Line not syncing on the correct speed

Question

I have a 10Meg line but was sycning stably at 6Meg, until the morning and my internet was not stable and dropping often, but once everyone started to leave the building the line became more stable.

What could possibly be the cause?

Answer 1

The line stability could be caused by congestion at the exchange you are connected, line copper quality, the distance you are from the exchange and the quality of the equipment that you use to connect to the internet.
