Which points towards there being a big burst of errors on the line. Hence why its not so much the speed test that is important, but your line stats and those error counters.

Each error means it takes more bandwidth to get the useful bit of data to you, and so you could be wasting lots of bandwidth handling errors.

I wish you worked for EE, we would of had this sorted by now.

This is the stats after the last re-sync just short of 20 hours ago.
Don't know if there is anything in the stats that look a bit 'iffy'?

Also the router was last cleared of errors about 23.30 on Saturday 6th.

30 million packets that interleaving corrected due to errors, high.
17 loss of signal - higher than average.
13700 errored seconds, or around every 18 seconds you get a second when router is logging an error.

Personally I'd expect you to be on a 9dB target margin to reduce the load on the line and probably reduce number of errors.

That would probably lower your sync to 14 Meg, but might improve stability

Please check the OP's other thread http://forums.thinkbroadband.com/general/f/4226118-d... on 07-04-13 a ~9dB SNRM didn't really help with the error rates after being connected for approx 8 hours:

In which case it might need a 12 or 15dB margin.

Thanks for your post and the breakdown on the errors. I've just had a re-sync now as I was on the phone to EE and the NM is still at 6bB.

Router is on its way - so I'm hoping we can rule this out soon
Thanks again.

I think he had that when quoting stats in the opening post in the other thread:

Thank you for finding these stats and for your help. It's appreciated

So what was the problem when you had the sync speed of around 9.7Meg, by running faster now it will certainly not help.

You appear to have a noise issue, and by running at higher sync speeds it is more evident. Reason for the noise issue is unknown.

If the line was performing as expected for a 9.7Meg sync like you had originally, then Orange are within rights to return you to that setting and say it works. There is no requirement for them to provide a certain speed on a certain length of line.

If the line was resyncing a lot with the 15dB margin, then a SFI visit to try and figure out the noise source, be it an issue with the copper line, your wiring, or an electrically noise device nearby is probably the way to go.

Allow me to introduce you to another EE user on a similar connection who is also suffering from high error rates: http://forums.thinkbroadband.com/freeserve/f/4223506...
