Lost 10mb/s - need stats

Did have a rock steady 80mb/s - now dropped to 69mb/s
Any chance of posting my connection stats for me.
Thanks.

Sure.
Profile Name 0.128M-80M Downstream, Interleaving Low - 0.128M-20M Upstream, Interleaving On
Downstream Speed 71.9 Mbps
Upstream Speed 20.0 Mbps

Thanks VM MattyC
OK - stable for 100 days apart from 2 resyncs on Mon 4th.
Any Idea what else may have caused loss of speed - does crosstalk reduce speed without resyncs?

Re: Lost 10mb/s - need stats

The (now) standard question of: "Do you have an ECI modem on a Huawei cabinet?" applies.
A 10Mbit drop (and presumably an increase in ping latency, if you're monitoring?) is often blamed on G.INP being enabled when the consumer's modem can't use it.

Re: Lost 10mb/s - need stats

Thanks avatastic
Yes - it is an ECI modem
Yes, ping has increased.
I've no idea if the cabinet is Huawei - it was installed last summer if that makes a difference. How can I find out if G.INP has been enabled?
WTH are openreach doing supplying modems which are incompatible with their cabinets - Sigh.

What is the next step?
EDIT:
I've raised a ticket - but 37 hour response timeHuh Plusnet you are getting worse.

Re: Lost 10mb/s - need stats

G.INP isn't present on your line. It would tell you something different on the test results:
Quote
Profile Name 0.128M-60M Downstream, Retransmission High - 0.128M-20M Upstream, Retransmission Low

The last bit is the teller. It's also a Huawei cabinet that you're routed to.

Re: Lost 10mb/s - need stats

Any other ideas as reason for loss of speed/increase in ping. Sounds suspicious that the symptoms exactly match G.INP on a very short line (around 70m - routed, not direct) to the cabinet.
PS - why is that test result different from the one you posted above?
Thanks.

Re: Lost 10mb/s - need stats

Isn't G.INP not being present simply a symptom of having the ECI modem (which currently doesn't 'do' G.INP so the line falls back to interleaved instead)?

Because I stole it from another thread to provide an example  Grin
@w23 - There's a chance that it could be, but I'm unable to find a way of confirming that. At the moment, Openreach are trialling a way to have the full benefits of G.INP without the side effects some customers have seen. However in this case the test results are showing as interleaving as being on where other examples showed no interleaving at all.

Re: Lost 10mb/s - need stats

OK
If I lose speed due to unavoidable technical issues (such as crosstalk for example) then fair enough.
If on the other hand it is a result of my ISP and/or their suppliers providing me with kit incompatible with the service provided from the cabinet - then I expect it to be fixed.
How about getting a Huwaei modem sent out?

Has the loss of speed seriously affected your use of the internet?

Re: Lost 10mb/s - need stats

Matty's post showing the RADIUS graph looks DLM intervened following something that happened on 3 May - but it whatever happened, it didn't cause a loss of sync that day. The retransmission rollout was completed about 6 weeks ago now for existing Huawei cabs (and excluding new ones from this year).

Re: Lost 10mb/s - need stats

Well after a 5 (FIVE) day wait for an answer to the ticket - (plusnet your support is really going to the dogs)
I got the standard - please carry out all these tests cut and paste - completely ignoring the questions about G.INP

What I am really looking for is some proactive checking - has G.INP been enabled on my cabinet. Surely it must be possible to find this out. There is no point going through the normal fault tests, and an engineer visit just to find out it is a known modem incompatibility.

Alternatively - I am prepared to take the risk on my own - obtain a Huawei modem from Ebay, see if that fixes it. IF plusnet are prepared to part refund me for the cost with a month free, in the event that this is a fix (and hence caused by an incompatibility in supplied equipment)
How about it plusnet?

Re: Lost 10mb/s - need stats

As per the last update we posted in the G.INP thread  (http://community.plus.net/forum/index.php/topic,136287.msg1231823.html#msg1231823) the solution that was trialled is due to be rolled out from tomorrow onwards.
I'd recommend waiting for this to be carried out before you go down the buying another modem router as the trial showed everybody saw things go back to normal.

Re: Lost 10mb/s - need stats

OK - that sounds promising.
Will I need to do anything (eg restart modem) after fix applied?
If so - how will I know when to do it.
Thanks for update.
