I live in a small village, 3.6 k form the exchange, copper wire connection, BT hame Hub 4. Until recently the dowload speed on the BT wholesale speed checker used to be around 1.5mb with a max line speed of 2. Now things have got noticably slower - cannot even strean BBC iPlayer without buffering - and rechecking the line speed this is now 1mb max running at 0.64 mb. I seem to have found the problem but what is the expaination?
Not scheduled for fibre ever so may need to look at one of the microwave BB providers as this service is not worth paying for.
Have you tried the quiet line test dial 17070 option 2 you should hear no noise if you can hear noise then it needs reporting to BT faults on 151 with no mention of broadband in the call are you connected to the test socket using a new filter
if using a hub 4 locate these lines located in the hub logs Lines should look like this 19:11:29, 07 Nov. (2290101.460000) DSL noise margin: 7.00 dB upstream, 6.10 dB downstream 19:11:29, 07 Nov. (2290101.390000) DSL line rate: 448 Kbps upstream, 288 Kbps downstream
The stats for the Home Hub 6 can be found on the Information page from http://192.168.1.254 then Advanced Settings -> Technical Log.
