Hi, I’m looking for some help in diagnosing what I believe may be a high resistance fault on my line. I’ve had this issue for the past couple of years but as its intermittent its been hard to get fixed. Calls to plusnet and my previous ISP TalkTalk have resulted in them sending out a phone engineer who has not found an issue on the line.
SymptomsRouter randomly disconnected multiple times during the day. This does not seem to be related to the weather but seems to happen most frequently during the morning. Some days it does not happen at all.
During times when the router is disconnecting I can hear noise on the phone line. Often picking up the phone to get a dial tone can be enough to disconnect the broadband.
Turning off the router reduces the amount of noise I can hear on the line while the filter is connected.
Removing the filter and with just the phone line plugged in I cannot hear any noise.
Oddly removing the filter and then connecting it again seems to fix the issue for a while. I initially thought this might be a filter issue but I’ve tried numerous different filters and have the same issue.
TroubleshootingI now only have the closet socket to my External-NTE box connected.
I have tried replacing the cable from the External-NTE box to this socket.
I have changed the standard phone socket for a NTE-5a socket with components removed so as not to have 2 master sockets.
I have tried mutiple filters, adsl cables, phones, routers
I have connected ferrites to the router power cable / adsl cable and nearby electrical equipment.
I’ve turned off all nearby electrical equipment
I’ve tuned a MW radio to 612KHz and gone round my house and also walked what believe the route to cabinet. ( seems to be an area nearby my cabinet with alot of interference)
Current EquipmentNetgear DGND3700v2 router
Cordless telephone and a wired telephone for testing
High Speed 3m Adsl cable from Tandy
NTE5a master socket with components removed
This is directly opposite the External NTE box outside my house. The cable between them is max 1.5m long. No extension sockets connected.
XTE-2005 adslnation Master faceplate
adslnation XF-1e ADSL filters for testing on the test socket.
I’m around 2km from my exchange. As mentioned I have an external-NTE box outside my house and the phone cable goes underground to my cabinet about 1.2km away then underground again to the exchange.
Here is some recordings of the quite line test.

My stats are being monitored on MDWS. Username big360. I've attached some pictures of my wiring. Any advice appreciated on what might be causing this.
