We've had problems with our broadband and subsequently our landline for a long time. We had an Openreach engineer come out about a month or two ago, he couldn't come inside, but he fixed a fault outside with a corroded joint that was slowing our internet/putting noise on the line. The broadband increased speed for a while but then dropped right back down. So I knew there was something else wrong, the broadband speed had dropped back down to 3mpbs download, despite paying for Fibre.
So just this morning I tried changing the ASDL filter to see if that was the problem, and did a quiet line test and it had made no difference. So instead, I touched the master socket and picked it up (it's not attached to the wall) and the phone line started crackling very intensely and continuously just from a slight touch. The internet then turned itself off as well, which almost seems like something is loose.
The internet didn't come back on until I pushed the lead back in, which seems like the connection is loose. The internet has actually went off again as I've been typing this and I've had to resort to using my phone as a hotspot.
My question is; is this something I can change myself along with the wiring it connects to that brings it outside? Or is this something BT/Openreach would deal with? Which obviously isn't possible at the moment with the current situation as they aren't allowed to go inside homes. Also would I be charged for the call out?
Also I've just noticed in this box that is wired to go outside, there's these wires poking out and it generally looks quite frayed.
I'm honestly a bit lost as to whether I can change all this stuff by myself
if you do a bit DIY
then take out screws, remove bottom half and check wires are connected to terminals 2&5
the incoming openreach cable should be connected to terminal A&B on the back plate
make sure all connections are secure before putting front plate back
then check and see if line better and no crackle
