Disconnects in the night? (Plusnet)
« on: July 23, 2015, 08:06:05 AM »
Hi, getting disconnects in the middle of the night - wondering if anyone had any ideas why? Here is my log.

Router is an 8800NL with dh14 firmware. Thanks.

Isn't this fairly normal for DLM (and/or maintenance) around this time?  Does the below mean the modem sync was reset?

Code: [Select]

Yes may very well be - thanks for the input.

Any ideas on getting tons of errors however? Particularly HEC, talking thousands per second?

Thanks

Hi, getting disconnects in the middle of the night - wondering if anyone had any ideas why? Here is my log.

I don't think it's a disconnect but rather a retrain thats not able to complete the timing is a clue 03:49 that's when the DLM would do it's thing in the wee small hours either to increase or decrease your interleaving depending on your errored second count over 24 hours.

Thanks for the reply,

So is it a problem with my router or line?

It did it again last night and now I am syncing at an even lower speed (dropped from 40mbps to 32mbps in past week)

So is it a problem with my router or line?

It did it again last night and now I am syncing at an even lower speed (dropped from 40mbps to 32mbps in past week)

Just curious why the router log keeps displaying
Jul 25 04:01:12 daemon notice syslog: pppd:Couldn't increase MTU to 1500.
Jul 25 04:01:12 daemon err syslog: pppd:Couldn't increase MRU to 1500

as for the resync's are you getting a lot of errored seconds or very low SNRM ?

I wonder if I have it set up incorrectly? Though I don't see how as I have tried multiple firmwares and I am now on dm2, also I cannot change the mtu higher than 1492 as it won't let me so completely unsure there.

I have had huge errors per sec whereby the internet essentially stops, however since I've been on dm2 it has error'd a lot less, yesterday was almost no errors at all.

If I start using the internet a lot, e.g. downloading a file or streaming the snr does get lower.

At the moment it is a consistent 8.9.

Most of my searching on the web for that mtu error points to the Billion 8800nl probably just some clitch in the firmware though if your PC mtu is set at 1500 then maybe it's trying to set the mtu to 1500 and the modem says no and 1492 on modem and PC at 1492 is great.

Well it's probably just a coincident the new firmware sees less errored seconds because the DLM may have put your line on higher interleaving and this will result in less error's of course this is all hypothetical unless you can get stats from modem and use DSLstats or HG612_modem_stats.

Thanks for the help,

Well I've woken up this morning and the Billion has gone from very low errors yesterday to an awful lot today.

Here are some stats.

B (# of bytes in Mux Data Frame)   23   78
M (# of Mux Data Frames in an RS codeword)   1   1
T (# of Mux Data Frames in an OH sub-frame)   62   13
R (# of redundancy bytes in the RS codeword)   8   16
S (# of data symbols over which the RS code word spans)   0.0236   0.2334
L (# of bits transmitted in each data symbol)   10864   3256
D (interleaver depth)   2753   138
I (interleaver block size in bytes)   32   95
N (RS codeword size)   32   95
Delay (msec)   16   8
INP (DMT symbol)   8.00   2.50
OH Frames   74509644   21017893
OH Frame Errors   5448666   104
RS Words   125256924   1488722
RS Correctable Errors   4109147908   26337
RS Uncorrectable Errors   7694622   0
HEC Errors   1147726   0
OCD Errors   0   0
LCD Errors   0   0
Total Cells   2080649615   0
Data Cells   190925215   0
Bit Errors   0   0
Total ES   21912   50
Total SES   21769   1
Total UAS   54   54

Errors are going up rapidly, particularly HEC.

Line or router fault?
Thanks

Plusnet say there is no issues on the line and likely a hardware issue, so pointing at my 8800nl.

They are going to send me an openreach modem out so I will report back once that is in.

Well the errored seconds (ES) and serious errored seconds (SES) gives us a big clue here there is a big fault and tbh have never experienced a modem causing this amount of errors myself.

And as for plusnet saying there is no issue on your line we need to give them the benefit of doubt and see if a modem swap makes a difference.
