Wall of text incomming, and I should preface it by saying that we recently (10th Jan) got upgraded to FTTC, but there were problems with the old line before then, in that it couldn't hold sync speeds very well. The prevailing theory was that this maybe an issue with water getting into the street cabinet or something, as the issues tended to occur when the weather was bad. With the move to the new cabinet for the FTTC, it was hoped that this problem would be resolved., however it doesn't appear to have been (or possibly it was resolved and now an entirely new problem has cropped up! /positive thinking).
When the BT guy came around to install it, he did mention that there were large amounts of errors on the line when he was running his tests, but the line worked well enough when it was all plugged in, so his suggestion was just to leave it and then see what happens, and if problems occured then to contact their support (Which is the next stage now if no other options present themselves).
For the first 7 days the line was working flawlessly, a solid 27Mbps-ish. However, starting on the 17th we began to notice packet loss start to appear (there were trace amounts of packetloss before the 17th, but not this bad.
See: 12th January
Running speed tests has also turned up weird results. In the days following the install the thinkbroadband speed test was fine, but it has deteriorated massively:
However using the bt speedtester, it shows the line as being perfectly fine, 27Mbps. and the results from other testers such as speedtester.net fluctuate wildly, but often display 14-27Mbps while thinkbroadband is showing 4mbps.
I also just tried downloading a game off Steam and was getting 1.3MB/s. Which is slower than the 2.7MB/s we could theoretically be getting, (and in fact, slower than the 14Mbps we're supposedly guaranteed) , but still much faster than the 4.4Mbps that the speedtest i ran before hand just quoted me.
ISP: Zen Internet
Modem: BT Openreach/Echoreach HG612
Router: Buffalo Airstation WZR-HP-G300NH
Operating System: Windows 7
The BT number checker thing says up to 27.5 up, 11 down, though when the guy came round to install it his tests indicated up to 36 up and 2 down.
I'm not sure how to get at the line data for my modem, as it goes through the router, so any help there would be appreciated.
