The sync speed is not set by Virgin. It is negotiated between the router and the equipment at the telephone exchange. Repeated router re-boots can fritz the process by making it look like there's a line fault, resulting in a lower sync speed, but if that had occurred it would only take a few days of *not* rebooting the router for the sync speed to climb back up again.

In the absence of any other information, it seems that Kursk's sync speed appears quite happy and stable at 2854, which suggests the rate-adaptive ADSL has done exactly what it's supposed to do and has established the fastest stable speed for the line.

Improving that speed any further will require the imperfections in the line, wherever they are, to be found and addressed.
