After two nights of ridiculously high error rates recorded in DSLStats my connection speed has dropped from 48Mbps to 40Mbps and INP has increased from 3 to 8:
Average error rates for 13 Jun 2016
CRC erors per hour: 45389 Down, 0.30 Up
FEC erors per hour: 74501500 Down, 0 Up
HEC erors per hour: 21695 Down, 0 Up
ES per hour: 738 Down, 0.30 Up
SES per hour: 0 Down, 0 Up
Average error rates for 14 Jun 2016
CRC erors per hour: 14769 Down, 0.19 Up
FEC erors per hour: 24465064 Down, 75.5 Up
HEC erors per hour: 6770 Down, 0 Up
ES per hour: 236 Down, 40.1 Up
SES per hour: 5.70 Down, 0 Up
I've only had this unit running for a few days and after initially giving very good results something seems very wrong as I wasn't seeing this on my SBG3300-N.
Does anyone have any experience of this behaviour and do I perhaps need to change any settings in the router. Currently running the latest firmware 1.00(AAKL.14)C0.
Any help would be much appreciated.
-
I am trying one of these with same Firmware version as your good self. while having around a 1MB drop on both US and DS I have a resync around lunch time and have had 12901 FEC, 839CRC and 113 ES. I did read on hear that some people thought there was an issue with this version of Firmware
-
Not that it helps but my 8324 is on 1.00 aakl.14 c0_20160408 currently gets around 400-600es ds per 24 hours since being on fastpath after the loss of g.inp.
-
Main issue for me is I've actually lost 8Mbps and my interleaving level had trebled. today I seem to be getting constant connection drops too see attached.
If it is a firmware issue rather than a setting issue any idea what is the most stable version at present?
Strange that it's happening on this and not on my SBG3300-N which I believe has the same chipset.
-
wow, doesn't look good, was the modem new out of interest or 2nd hand - wondering if its faulty ?? not sure if it makes any difference but I only use mine in bridge mode rather than all in one,
here's mine on 31 days uptime on the lastest version. Sky 65/20
are you uploading to mydslwebstats?
-
Bought it off a well know auction site but tbh it looks pretty much brand new, was fully boxed and still had cellophane on it.
This could actually be a line issue timed to perfection with me swapping the router mind. No real errors at all this evening but as said I've lost 8Mbps, interleaving is 3xs worse and my ping has increased to levels I've never seen in my 4 years on FTTC. It wouldn't surprise me as for the last few days my PlusNet profile has been getting stuck too, on two consecutive days I've had to call them to get it manually changed.

It may have been my post your referring too? my router is the VMG8324-B10A.
If I use version 14 firmware my FEC is up over a million but only after it's been turned on for more than 1 hour.
I dropped mine back to version 7 and it's fine now. so for me at least version 14 is a no go
-
Cheers yeah that was the one. New I had read a post about it. Will leave mine and see how it runs overnight and tomorrow then decided what I will do. Must admit that the billion880AXL just used to run on my line
-
@daveesh1
How are the errors looking today?
Mine ran fine for the first 24 hours and actually increased my connection rate on the downstream while dropping around 0.5Mbps on the upstream before this happened.
I'm still seeing approx 6.5 million FEC's per minute reported in DSLStats but hardly any CRC's etc. again at present.
-
Well after my speed dropped yet again by a further 1Mbps, so far dropping from 48Mbps to now 39Mbps I've rolled back the firmware to 1.00(AAKL.7)C0.
So far I'm seeing very low error levels but tonight will tell. on 1.00(AAKL.14)C0 I was seeing huge amounts of CRC's, HEC's, ES, SES and FEC's where at over 800,000 per minute!
My interleaving has also risen again now up from the original level of 850 to 2500 to now over 2800 :o
Fingers crossed it stays like this and DLM sorts my line out as said my connection speed is now around 39Mbps and the Max Attainable is 55Mbps!
-
@Busa Its hard for me to tell as all I keep getting out of DSL stats log is unable to login to Modem/router this is even after I power cycled the modem this morning there is no other telnet session open to the router so why it is doing this god only knows but there is info in Mydslstats. So if we go off the info I have around 50ES per hour 600FEC per Min and 30CRC per min. All I can say I so far I am not impressed with this router and are really considering going back to my Billion...
-
Strange DSLStats is working fine here.
-
This 2nd hand Billion 8800nl is working like a dream with increase of sync and attainable and the most important part as stable as a HG612.
I did read a post by Chysalis that the VMG8924-B10A seemed to increased the errored second rate by 300% or 3X more than a HG612 and the Billion 8800nl only increased the ES error rate by 30% or 0.3X
A question to Busa how many errored seconds did you see with the SBG3300-N in 24 hours and how many with the VMG8924-B10A
-
I used to average 2 to 4 E/S per hour with the SBG3300-N, take a look at my original post above for the E/S on the VMG8924-B10A.
Since switching to the 1.00(AAKL.7)C0 all is looking good again on the error front, well apart from interleaving at 2800 when it was around 850 and my download speed some 9Mbps less now.
I really shouldn't tempt fate though! :no:
-
Well if we take 738 errored seconds in one hour 738 X 24 hours = 17712 that is well above the DLM threshold for a speed profile of 2880 ES over 24 hours and the reason the DLM took action on your line with the VMG8924-B10A with up to date firmware.
