Rak2013-default to active wifi if available

Just wondering if anyone has successfully configured the RAK2013 LTE hat to be used as a back up when another active internet connection is available. I currently have a pi using the latest images and fully updated. The wifi is connected and has an IP but all internet is directed over the ppp0 interface. If I stop the rak-pppd service then the wifi is not able to find the network even though it is connected. A ping to returns network is not reachable. I’m able to ssh locally through the wifi but nothing else.

Any ideas? I can send route info or other info if that will help.

Thank you.
