Trying to connect up a HG612 and router to view more stats but not going to plan to view wirelessly using wan cable only. Watch this space

There are a variety of guides here - https://kitz.co.uk/routers/hg612unlock.htm#bridge

Can't make head nor tail of it. I was hoping there was a method without using command line prompts

[rugby675]

Scrub that, got it working now over WAN cable, didn't need command prompt afterwards. Let's see if I can start collecting some stats on my extension and then compare to master socket in a few days. May reveal that my internal wiring is shoddy

[rugby675]

Interleaved depth is 1263 which is bad I gather. Does this number reduce over time with a stable connection eventually reaching 1 where interleaving is eliminated? A few FEC errors present but not much else

[g3uiss]

No not really, what is delay 8ms ? I think that’s medium interleave. I think your latency problems are elsewhere. Have you done a tracert to say bbc.co.uk to see where it is ?

It doesn’t gradually go down, it may reduce after a DLM initiated resync to a lower figure but not go to 1 until the DLM removes it, which seems unlikely

[rugby675]

Connection seems very stable now, no disconnects or resyncs. Aside from me manually switching over yesterday previous connection time was 12 days.

Is there a way to force interleaving to be removed by manually capping speed? Tried to telnet last night but doesn't seem to like it as I have changed the IP of the HG612 so I can access remotely, I will address this first. Latency using an ethernet cable is approx 16 ms, a lot higher using wireless, a lot higher.

... Latency using an ethernet cable is approx 16 ms, a lot higher using wireless, a lot higher.

As @g3uiss suggests I'd say the core issue is not your FTTC connection at all as 16ms latency (how are you measuring this?) on ethernet sounds like you just have the base interleaving delay you'd expect on an ECI cabinet.
On my Huawei connection (not interleaved) I see ping times to www.bbc.co.uk of between 10 and 15ms on wireless so you shouldn't be seeing more than 20ms or so for the same test.

Interleaved depth is 1263 which is bad I gather.

Not really.
The depth is higher on lines with a higher sync and vice versa.
That looks very much like Low Interleaving.

There is a stat called delay that tells you exactly how much added latency (delay) there is on the line. It will be delay: 8 which is the lowest the DLM can add.

Wireless will usually have a higher latency compared to wired Ethernet. That's nothing to do with interleaving though. Low interleaving will add exactly 8ms to the lines latency no matter what you are doing over the line.

[rugby675]

Found it, confirmed 8ms. Suppose it's not that big a deal but running devices on ethernet isn't practical currently with cables running everywhere. The question is what can I do about it. Strange that it appeared that the 8ms was removed almost instantly when I removed unnecessary extensions a few weeks ago but then came back :s doesn't seem to be any errors on the line

[tubaman]

I think you need to be looking at why you are getting such large latency over wireless rather than worrying about the 8ms interleaving delay. As you have found already you can take steps to get rid of it but DLM will likely put it back again unless you are prepared to permanently cap the speed to keep the error rates down.

[rugby675]

In the last 18 hours has 1 ES error on the downstream but 20000 on the upstream would that be sufficient to apply interleaving to the down or do the two work independently?

[g3uiss]

Independently.

I really think you have issues much more significant than interleaving.

A large proportion of lines always have interleave with no problem

[tubaman]

20,000 ES in 18 hours is a crazy amount and should be causing far more severe action from DLM than just interleaving. Where have you got that figure from as the GUI stats in the HG612 are all over the place - best to use the CLI to get them.

[j0hn]

20,000 in 18 hours is nearly 1 ES every 3 seconds, a very very high figure.

Just to note that some Lantiq chipsets show historical ES numbers (weeks/months worth) not just since sync.

What modem is that with?

[rugby675]

20000 is on the upstream and obtained from telnet on a Hg612 also confirmed by DSL stats. The upstream stats are odd all round imo where sync speed is 20 Mbps but attainable is 27, snrm is 9.8 dB. The upstream sync speed and attainable increased a lot (up from 12/12 first to 15/15 and then 20/20 and now 20/27) when I removed the unused extension sockets and tidied up the wiring.

Looking at running an ethernet cable using a switch to my devices now, latency of 16-20 is still noticeable as software I use very sensitive, there's a very slight delay which is a pain
