Hard so say for sure, but maybe it's the incorrect device driver you've got.
Note that the ariadne.device between the Ariadne 1 & 2 is NOT compatible between
the cards.
Send me your email addr and I'll DMS you an image of my Ariadne 1 install disk.
As for using AmiTCP/Genesis, it will work, but the setup is a bit more fiddly
than Miami, which I'm more familiar with.
Once you can correctly ping each machine's IP address, you need to enter each IP
address along with host hames into the host name database of AmiTCP/Miami.
Then you should be able to "ping Mac1" for example, and it should work.
If you want to share files, printers, etc; you'll need to install Samba, a
network file system. That's a whole different process though, I won't go into
it right here
