Hmmm...

Changed anything your end?

I wonder if the Manchester City v United match yesterday evening had anything to do with it?

I had upgraded my router to the latest firmware but RobertoS has spotted the obvious issue in that the x1 &x6 bear no resemblance.

Reminds me of this thread on the Plusnet forum (my 1st comments are on page 2.)

So if things stay good at peak time suggests router firmware was limiting you for some reason.

I didn't expect this

But you provide 6 streams. 201.8 / 6 = 33.6Mbps per stream. Which is still unacceptable.

In fact that makes it worse, as 201.8 /8 = 25.2Mbps per stream.

Doesn't that make it better rather than worse, because 25.2 is closer to the 12.3 quoted than 33.6?

No. Because 25.2Mbps throughput is further from the 200Mbps sync than is 33.6Mbps.

Bear in mind what MrSaffron says, and he has the figures to back it up, that when presented with multiple demanding streams for the same line the ISP (or Daisy Wholesale in this case) might step up the "per stream" throughput allowed.

The single stream 12.3Mbps is exactly what it says. In my opinion probably representing a single-stream limit of 15Mbps or 20Mbps.

And remember they changed firmware on their router and things have improved.

"The single stream 12.3Mbps is exactly what it says. In my opinion probably representing a single-stream limit of 15Mbps or 20Mbps."

If there is something limiting to 15 or 20 Mbps, then I would expect the throughput to be a lot closer to the 15 or 20 Mbps.

And remember they changed firmware on their router and things have improved.

And then went back down to the low levels that same evening so it appears it was coincidence the speeds increased for a half a day.
