FEC Errors and internet speed

What is a normal amount of FEC erors for my modem?

This picture was taken at 5h 15min 42s of link uptime inside modem and it showed 61421 FEC errors https://ibb.co/P65qRJY (as you can see in this picture)

After 1 minute i log in again to check do i have more FEC errors and my modem actually shows less errors then before https://ibb.co/g70SMqz (as you can see in picture) and i did not reset modem or lose connection?

How can my errors go up and down its seems soo random. One time it will show 10k in a minute 2k and back to 5k and maybe in 5 minutes it will be 0?
Is this normal?

And one more thing, can i get any faster internet though my line? The maximum it shows 55/15 so can i get maybe 30/6 ?

my thoughts

FTTN VDSL Speed Tiers are …. Profiles are….

100/20 … 110/22

75/20 … 90/22

50/10 … 60/12

25/5 … 32/6

max sync needs to be greater than profile

If you max sync is 55 then profile would be 32 speed tier is 25

FEC should be Average 100 or less per minute, 1500 in 15 minutes, 6000 per hour, 144k per day.

Note that storms will cause higher FEC counts, thus consider only dry days.

What gateway do you have I don't recognize the web interface?

I've noticed an odd thing lately where my errors will reset to all Zeros after a short internet outage, even though the gateway will keep running it's uptime counter.  

For example(with random made up number):  Gateway has been running 7 days has 50,000 FEC errors (plus other errors).  Internet goes out for 30 seconds.  if you check gateway immediately after it returns it'll be at Zero FEC errors (and all other errors).  Will still say it has been up for 7+days.  Obviously if you don't check it immediately errors will build back up again.  I've found this obviously makes average errors divided by uptime a unreliable metric.  Since it artificially makes it look like there are way less errors than there really are over that time period.  

I've mentioned this to the advanced tech support and they didn't have answer.  I also had my bgw210-700 replaced and it happened with old and new one so it's not a problem with the gateway itself, although it might be a bug in the firmware.

We understand that you have questions related to FEC errors @madmax988. We're here to help.

 

Our Ace is correct, FECs will not be a problem until you're getting numbers up to 10-100 million/15min block.  Thousands is not a problem as they are corrected. 

 

Please let us know if that helps answer your question.

@ATTHelp if you are getting 10 million fec errors every 15 minutes I can't imagine you wouldn't have crc errors and errored seconds as well thats a massive number and very different than the 1500 fec errors @mythoughts stated.

Also my issue right now isn't the number of errors it's the fact that the gateway isn't reseting/counting them correctly.
