DC112A Smart Cradle Solid Amber Light Internet Connection

I have a DC112A Smart Cradle on firmware 1.0.0.30 with a 781S AirCard connected to it. When it is first turned on everything works fine. After a few hours a solid amber light turns on under the Internet Connection symbol. When this happens I lose all internet connection. The AirCard never looses connection to the AT&T network. It always shows a full signal. If I unplug the AirCard from the Smart Cradle and restart it then plug it back in the internet connection lights up green and starts working again. This is really becoming a problem because I can't access my Smart Door Lock and Video Doorbell when I am not at home because the network connection goes offline. If anyone has any suggestions please let me know. Thanks!
