High FEC Corrections and CRC errors on upstream

willink

2: Seeker

Can anyone advise if FEC upstream corrections increasing 3000 every 3 seconds is normal...  Just about to clock 100 million in 2 days.

 

I'have had dropouts of IM clients (not broadband connection though) since my line moved from BT to Vodafone.. BT on Fibre has been stable for years before the move.

 

Even disabling wireless on the router, connecting only 1 laptop to the physical port and having no internet activity there is still a 200 per 3 second increase...

 

This says to me something is wrong somewhere... CRC error count is 8775 after 2 days as well, downstream looks good 6 corrections and no CRC errors...

 

I woudl prefer to use my HG612 and synology router rather than this connect piece of crap. or at least for a test to rule out hardware fault. Was told it would go in modem mode by vodafone store when I agreed to move over and that's not available either.

Spoke to VF support, as much use as a chocolate teapot... so hoping someone in the community has seen these high errors before, or maybe someoen from vodafone but I won't hold my breath...

Thanks for the update @Ejsime. I'm glad to hear everything was sorted when the engineer visited you 😊

Think it's time for me to comment further on this post as my FEC corrections have recently settled to a very low level -

I'm still using the VF router supplied & same firmware it's been using for 4 months (detailed elsewhere in this post) -  When I was clocking large numbers of errors I found that if I reset the link the counter would then only increase slowly perhaps 40 a second and this would continue for several days, then the errors would start clocking much faster until the counter was clocking as many as 100,000 a second. Persevering I have reset the link on numerous occasions until recently I noticed that the number of errors per second has drastically decreased now averaging 1 every 10 seconds (for about 2 weeks now).

So what's changed - I have done nothing at my end, no equipment, cabling or configuration changes so where I originally asked whether this might be a VF router issue I believe I can catagorically say that it was something external to my house, which was causing the errors, that has now been fixed.

I will update further if the current situation changes.

I have been having issues with my connection for months now. I initially noticed my speed was capped below the minimum guarantee and called Vodafone to check what was up. My connection was not nearly as bad as it has been getting recently.  I'm seeing dropouts multiple times a day, sometime multiple times in an hour.

 

I've had 2 BT engineers to my house (one of them saying 4 engineers have been assigned to the case), a brand new router and removed all my powerline adapters. Each time the engineer has reset the line giving me well above 60Mb/s speeds, but this quickly decreases to 30-40Mb/s as the error count increases into the millions. Nothing has helped so far.

 

The worst part is that I was hopeful about Vodafone's support but we're now back to square 1 and I'm being asked to plug my router into the test socket again.

Hi @sfowler9 I do appreciate why this would be frustrating for you. As you're still having problems, it must mean there is still something wrong. So we can chase this up for you, please send us your details by following the steps on the private message I've sent you. 

 

 

Same problem here. Six years with no issues on Sky and switched to Vodafone on Monday, and have regretted it ever since.

Constant dropouts / disconnections, speed wandering around 6Mb/sec (it was 30 with Sky) and I have hundreds of millions of these FEC corrections:

I thought I would reply to this.

 

I am now very happily back with BT for 4 months having spent 28 days with Vodafone. I too experienced the same issues, dropouts, Millions of FEC errors, slowness and instability with Vodafone, but decided to cancel the service within the 30 days. 

Since moving back to BT, the line has been incredibly fast and stable...back to where it was before making the mistake moving from BT to Vodafone.

I would recommend to move away from Vodafone and if you have just moved over and experiencing issues, I would move back (or to another supplier) and cancel the service ASAP with Vodafone.

@scott_lk I'm sorry to see you're having problems with your broadband. Our specialist will be happy to discuss this further with you as I know it's important to get the service you're paying for. Please send us your details via the private message I've sent you. 

Thanks - form completed

I just tried to reply to you on PM, Adam, but got the bizarre message that "You have reached the limit for number of private messages that you can send for now. Please try again later."

 

Anyways - after three weeks, this still isn't sorted and every time I talk to the contact centre they basically treat it as a new incident. This is beyond infuriating.

Is there any chance that one of your team could escalate the ticket for me?

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?
