Moved into a 1997 built property last year. Paying for BT infinity 2. Intially got speeds in the 50s and 60s Mbps but that has dropped to around 20-25Mbps over the last year (tested on Wifi and wired connections - little diference).
Current setup is NTE5a master socket > Microfilter > BT Homehub 5.
Phone is in another socket in the house with microfilter. Called 17070 to test quiet line. Seemed fine.
Spoke to BT on chat and all they wanted to do was send an engineer for £129.99 but hoped this forum could see if there are any glaring problems on the stats below.
Thanks in advance for your time!
The engineer "charge" is only an advisory to you that you could be charged if the engineer finds a fault with your internal wiring or with your own equipment. If the fault is outside your property or with BT/Openreach equipment there will be no charge.
To rule out your own wiring try connecting the Homehub to the test socket on the master socket and see if things improve
Your data rate is 27.3Mbps and your max data rate is 58.7Mbps. The noise margin is 16.8 which is no where near the optimum of 6. This is indicative of a fault on the line somewhere.
Just to clarify that when you used the test socket, did any telephone extensions that you have become disconnected. If not, they should have and that could be your problem.
If they did go dead and as there is no noise on the silent test and no improvement using the test socket it would appear that the fault is out side your property. You will need to contact BT and report a fault.
You are on an Impacted line with a max down speed of about 67 Meg but you are getting nowhere near that. It's probably not worth being in Infinity 2 for you.
If your speeds are shown as Range B "Impacted" line BT can request that the problem causing it to be within that range to be resolved in order to give the speed as per Range A "Clean" line.
Because of this, BT only quote Range A speeds when you are doing a check to see what speeds you can get prior to purchase therefore showing the Impacted range is a waste of time and of no use in estimating the speeds that you should get..
If your speeds are shown as Range B "Impacted" line
It's not so much the speed you are getting as the Bridge Tap.
Unlike BTr not all ISPs quote just the Clean range.
