I successfully connected teensy 3.0 to the WIZ812 Adaptor Kit (edit: via breadboard, of course) and WIZ812 Ethernet Module!
I can use DHCP and ran several of the server examples.
There's a problem for now, and I'm still looking into it, but if somebody else has something to add, it would be good!
The problem is that it can't connect to websites, as in DnsWebClient. I don't know yet if it's not resolving the DNS or if it's another issue...
here's my results:
UPDATE: It's not resolving DNS names, I used IPAddress serverName2(74,125, 234, 243) for google and it went through! I'll check my DNS server now...
UPDATE 2: It was my DNS server (but it works on my win7 machine...) Now I'm using openDNS and it works...
