yes snr is back to 6dB and interleaving has dropped from 1512 to 1306.

Are you implying I should not worry about interleaving depth, error count or disconnects?

Far from it, I was trying to say, It is errors that are probable causing your lack of Faspath (interleaving) etc.…….

Not sure why I had such a spike in errors 60,000.

Do you know if these spikes happen regularly, once a day, week etc? or just a random occurrence ?

Over a Kitz, they have produced a ‘first class’  thread around line stats. errors etc and what they actually mean

The 60,000 errors happened over a random 24 hour period.

Did you have a look at the Kitz link I provided earlier and did this help clarify ?

Yes I did have a look.

 

CRC Errors – Cyclic Redundancy Check

Count of CRC errors. CRC is an error detection code used to verify packet transmission between the sender and receiving end. A CRC error indicates that part of the data packet is corrupt and requires retransmission. – see Cyclic Redundancy Check (CRC) for a more in depth explanation.

Many CRC errors in a short period of time will show a noticeable reduction in throughput speed. This can be an early indication that there is too much noise on the line and in extreme situations can lead to loss of sync (disconnection with the exchange).

now look at REIN vs SHINE and hopefully by then you will be at the same conclusion I think I am at with your connection issues currently.

Take note of @Grisu comments, as I have had BT engineers follow my line back to Cabinet with their AM radio only only to find issues was street light ;-)

Me again.

 

I have contacted BT via live chat about my line errors and interleaving.  They tested my line and said the line is ok.  They believe the issue is with my HH6 (which is not even plugged in).  They are sending me a new HH free of charge (the latest one).  I requested a DLM/line reset and they said they did it whilst i was on live chat, my line speed has not changed, nor has my interleave depth.

 

I have now plugged in the HH6 until i get the new hub, the line speed is the same as the draytek 130, although it is showing a higher max data rate –

current connection Data rate:9.30 Mbps / 32.40 Mbps
Maximum data rate:9291 / 50824

I do not believe they reset my line and DLM.  I will see how it goes with the HH6 and then the new one when it arrives tomorrow.

Is there away of using the HH just as a modem and connecting my Asus 86U for the routing and wifi ?

Hi @Bully

Sorry to hear you are still having issues, alas HH^ cannot be used as Modem, but it can be used to connect to your RT-AC86U if you disable DHCP and wifi, and sett RT router WAN for  Automatic IP, this will still make the HH6 perform NAT and routing which may effect gaming / voip / VPN’s etc?

HH6 will synch slightly better (higher) than the DrayTeK due to it being a Broadcom based Modem .

I will PM you ;-)

I suppose being a broadcom based chip it will not like my ECI street cabinet?

In Theory, It should be OK, just not as Ideal as Matching chipsets with Exchange/cab etc.

I forget, did you have the DSl-AC88U at one stage as that was Broadcom chipset ?

Nope, only the 66U and now the 86U.

Data rate:9.30 Mbps / 32.40 Mbps
Maximum data rate:9329 / 50847
Noise margin:6.1 dB / 9.1 dB
Line attenuation:19.5 dB
Signal attenuation:0 dB / 19.5 dB

Modulation:G_993_2_ANNEX_B
Latency type:Fast Path

Understood, hopefully when new HH6 arrives and settles in you sych will improve, if so then Broadcom DSL is defiantly the way to go for your DSL?

Do you have an old BT modem floating in a cupboard ?
