Last Sunday I had a day full of connection drops, where the connection would keep dying every so often and losing sync.
As a result, my 16 megabit connection download speed is now just over a quarter of that, stuck at 6 megabits - in the intervening period, the speed had fluctuated between 1 megabit and 8 megabits for the past few days. It's the same with uploads - it was originally 1 megabit and is now back to that, but it has fluctuated wildly and at its lowest was a paltry 370kbps.
How can I make it go back up to its usual speed? And what would cause such a sudden increase/decrease?
