Well I rebooted the rooter today at 4.00am, and the result was exactly the same as when I do between 10am & 2pm.

Thanks reporting back
It seems the firmware code you have is giving all ready the best your current line get
You also may be near exchange as mentioned up

I also getting some reboots and up to 3 mb less sometimes so is like So you hate it or you love it

You can see my test here (status pages screen shot) how some time will synchronise with lower speeds like your case but i don't think is a fault of the draytek
