Tmobile internet backup as failover
I have Unifi UCG Ultra and wanting backup cellular internet. I got the tmobile home backup and connected lan 1 to my ultra. I have failover setup properly on the unifi. The problem I have is getting tmobiles auto-connection working properly as I think tmobile and unifi are trying to attempt the failover. The auto connection finally worked but its staying on all the time and using my backup minutes instead of staying off and turning on when unifi tells it. Is there some setting in Unifi? Or how is everyone using this properly?
