on the old DLM thresholds of 2880 ES/day that line will be interleaved within 2 days. Also the SES isnt pretty reading.

This is on the assumption the uptime is under 12 hours at the time of the post.

That was with 4 hours uptime.

My line is definitely not fine.

Take a look at the QLN and SNRM graphs for instance:

Could we see the current stats please?

Also are you using an unlocked HG612? If so then xdslcmd info --pbParams as well.

Re: Got FTTC today, stats aren't looking too good?

[re: deleted] [link to this post]

Only time for a quick glance. Two comments.

First you now have interleaving turned on. That typically costs around 10Mbps of Bearer 0 Downstream. But you've lost more than that.

Second, I'm surprised you have lost the complete top band of downstream in the medley phase of pbParams. That's the line showing what you are using as opposed to the discovery phase which just gives what is possibly available.

There are several others who know more, but it might be an idea to see what you get when going right back to basics. Which would be removing the faceplate and the VDSL filter plate and connecting using a dangly filter into the test socket.

If that's still bad then we need to start thinking of possible causes. If it's good, we have established something is dodgy on your premises.

I assume the whole lot isn't behind a TV or on top of/very close to something else electrical.

I've previously tried it through the test socket and it made no difference but I'll be happy to try again?

On Plusnet you can't tell the difference from speed tests, at least not until a few hours later. Only those two sets of stats.
