With the last two firmware releases on the Vigor 3900 I am getting really poor upload performance. QOS is disabled. I had a similar problem on my vigor 2850 and I ended up resolving this by setting the QOS to on and setting it all up to give 1% to the three classes and 97% to other. Is QOS doing something still in the background? The 3900 is connected to 2 DSL lines via Draytek 120 modems. It is litterally taking ages to upload 2MB. Interestingly enough, if I go outside the network onto a hosted machine (the same machine im uploading to) and then transfer a file its loads quicker. for example

Internal network scp a file to remote server = slow

remote network scp a file from local network = lots better.
