem to have a way to connect. If that's the problem, something like this
will easily fix it. Available at any Wal-Mart and hopefully somewhere in the Abacos too.
