help with Uthernet

[Nama <forums6000@mac.com>]

Hi everyone,
I've finally given up and resorted to posting here.
I have an Uthernet card in slot 4 of my Apple II. I am wanting to use Contiki. I have the Uthernet card connoted to hub and that hub connects to an Apple Macintosh mac book that is sharing it's wireless network through the ethernet port. 

I have tested that the sharing is working by connecting another Mac to the hub. 

I used to have a similar setup working about 3 years ago before the Apple had to go into storage. Now I'm at a new place with a new network and new macbook and I can't figure out how I used to have it working. I think I have spent 3 hours putting in various IP, gateway, DNS and Netmask addresses...but nothing seems to work.

The other Macintosh that I used to test the shared network was showing the following under it's network preferences:

IPv4: 192.168.2.2
Subnet Mask: 255.255.255.0
Router: 192.168.2.1
DNS:  192.168.2.1

...so I would had thought that the Contiki/Uthernet setting would have been similar:
IP: 192.168.2.3
Netmask: 255.255.255.0
Gateway: 192.168.2.1
DNS: 192.168.2.1

...but that didn't work.

Would someone be willing to hold my hand and help me find the correct numbers?

Much thanks in advance.

Phil
