I did down modem stats the other day,

Note that both the pictures I've linked you are from the other day and speeds have dropped further er since then,

I will see if I can pull some more stats later.

These are what I pulled from the modem the other day

The fact that i'm seeing inconsistent and unstable speeds and that streams keep stopping randomly and that I have to intermittently refresh webpages 2/3 times for they load successfully.

Some of those issues could indicate a problem - especially if they see any re-syncs happening.

I also noted that in my experience Interleaving isn't normally applied at such a high rate straight away and that it normally staggers until errors stop but in this case that didn't seem to happen.

From what I've seen, which isn't enough yet, interleaving hasn't intervened in a particularly high rate. It looks quite standard so far...

In reply to a post by BatBoy:

Unfortunately the attenuation isn't shown, but there is a large gap between sync speed and attainable speed.

That's normal for the HG612 when DLM has intervened to put FEC and interleaving on; while the sync speed drops, the attainable goes up by a similar amount.

That often indicates a fault.

Right. A monitoring programme would certainly help to see changes as and when they happen.

It would help to see a few things lower down, particularly the INP and delay values.

The amount of FEC overhead downstream is 20%, which isn't especially high. However, you have a lot of FEC overhead upstream, alongside interleaving.

That suggests you are getting delays on both upstream and downstream, which would be affecting latency even more. Seeing the INP and delay settings will help to understand what DLM has asked for.

What would be really worthwhile is to monitor the changes to INP and delay over time - to see if DLM is making changes; DLM normally responds to resyncs and errors - so it would be good to see those over time too. I'd definitely recommend one of those monitoring setups.

What does?

I don't think a jump of 16ms on my BQM is normal after fault free since connection on fast path.

The post I replied to, obviously.

So you agree that some of the settings on the connection need changing or resetting, as you said, interleaving has been set on both downstream and upstream with a delay of 8 (I saw in modem stats)

and if I'm right, your saying that if their is any fault it is on upstream and not downstream..

Here is my modem stats before the issues!

58-59mbps download 17-18mbps upload and 11ms ping (rapidswitch, Maidenhead)

I've ulled the stats from my modem using telnet, they're as follows!
