Sprint TP2 - Static IP for LAN?

[jj14x]

Hi,
I got the Sprint Touch Pro 2 and must say that I love it so far. Just a couple of small issues that I hope somebody here can help me with.

The EVDO works fine, but for my wifi access, I need to get a static IP assigned. I had a mogul earlier and it worked find - I just went into the network adapter and configured the static IP and the DNS. When I tried to do this on the TP2, my wifi would work, but my EVDO would stop working. I suspect I'm not updating the static IP on the correct network adapter.
Has anyone else tried this and gotten this to work?

Any pointers would be appreciated.
Thanks!
