I got the impression that the router itself is actually mobile. While on base it connects to an 802.11b access point which somehow has access to the Internet. I think his second message implies that it goes to another router that has T1. I don't know if there's actually a wireless bridge link in the mix or what.
When in the field, he doesn't have that access. But he does have a satellite link. Anyway, I think he moves the router?? Which implies he disconnects the Ethernet that goes to the access point, so it is down. In that case, he doesn't need anything too fancy since routing out that interface will stop. The floating static route idea with the satellite link floating will work. I may have read too much into his statements about the router being mobile though.... :-) If he has the more normal problem that the Ethernet is up even though the wireless really isn't, then the solutions suggested below would be necessary.
