Traffic Shaping

If the traffic shaping wizard was run previously before an increase in upstream bandwidth, the old limits may still be in effect. Visit Firewall > Traffic Shaper and check the root interface queues, and qInternet queues to ensure that any listed interface bandwidths are appropriately specified and current.

Also check the Limiters tab under the traffic shaper settings, verify that any configured limiters are set for appropriate speeds. Limiters may also need increased queue lengths to handle higher throughput volumes.
