We have three new wAP devices with LTE using 7.8 and all three sims are working and connecting to AT&T but it seems that no traffic is flowing though it. I setup a SSTP client which it connects while its on ethernet but when I disconnect it from ethernet it doesn't connect.
I believe that it is not failing over to LTE when I disconnect because I did a traceroute on the LTE and its working.
Any suggestions on how to fix this?
