When changing the UID:"lan" VLAN interface to a WAN port will remove administrative access to the Cradlepoint if step 2 through step 4 were not followed. The IP address to access the Cradlepoint has changed when following the above steps and you will need to navigate to https://192.168.10.1 to access the administrative pages. If you still are not able to access the Cradlepoint you will probably have to factory reset the device.
