Upload speeds cut by half...again, another SNR reset?

[#1]

Plusnet guys any advise please?

[#2]

Having had a look at your line, all the tests are passing as the speeds you are getting are within reasonable limits.
Unfortunately there's no guarantee on upload speeds, which is another reason why the tests aren't showing any problems. We don't have any grounds to get engineers out to investigate the issue for the above reasons.
I can't see Interleaving on, so it's not that causing the problem. There may be something causing interference on your line which is causing your upload speeds to drop. The only thing we have in our power to do, is an SNR Reset, but that is likely to do what has happened previously, again.
You are, of course, free to raise a fault with us at http://faults.plus.net however we may find the line is within BT's expectations.

What about switching interleaving on? Then most of the errors might be corrected and the DLM wouldn't then increase the SNR margin.

We could do that, I would expect upload speeds typically between 500-888Kb.
If the OP is happy for me to give that a go I'd be happy to, however, applying Interleaving would apply it to both the up and downstream.

The OP is more than happy for you to give it a go Chris :), 500-888Kb on upload sounds great aspecially when Im on 300-400Kb at the moment.
Go for it!
@ejs thanks for your input.

That's been placed for you, it will complete tomorrow. Let us know how you get on.

All looks good now, even upload speds went up a bit,
hope it will stay like this
thanks Chris
