I've been trying to find what's wrong with our broadband, Looking at the Old BT faceplate I wondered if it was suitable being that it's probably around 20 years old.
It's BT property but as we haven't paid them directly for a few years I guess they don't care if we are getting the best signal.
The wall plate is a NTE5 (network termination equipment) the version fitted has three screw terminals inside.
after a bit of googling I find out this type has some sort of device in-line that's not great for high speed internet.
I spoke to someone who recommended this
https://www.run-it-direct.co.uk/adsl-vdsl-faceplates/btvdslfaceplate/
it cost about thirty quid and is now connected to the two wires white and orange that come out of the wall.
easy job only need a flat blade screwdriver and pair of snips ( or nail scissors)
I chucked away the old thing.
it hasn't cured all the problems we had but has made a huge difference.
