welcome to the BT community forum where customers help customers and only BT employees are the forum mods
I moved your post to start your own as the other thread was solved and over a year old
in order for the forum members to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results .
are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem
you need to run btspeedtester with ethernet cable with nobody else on the net and then post stats - don't reset router before test
there is always someone around to help
But the numbers mean that the connection is vastly faster than you said in your first post.
It is very common for the extension wiring in peoples' homes to act as a radio aerial and pick-up radio interference. This interferes with your broadband and slows it down. If you unscrew the faceplate of your Master Socket and take it out you will find another socket underneath called the Test Socket. You should also find that all your telephone extensions have gone dead because they a wired into the faceplate you removed (if not then something is wrong).
If you plug your router into the Test Socket and restart it then you might see an immediate improvement in the router sync rate. For example, I was at a house yesterday where doing this doubled the sync rate, from 3.5Mbps to over 7 Mbps (in this case it turned out that there was a unfiltered telephone on an upstairs extension, but there can be many different causes). You may or may not know how to read your routers stats but it is important to do this because the improvement in router sync rate may not, in all cases, feed through immediately into an improved result in a speed test, although it will eventually. So sometimes people try this and think they have been unsuccessful when really the test has succeeded.
