Ok then,

Provided when your Classic II is connected to the router:

1). The gateway address shown is the same as on your Macbook

2). The DNS address(es) shown is the same as on your Macbook

3). The IP address for your Classic II has the same first three numbers, and a unique last number

You should be connected to the internet, and your local network for IP.

An older Netscape or similar browser should work - but be aware that they are old and will have significant problems with current webpages. You should be able to do FTP easily enough though.
