Thank you. That is very helpful.
I had previously fitted an ADSL V1.0 filtered faceplate at a different property. At that time, I also had to move the extension wiring to the new faceplate. The appearance is very similar to the Solwise version and it has always worked well.
I was previously unaware of the Mk3 faceplate. It seems to go between the existing faceplate and the NTE5/5A master socket, which avoids the need to change any of the wiring. All of the existing voice extensions become filtered and I gather that I could also plug a modem lead directly into the front of Mk3 faceplate, without the need for a separate splitter/filter. Installation of a permanently wired data extension could follow subsequently. Is that correct?
You recommended an Openreach Mk3 filtered plate, although you did say they are hard to come by at a reasonable price. I found this product on-line at www.run-it-direct.co.uk/adsl-vdsl-faceplates/btvdslfaceplate/. Is it the correct one?
Please see the photo of my existing master socket at www.dropbox.com/s/ob232t8lwh2ityu/Master%20socket.jpg?dl=0. Openreach installed that socket at least four years ago (probably more) and I know the engineer disconnected the bell wires. As an added precaution, I disconnected the bell wires within the extension sockets. Would the Mk3 faceplate be compatible with my existing master socket?
As you say, the Mk3 faceplate is not cheap. However, it would still be a worthwhile purchase, if it avoids the need for an expensive visit by a BT Openreach engineer.
Incidentally, I have just noticed that dropouts seem to commence at around the same time every day. On most mornings, the Internet connection remains stable until around 11:00 am. Dropouts commence before midday, and the system remains virtually unusable throughout the afternoon. It stabilises around sunset and the router resets at 00:30 am every night. I don’t know whether that is because DLM triggers a reset. The timing is rather strange and I wonder whether the dropouts could be the result of external temperatures or other factors within the BT network. However, sync speed has reduced even further today and has fallen by almost 20 Mbps during the last three weeks.