The SBG3300-N would show 93 errored seconds in 24 hours to me I can't understand how a new firmware with the 8924-B10a could cause so much extra errored seconds :-\
edit 738 X 23 hours = 16974
-
Crazy but so far on the 1.00(AAKL.7)C0 firmware all looks good this morning:
Average error rates for 17 Jun 2016
CRC erors per hour: 0 Down, 0 Up
FEC erors per hour: 91654 Down, 0.78 Up
HEC erors per hour: 0 Down, 0 Up
ES per hour: 0 Down, 0 Up
SES per hour: 0 Down, 0 Up
There I go tempting fate again! :-X
Speed has come up 1Mbps and interleaving now coming down again, currently at 2517.
I'll leave it as is and see if DLM does it's stuff to bring my speed back.
-
Well 3 re-syncs in 6 hours not good..
-
Well 3 re-syncs in 6 hours not good..
Have to say if the DLM line history has been good and then a issue has occurred over a few days the DLM can start to recover the line quickly with 2 to 3 DLM retrains per day and during this process don't even think of turning off the modem.
-
@daveesh1
Which version of the firmware are you on and what cabinet type?
-
He is on eci. He had a resync this morning but in his favour as sync rate went up along with snrm rise on the ds. I would be tempted to leave it alone for now. He is on fast path same as a lot of us who lost g.inp on eci
I dont like the look of his tbb latency chart though. I wonder if this is what a congested link looks like??
Mine is the second (8324)
-
Now I have a Samknows box and that was the time it did some samples.
-
Hmm still looks pretty messy to me as I just looked. I would be turning it off to check thats what's causing it if it were me...
-
Well I've given up on the VMG8924 B10A today and gone back to my SBG3300-N as it has totally destroyed my connection.
I've tried just about every firmware available and unless the unit is faulty I'm not sure what is going on with it.
Anyone else had any issues such as constant disconnections, the GUI suddenly not being available, DSLStats failing to login to modem, constant ping spikes on my TBQM, interleaving increasing from 850 to over 2800, ping increasing from around 20ms to 40ms? The list goes on.
Shame as the unit itself seems pretty good with plenty of options, more than on my SBG3300-N and I like the GUI. :(
-
Me thinks perhaps its faulty due to the other issues you have had. As I said I did have the time gap issues on the 8924 but no other issues with gui or latency issues etc.
Personally I think having 2 devices is a better option than all in one. Is it still under warranty? - my 8324 has been up for 38 days on v14 although I do run it in bridge mode.
-
Just wondering if it's worth using my SBG3300-N as the modem and just using the VMG8924 as the router for now? Is it easy enough to setup?
If that can and will work I may just run it like that until G.INP gets switched back on in my ECI cabinet.
I have OR coming again tomorrow as my line speeds have dropped below the FTTC A range, who knows I may actually have a line fault and it wasn't the VMG8924 after all! :-\
-
I would see what or say first before making any further changes. I am on eci cab as well. Dont hold your breathe getting g.inp back - seems to be going on and on. Just over 2 months now since mine was disabled (was on an 8800nl but stopped using it due to high errors). Re eci cab on my line the best result has been with zyxel after trying several options.You could use the 8924 as a modem and use a router behind it but I dont think you can do it the other way. I would see what OR has to say after the visit and maybe if they say no fault etc and your 8924 is in warranty then perhaps get it changed. Personally I couldn't get on with it due to the missing minutes hence using the 8324 in bridge mode along with my ac87u
Keep us posted.
-
My experience of OR has not been good tbh, I seem to have all the lazy or useless staff in my area and have actually had them make my line far worse in the past.
None of the visits I've had over the years (and it's been a fair few) have convinced me they know what they are doing, I even had one who didn't have working test equipment and he swapped the pair I was on without testing it, again making my connection worse and he left without even letting my modem connect first to see the result! I was fuming that day.
I can only live in hope that there is at least employee of OR who is good at their job and conscientious with it!
-
Well after yesterdays OR visit my line rates are lower than ever and the VMG is still totally unstable with the GUI failing, can't login to DSLStats randomly and a very busy TBQM so I've put my SBG3300-N back on the line and all seems ok again now.
I may try using my SBG in Bridge Mode and connect it to the VMG just as a Router (if possible?) so I can use the 5Ghz wifi to see what happens, I'll keep you posted.
-
Just noticed I've also lost D3 from the Downstream SNRM Graph in DSLStats, anyone advise what that means?
-
Well I've setup my SBG3300-N in Bridge Mode and now using the VMG8924-B10A as a router. Seems to be working with the best of both units now but no DSLStats, is there anyway to configure this setup so I can use DSLStats?
-
Today I decided to try the VMG 8924 B10A again on it's own on firmware v14. I switched off bit swapping and although my FEC's are very high the SNR seems stable and errors whilst a little higher are still at reasonable levels.
Seems the 8924 marks bits as unusable and slowly lowers the SNR over time if bit swapping is on.
-
I had the same issue.
DSL driver after v7 was changed and all fw had the same issue after v7.
They have released v15 now, with a new dsl driver - maybe worth a try.
-
A little too late for me I've just jumped ship from the disaster that is PlusNet to join Virgin Media, I have any amount of VDSL modem/routers I no longer need so may put them on a well know auction site :P
