I have been experiencing some rather tedious speed drops in recent days, and when I called the support centre, it was put down to congestion.
My question is this...
How do you plan to fix this? If you can't even keep a reasonable 50mbps steady, why even sell 100mbps?
It is likely that Voda is packet shaping during peak times to limit your download speed. Change to someone like Orcon, who don't do this. You will get the fastest the network can go, 100% of the time.
