I'm sorry to say this, but with all the issues people who have BT Infinity seem to be having (including myself) I have come to the conclusion that nobody knows whats going on or what to do to fix it.
I know the adverse weather the UK has seen over the festive period has caused a few issues...but it seems no one has a clue to why everybody seems to be having issues with speeds dropping well below the 16Mbps threashold...I've just done another test and for my 65Mbps rated line and the download rate was 4.5Mbps...other tests dropped well below 2Mbps over the last couple of weeks and even while Technical Support were taling to me on the phone...a test rate of 0.02Mbps download rate was recorded.
Technical support team only seem interested in trying to charge £150 call out fee to send an engineer around to your property to blame your home equipment (just to justify the charge) but seeing the volume of the problem...the fault must lay within the Service/Data Centres, Exchanges and/or the general infrastructre.
Another annoyance is with the main BT Website: the Infinity Speed test tool doesn't work...it doesn't recognise my phone number, therefore cannot match my details to run the test correctly; the 'My BT' part of the website is still showing incorrect call package...despite being notified of this countless number of times over the last 6 months, and the stage 3 TAP test of the BT Wholesale Speed Test still doesn't work due to incorrect DNS settings being supplied by the BT Servers.
All in all a poor performance from BT as a whole...and really unacceptable.
i am in scotland i cant fault it at all my speeds have been perfect sometimes even higher than should be great service
I just posted on another regarding your concerns, i am due to get the service in march and have been waiting gleefully for over 2 years since they announced my exchange was getting done. ( phase 10b)
But now i am thinking of keeping my adsl line with a stable 5 meg connection, well it was when i was with sky, i changed to bt just before xmas and was sent the new home hub 5, been hopeless since i got it,, drops out at least 3-4 times a week and some times you can triple that, Does anyone think it might be a problem with the hubs ? or is it just a poorly delivered and over subscribed service ?
