Broadband & Home Phone

60,000 fec corrections every 3 seconds and really slow speeds

7: Helper

I was with SSE broadband on standard fibre no problems or issues hardly no fec errors or any other errors ,  i got the stable sync speed of 33.6 mb for the length of the contract. , i saw an offer on vodafone and the vodafone website says i can get vodafone max . As you all know standard is 1- 37mb and max is 38mb to 79.9mb , The website says my line is 32 to 44 mb , so because i can have max then i would have thought my new speed would be somewhere from 38 to 44mb ,

My live date came and i went from 33.6 with standard sse to 22 meg with vodafone max . Over the last 5 weeks the best sync was 27.9mb and the worse sync speed is 16mb , I had 4 bt openreach engineers here thats has run checks and says there is nothing wrong at all with the line etc , They say it's a vodafone build profile issue that's causing me all the errors and making the LINE D L M kick in and change the sync all over the place , The only things bt has done is change the port in the fibre cab to a difference one change the master socket and cut back my wires here , on the pole and the fibra box and reset the D L M a couple of time but the last D L M did not seem to reset proper and gave me the speed of 24mb , tried to reset it again and the best it would go was 27.9 .

The other thing is when they reset my line and i plug the router back in i don't get any errors for about 4 hours , this has been the same for the last 3 reset when the router was plugged back in , after about 4 hours i start getting somewhere from 30,000 to 60,000 fec corrections every 3 seconds on upload  and about 3 to 7 fec on download , and about 350 crc errors on upload in 2 days 11 hours ,

If you have access to one it is worth trying a 3rd party modem router (not vodafone).  I had the same issue got 2 routers off Vodafone both with the same issue.  Switched to an Asus modem router and don't get the errors.  Upload speed instanly increased from 4mb to 6.5mb.

It seems to be something unique and deep seated in the Vodafone router firmware, sadly. The only real solution is to ask for your username and password and move to a 3rd party router. I had the same problem early on and DLM slaughtered my line. 3rd party router and 18 months later, very low errors and DLM has slowly relinquished its stranglehold.

There is a very long running thread about it here:

Changed my router for a technicolor tg589vac which does seem to make the internet more responsive  60,000 fec corrections has gone from 60,000 every 3 seconds to 15,000 per day so far ,download fec corrections seam to be about the same 4000 a day , crc download may have gone up by 300 per day , open reach reset my line D L M so the tg589vac starts a fresh to see if it stops the sync issues . will update after i know more
