I have a mysterious problem with my Internet connection. The Edge topology is in the attachment so are the most important "show" commands. We have a 50Mb/s symmetric Internet connection. When we use Internet through ASA the download speed does not exceed 3Mb/s whereas the upstream is at about 45Mb/s. When we connect our LAN directly to 2960 the downstream increases dramatically up to 47Mb/s whereas the upstream remains at about 45Mb/s. Duplex is manually set to 1000/full on all interfaces. All that I have noticed are dropped packets on outside interface (Gi0/0). The reason is unclear. Could that be the reason for speed degradation?
What could be the problem?
Any help is appreciated!
