Broadband connection

Around 100,000 upstream FEC corrections per second and internet dropouts

2: Seeker

Subject line says it all. We have suffered terrible FTTC broadband connectivity (moved from Plusnet to Vodafone because Plusnet did nothing to help).  Our broadband has periods where it drops multiple times a day (especially in bad weather). Openreach visited and said we needed a new phone line to the house, then apparently decided we didn't.

 

Looking at the DSL status page of the router we get:

Time = 0 

Indicator nameDownstreamUpstream
FEC Corrections188461939673641
CRC Error29222


Time = 1 min

Indicator nameDownstreamUpstream
FEC Corrections188461945363617
CRC Error29222

 

That is 5689976 upstream FEC corrections per minute, which is about 100,000 per second. 

 

I know some FEC corrections are a good thing because it shows the correction measures are working, but around 100,000 a second seems ridiculously high. 

 

We are home users and have about 10 things in total connected to the WiFi (computer, laptop, phones, Google home etc).

 

Our questions are:

What is a "normal" FEC correction rate per second for a home user?

If this is high, what can we do about it? 

Is it responsible for the internet dropping out?

 

Thanks

Hey @Bladdvaar!

FEC corrections are a count of errors that have been corrected through the line itself. Whilst yours are showing as higher than I've previously seen, they aren't anything to worry about as it's more an indication that the process is working and doing what it should be.

Your internet speeds can be affected by a number of things and I think in this case we'd need to check your line and router in more depth. 

Could you please also ensure the three steps below are followed:

  1. Please make sure the router is in the most central location possible within the home and isn't behind or inside any furniture that can block the signal from it.
  2. Please ensure there are no baby monitors, radios, microwaves or other routers nearby as this will disrupt your signal.
  3. Ensure the router is away from any reflective surfaces such as mirrors, polished metal or fish tanks as this will bounce the signal back to your router and stop it reaching your devices.
