Will my fibre sync speed go back up?


[link to this post]
 
I got upgraded to "fibre large" on talktalk around a month ago and was syncing at around 67500 kbps and upload at 18500. I was happy getting 60Mb on WiFi when the best I ever got on the fibre medium was 25-30Mb,

This is using a Netgear D6400 modem/router also, the talktalk HG633 "super router" synced 10Mb lower and the WiFi wasn't as fast on 5Ghz 802.11 AC either.

But now my line was suddenly unstable new years eve and yesterday. I had to hard reboot to get things to connect again! I even went back to my talktalk router, but the problem persisted. Anyway the connection is okay now it seems but I'm only syncing @ 57103 kbps down and 15652 kbps up even on the netgear. I'm getting 50Mb over Wifi and really don't want it to drop any lower.

Will it go back up again when the line stays stable a while? Or is this as good as it'll get now?

Depends on whether the reason for the instability has gone away. The DLM system can adjust both down and up, and remember you need to restart modems to get them to resync at higher speeds if a period of noise has now gone away

Mine dropped from 75/19 to 35/5. Once the fault was fixed (loose wire in the cab the engineer said) my speeds went back to normal in several speed increases over about a week, i was just using a bog standard BT Home Hub 5.

A loss of 10Mbps or so is normal if the DLM introduces interleaving. If that is what has happened, it depends if the noise has cleared up. Unlike on ADSLx, the FTTC DLM does remove interleaving automatically if it judges the line is now OK. It takes a few weeks frown.

When it does remove interleaving it is usually overnight and it does cause a re-sync.

Are you able to get the full line stats from your kit?

The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.

It was interleaved already, I'm a good 1 mile plus from the exchange and the green cabinet isn't that close either. So as long as it doesn't get any slower I'll be content.
