High FEC Corrections and CRC errors on upstream

sds 3: Seeker

Hello -

 

In less than a week I've clocked up over half a billion FEC corrections ...

I don't suppose there's a firmware fix for this, is there?

Hi!

I was having the same problem as everybody else on this thread, namely:

  1. Low FEC correction count straight after a reboot.
  2. Upstream FEC corrections started growing at the rate of 100K every 2-3 seconds. CRC Errors were still low. No change in anything in the house that could cause electrical noise.
  3. At some point, the CRC Errors started to grow into the thousands, after which the connection got reset and the cycle would start again. The whole cycle would last about a day.

A week ago, I got rid of the Vodafone router, bought a proper one and now connection is stable and has not dropped once since.

The irritating thing is that we KNOW it's a firmware issue. However, in order to have it fixed, Vodafone should:

  a) understand what the problem is;

  b) acknowledge the issue exists;

  c) ask Huawei, who manufactures their router, to fix it.

 

After hundreds of posts in this thread, there is still no evidence that either a) or b) has actually happened, so forget about a fix for the time being.

Sad, isn't it?

Thanks for getting in touch @sds, we're really sorry to hear about the FEC errors you're getting; one of our Broadband Specialists will be happy to check if there's any firmware updates available. So they can do this, I've sent you a private message with details on how to get in touch.

@ccristal We're glad to hear that your new router is working great and we'll make sure to pass along your feedback regarding our own. If you have any further questions in the future, don't hesitate to get in touch and we'll be happy to help in any way we can.

TJ - I also have the same issue with cycles of increasing FEC upstream numbers, often getting into the millions during the evening.  I spoke to Tech2 but they weren't aware of the issue and said

- it must be a fault with vf broadband app

- they couldn't see any errors on the line

- I could ignore the FEC upsream data

- they said they would make higher management aware and let me know , but not heard anything yet.

There does however seem to be a trend that when the FEC upstream numbers get very high there is a "WAN disconnect".

Hi Bill - had this problem for the first few months of VF broadband, strange but it all settled down with little intervention other than each time it started to clock loads of errors I reset the link - I no longer have to reset my link with my current session uptime approx 25 days and a total of 200000 errors. I seriously believe that the router is oversensitive to line noise with a number of people having changed their router to get better stability. If you have a spare router then VF will give you the login & password so that may be a way forward, best of luck in getting it sorted.

The FEC error counts should be figures retrieved from the OpenReach cabinet, and these should not reset if your reboot or power-cycle the router!

 

So with the VF HHG2500 in circuit I get around 1,000,000,000 FEC errors reported DAILY!  Using my DrayTek Vigor 130, I've had just over 5,000 since MAY!

Hey @sds I've had a look at the post and can see all the feedback from the community on this issue. I'll forward these details on to one of the back office team who deals with our router. Can't give a timescale on an answer just now, but as soon as I hear anything I'll post an update.

Haha. Funniest post I've seen in a long time. The issue has been astounds for 18 months at least with no fix to the firmware.  No matter which team picks this up it never gets fixed.

Bumping this thread as I still have serious FEC errors....

I was one of the first in Themis thread 18mo ago, I still get the update email for new people who think theirs is a fix that has been fixed. I completely agree with the two previous posts. This is a shambles. 

 

Ive been using a modified bthomehub5 running LEDE for 11months and my FEC rate is about 30 a day. The disconnects don’t happenen anywhere near as often and my speed has crawled back up. Currently online over 4 days with 135 FECS.

The moderator will send a private message to users of this thread that will be an email address to tech support who will not get back to you. It’s even the same moderators that we’re doing this over a year ago sending these messages. You’d think that they would take some  initiative  in their job and actually press their managers with this exact fault, with this large customer dissatisfaction and this clear waste of their time. I’m still with Vodafone because the price and service (outside this router nonsense) is actually good... but I’m missing part of the deal they promised me. No matter how many “sorry to hear you’re having a problem” responses that the moderators give, Vodafone are just failing here and if somebody who felt passionate about it enough would get in touch with them at a corporate level, or contact bbc watchdog, something might just happen. I personallly have given up and changed my router.

I think it all comes down to: Do VF think there is any reason to fix the modem/router?

 

The supplied router has multiple functions that are "not supported", and various functions that have been deliberately hobbled, by the looks of it to try and improve that stability of the router.  Now there is nothing inherently wrong with the chipsets used in the router, you can find them working flawlessly in other devices.  Everyone of those other devices though will have more ventilation in the casing and decent heat sinks on the main chips.

 

The average HHG2500 modem that VF supplies is going to be fine for web browsing and internet streaming, but as the heart of a more complex home network it's simply not upto the job.

 

I'm kind of guessing that VF see little point in fixing a firmware reporting bug, on a modem that is already almost completely unfit for purpose!

@KeithAlger Hi there, just a quick update on this issue. Our Third line team are currently running tests on the router assisted by a Line engineer to investigate this and how the firmware reacts to FECs caused by internal or external factors.  As soon as I have any further update or resolution on this I'll be in touch.

Any update Joe?

I don't know if it's relevant at all, but it seems odd that using the Draytek Vigor 130 which doesn't seem to generate ANY FEC Corrections G.INP / G.998.4 is active but only on the uplink!

@Siygess Hi there, I'm still awaiting an update on this from our 3rd Line team. I've sent a chaser email off to them looking for an update and as soon as they get back to me I'll be in touch. Thanks for your patience on this. Joe

@Siygess I've had an update from our 3rd line team, they've tried to replicate the fault using the router and getting 3rd party engineers to introduce noise onto the line to try to replicate the fault. They can't seem to get this to match the FEC errors you're all seeing. I'm just wondering if you'd be able to send me the GUI logs and counter details so I can send these off to get this looked into further. Please let me know if this is OK and I'll send you a message on how to get the information to me. Joe

Sure, send me what you need and I will collect the data in the morning.

I'm disappointed that, after 18 months and dozens of posts, we have now returned to the situation where 3rd line want to see gui screenshots to somehow prove that this isn't in all of our collective heads.

 

There are already screen shots showing millions of FEC errors - can 3rd line not simply be referred to this thread and review the details already provided?

I can send the information if you want as mines crazy.

@Siygess Thanks for agreeing to do this. I've sent you a private message with the details I need and where to find them on the GUI. If you can ask in the email to send me the attachment so I can get them off to 3rd line. Once again thanks in advance. Joe
