There are several possible reasons your connecting device is not obtaining a valid IP address:

• Reason: IPPT is enabled, and you have connected a second device to your router without restarting.
  When IP Passthrough (IPPT) is enabled, only the first device detected can obtain the IP address assigned by the mobile network.
  
  Solution: When IPPT is enabled, any time you switch the device you are connecting to the router, you must first disconnect the existing connected device and power cycle the router before connecting the new device.
• Reason: The DHCP server has been turned off.
  If IPPT is not enabled, the DHCP server provides IP addresses. If the DHCP server is turned off, no IP addresses can be provided.
  
  Solutions:
  Reset your router to factory settings, see Resetting your router.
  or
  Use Inseego Mobile LAN settings to turn the DHCP server on.
• Reason: The DHCP server has used all its IP addresses.
  This is unlikely to happen with the FX3100 series indoor router, but if you have connected a succession of devices to your router in a short period of time, you may have used up all the IP addresses available.
  
  Solution: Disconnect your connected device and power cycle the router before reconnecting a device.
• Reason: There is an issue with your router.
  
  Solution: Contact your service provider for assistance.
