That is kind of expected, because you need integration for that to happen (when coming out of IDLE mode, a DHCP renegotiation has to happen) -- this is something that is currently not integrated. If using network manager, you can use the applet to re-select the WiMAX connection to renegotiate a DHCP address. That will make it go through again.
