Who has had a BT engineer visit to fix problems?

I got FTTC broadband a few weeks ago and I've been getting slow speeds, often about 5Mbit/s down. The speed estimator said 30Mbit/s. I discussed this in more detail here on the FTTC section.

Here is my SpeedTest.net results' graph:

As you can see, download speed is very mixed and almost never very good, while the upload speed (estimator said 7Mbit/s) is generally very good with a few hiccups. I've talked to my ISP, Goscomb, and they can't find any problems, nor can the wholesale suppliers Enta and BT. The next step is for a BT engineer to visit my home, which will set me back about £120 if they don't find anything wrong.

What are the chances of them finding anything? What success rate (by which I mean a problem was found and the End User wasn't charged) have people had with engineer visits, with any kind of connection? Can any estimate be made for my chances?

You may want to see if they can replace the modem. BT announced a known problem with the VDSL modem at the start of the month that can lead to degradation in performance on the modems, as well as complete failures.

You'll still need an SFI appt for this but as long as it is booked with that request (as BT know about the problem), charges should be very unlikely.

Interesting. Where did you hear about this?

You say performance degraded, my performance was never good.

My VDSL Modem lasted a few days. First sign of a problem was the upload speed dropped from 1.6Mbps to 0.5Mbps. A day later it stopped working completely with the DSL light flashing rather than being steady.

BT/OR came out the next day and replaced it. So far, two months on, still ok.

Your best result was 34Mb down and 8Mb up...

True, it was good once. I meant that it wasn't good and got worse, but that it has fluctuated from day 1.
