Please help cure sudden drop in BB speed

Go to solution

Following the advice of a BT Openreach engineer I recently installed a new Home Hub 3 modem - the engineer was upgrading my old phone socket to a new 'dual' ADSL/Phone socket and installing new cabling to the telegraph pole outside our property).

Initially I was getting very good BB speeds (for this area) of around 4-5 Mbps however a week ago the speed dropped overnight to about 1.8 Mbps, with many web pages taking significantly longer to load - ironically BT pages seem to take the longest now.

I reset the modem with the hope that the speed may pick up again but 5 days on and the speed is still only around 1.93 Mbps. I ran the BT Speed Test using the following computers (one at a time) connected directly via ethernet cable to either the HH3 GigE socket or the regular Ethernet socket:
MacBook Pro
Samsung Notebook
MacBook Air
Mac Pro
I also ran the same test using WiFi to include iPad and iPhone - same speed results. Nothing else was connected at the time of the tests, not even the phone.

It seems the problem isn't my computers but the modem as the speed coming into it from the exchange is pretty high - 7.26 Mbps.

Any help or advice on how to get my BB speed back to what it was previously would be greatly appreciated.


my speed test results:

ADSL Line Status
Connection Information
Line state: Connected
Connection time: 5 days, 16:22:50
Downstream: 7.094 Mbps
Upstream: 448 Kbps

ADSL Settings

Download speed achieved during the test was - 1.93 Mbps
For your connection, the acceptable range of speeds is 0.4 Mbps-2 Mbps.

And these are the results:

Your DSL Connection Rate :7.26 Mbps(DOWN-STREAM), 0.45 Mbps(UP-STREAM)
IP Profile for your line is - 2 Mbps

Welcome to this forum.


Your IP profile is stuck at 2Mbs.


If you would like to contact one of the UK based BT Care Team who moderate this forum, they should be able to reset it for you.



They can be contacted using this link BT Care Team


They normally respond by phone or e-mail, within three working days, however you should get an immediate confirmation, with a tracking number.
