hi, i a little confused about wan circuit throughput.
I have a 1811 as a border router, currntly this router has 4 wan conecctions. 30/10 , 20/20 , 12/6 and 20/20 Mbps.
and it has also 12 vpn ipsec vpn active.
the router works fine with 20% of cp...
i had the same issue.
watch your line configuration.
line 3
dialer script gsm
i had to change it for dialer script lte
i have been working with a 819 router last days, copy your running config and may be i can help you.
