Claim 0:
1. A network management system comprising:
a memory storing path data received from a plurality of network devices operating as network gateways for an enterprise network, the path data collected by each network device of the plurality of network devices for one or more logical paths of a physical interface from the given network device over a wide area network (WAN); and
one or more processors coupled to the memory and configured to:
determine, based at least in part on the path data, a wireless signal quality of a logical path within a specified time window and a link quality of the logical path within the specified time window;
determine that the logical path is of a poor link quality during the specified time window based at least in part on comparing a count of instances of poor link quality during the specified time window to a poor link quality threshold;
determine that the logical path is of a poor wireless quality during the specified time window based at least in part on comparing a count of instances of poor wireless quality during the specified time window to a poor wireless signal quality threshold;
in response to determining that the logical path is of the poor link quality during the specified time window, determine a correlation between the poor wireless quality of the logical path during the specified time window and the poor link quality of the logical path; and
in response to determining the correlation between the poor wireless quality of the logical path during the specified time window and the poor link quality of the logical path, output a notification that identifies the correlation between the poor wireless quality of the logical path and the poor link quality of the logical path.
