bikerdev,
I had a similar problem, I ended up just turning off my MAC authentication, connecting, getting my MAC then turning the authentication back on. Another thing you could do is setup something like what another fella said he did for war walking. Go setup a network to connect to, set it\'s type (in the config tab) to Ad hoc and give it some dummy IP address, subnet, and gateway. Then connect to it, you should now see your MAC in the \"Current\" tab in networking.
