FTTC speed halved in the last week...

Well after signing up for BT's highest speed option for FTTC here, I was getting reasonable results until this week:

The download speed has halved and is almost the same as I used to get with ADSL... whereas the upload speed has declined just a bit.

Has anyone else seen this?

Removed your public IP address before someone makes you lose even more speed due to traffic pointing at you

Thanks. That was a bit silly of me...

I rebooted the HH5 and the speed has considerably increased (and the IP changed), although still not quite the same as before.

Nope, pretty flat. I guess that could be making a difference, also I noticed an OpenReach guy working on the cab that serves me last week. Will more FTTC users slow down the line noticeably?

Sounds like you got a low sync speed from a burst of noise and the usual restart resolves it.

Modems do not reconnect automatically when things improve, as this would mean broadband would be on/off an awful lot more.

Am still getting speeds about 10% lower on both upload and download since signing up with BT Infinity 2.

Mon 20/07/15 15:14 54.05 Mbps 54.47 Mbps 8.29 Mbps

Wed 19/08/15 12:55 49.03 Mbps 49.08 Mbps 7.32 Mbps

The degradation happened about a week after the initial install, and has remained pretty constant since. Rebooting the HH5 has little or no effect.
