I've got 100/20 broadband and I think that's probably OK for our current usage.  However, some services, e.g. Netflix, auto throttle when bandwidth isn't sufficient, so this could potentially happen without us knowing it.  Is there a way on an Edgerouter Lite to monitor WAN bandwidth usage and see if it is in fact getting saturated at any point?  Or even just to stress test with a couple of 4K streams and file down load or suchlike and observe the useage.
