Lost 7mbs on Inifintiy 2 overnight

Sometime between midnight & 6am the HH5 reset and reduced my data rate as follows

6. Data Rate: 19999 / 65664
7. Maximum Data Rate: 28601 / 78290
8. Noise Margin: 15.5 / 6.1
9. Line Attenuation: 0.0 / 15.2
10. Signal Attenuation: 0.0 / 0.0

Not sure what has happened but Sam Knows is reporting an increase in Latency of 6ms to 21.7ms. current speeds 59mbs was 66.7mbs

There were no thunderstorms last night (were early saturday morning) & Zens Status pages shows no BT work on my exchange.

most likely the storms took your ES (or disconnects) over the DLM threshold and you have had interleaving applied.

Although DLM is supposed to be intelligent enough to ignore thunderstorms.

Are you on Zen or BT ? (this is not the Zen forum)

I am on Zen, I am 110 meters from the cabinet and in 18 months have not had a single disconnect or resynch.

At 02.16 hrs 05/07/15 the modem lost connection, fast path went to interleaving and my pings went from 8ms to 25ms, also lost 4mbs off the synch.

There were definitely no thunderstorms here that night/morning.

I'm on BT. As you had a similar problem as me then more likely BT playing around then?

Great, but 24hrs later?
This is so annoying

Openreach are currently rolling out G.INP II which could affect you if you are connected to a Huawei cab.

I am on an ECI cabinet and had a clean , almost zero errors line, so G.INP shouldn't affect my connection should it?

Same here. I'm on an ECI cabinet so I don't expect G.INP to have any effect on my speeds / pings unless the ECI cabinet has been upgraded.

My Home Hub 5A's firmware was upgraded to 4.7.5.1.83.8.204.1.11 (Type A) Last updated 05/07/15 and my speed decreased from 50Mbps down to 42. Latency increased from 10ms to 18 after the router rebooted. I'll give it a couple of weeks to see if it recovers.

I don't think the new firmware is anything to do with G.INP as evidenced here - http://forums.thinkbroadband.com/bt/t/4414146-hh5a-n...

I imagine it fixes something else, probably their hopeless attempt to introduce power saving as directed by the EU.

I am
may as well go back to ADSL+ at this rate

Just get a Huawei HG612 v3B and unlock it with the latest firmware, you'll be fine.

got one of those before I moved to BT from Plusnet, will be back in a bit to report any improvement.

TBH it may take longer than a few minutes

In which case I will leave it connect to the DSL on the HH5 - not got enough sockets in the halll & who knows someone might want to call me on the phone!

Stupid thing is the Max data rate is still the same 78047; data rate is 65458 & download 59270

Yeah, but if you can eventually plug it in and use it to front-end the HH5 via it's red WAN socket, you should get good results in a couple of days.

Thanks, will give it a try. Seems a bit of backward way of going forward.

Still no improvement, getting 61 down & 16.1 up
6. Data Rate: 19999 / 65458
7. Maximum Data Rate: 28355 / 78109
8. Noise Margin: 15.2 / 6.0
9. Line Attenuation: 0.0 / 15.1
10. Signal Attenuation: 0.0 / 0.0

So you decided not to use the Openreach modem?

Yes - no change
IP Profile has dropped as well.... IP Profile for your line is - 62.28 Mbps

Time to speak to BT Chat I guess?

Edited by blfamily (Thu 09-Jul-15 07:38:26)

You just have to put the modem in and leave it. It should sort itself out over time. If you runs DSLStats and upload to MyDSLWebStats, it should become apparent what the issues are.

The IP Profile is calculated from the Data Rate.

If you think you have a line fault, you will need an engineer visit to resolve it and he can reset your DLM.

Is your HG612 unlocked? We could do with the xdslcmd info --show output.

Hope these help

on second thoughts, that's taken from the gui not telnet

Edited by deleted (Thu 09-Jul-15 23:04:57)

Indeed.

It's the full info --show we need, as I asked for earlier.

This sounds exactly like what happened to my dads connection. I did put a openreach modem and just left it for about a week. It's now the fastest his line has ever been.

Hope this is fine - copied from Kitz to get the correct telnet instruction

That's the pbParams. I gave you the correct command in my 10:09:06 post yesterday .

There's the direct explanation of the loss of speed. "D: 1259 1". That's downstream interleaving, which typically takes up to 11Mbps off the sync speed. Strangely it also adds to the "Max" figure.

You also have, as normal with interleaving on, "delay: 8 0", which is a straight 8ms addition to downstream latency.

That's about the minimum effect the Openreach DLM has when it imposes interleaving. It takes a few weeks to remove it automatically if the error rates stay low. Very few ISPs would want to get the line reset, as DLM is doing exactly what Openreach intend.

You could ask BT if you wish, but I expect you are looking at around the end of the month for it to self-fix.
