If that's what it is then he showed me that the maximum throughput is 79000 kbps. The max speed he will have shown is the speed that can be got before allowing for error correction overheads. Unless you are fairly lucky, there will be need for a significant error correction overhead. I typically have a max speed of 82Mb but a sync 72Mb, so profile around 70Mb and download speeds around 68-70Mb. Such results are typical for many others as well; and of course, there are many, many others who would love to have such results.
It looks as if early on you were lucky and had an almost error-free line. Now more people have joined Infinity there is more crosstalk and hence more errors and more need for error correction. It is just a fact of life that everyone's speeds on Infinity are likely to go down as time progresses. Your estimate even allowed for that. They may go up again if BT introduce a new technology such as vectoring or FTTP.
You don't want me to complain about a 11mb loss in my download speed and sit back? Yes, sit back and enjoy the excellent connection you have. Perfectly reasonable to enquire as to possible reasons and to try to have it improved; but not to assume that you have a right so such speeds because you were once lucky enough to have them.
Yeah, I think its time for me to leave BT. I can't express how happy I am for not renewing my contract.
The engineer showed me the syncing speed of 75,000kbps(apx). Having proven several times that the line is capable of 73-75 mb, doesn't seem to bother anyone.
My request at all times was to get the profile raised by BT wholesale, it has come to my attention that not only as a customer you will never be able to get in touch with them but also not a single employee of BT even wants to get in touch with BT wholesale.
BT are ultimately a very cheap company and are only after your money. Building an infrastructure of BROADBAND on something that is clearly not able to handle that many connections. I asked the engineer why do majority of BT's customer never get more than half the speed they are promised, he told me that the pole outside was only ever made to handle 4 broadband lines, now it has 20 or more. If this isn't alarming, I don't know what is.
Their service is simply unacceptable, I have read so many cases on this forum where customers are being charged upto 130 Pounds for work being done outside of their house.
As to this part of your post "he told me that the pole outside was only ever made to handle 4 broadband lines, now it has 20 or more. If this isn't alarming, I don't know what is"
That is just total rubbish
I think I am going to believe an Openreach engineer than an admin/ mod from this forum telling me its total rubbish.
i am a customer like your self just like all the other forum members apart from the Mods/admins who are BT employees
