Hello,
For some time now we have been experiencing an issue on the network for a while. I haven't been able to figure it out.
When downloading a large file (usually 500 mb or higher) the download starts strong, then slows down, coming to a complete stop eventually. I've tested this at the router by plugging a laptop directly into our router. The download is fine there. But from the router, it goes downstream to our ASA then to our Core Switch. I tried the download directly out of the Core Switch as well and it seems like the problem starts when I am in the internal part of the network (ASA and downstream). I have been looking into QoS as other engineers have suggested. I am the only Network Engineer and I've been stuck on this problem for a while now. Can anyone please provide some insight to what may be happening on our network?
