I believe I have a 'hr dis' fault again, I can hear crackling/pops on the line when the VDSL2 signal is active (router/modem connected). SNRM drops, CRC/FEC errors go through the roof, sometimes enough to lose sync.
When there is no modem/router connected and a corded phone connected to the test socket, there isn't really any noise, perhaps a few pops/crackles.
Is it worth getting BT to try to fix this again?
4 months ago it took 5 engineer visits before they did a line pair swap and I'm sick and tired of going through support again...
