To me it sounds more like a routing issue within the upstream network and not an issue which will be located in your property.


In my experience of using cable bb the issues mainly with dropouts are if there's either some larger issue network wise (like the time the other week when allegedly some scallies cut cables at the VM network centre at Colwick and basically meant that the modems didn't lose sync with VM but that VM's entire network dropped off the rest of the world) or that the local signal levels aren't right which a tech can see easily with a signal test.



As a total aside have you checked or tried to increase the FTP timeout as sometimes the FTP daemons on servers time out during a transfer as they don't count an ongoing transfer as actually connected, and thus will disconnect the client as inactive?
