Do you have the RH box set up to route traffic for the wireless IP?
ip address add 10.0.1.38 dev eth0
(replace eth0 with whatever the device for the wired interface is).
You could also just bridge everything from the wired interface to the
wireless interface although I would strongly recommend against it from
both a security standpoint as well as a bandwidth standpoint especially
if you have any real traffic on the wired interface.
