I'll try to keen this as short as possible...
Ongoing broadband problems for several months. Dropouts and slowdowns. Report to ISP (Talktalk - not through choice, they acquired previous ISP) They got BT out.
Engineer replaced wiring from pole to house and installed new Master socket. All other internal BT wiring disconnected. Problem hasn't gone away and there is no pattern to slowdowns/drops etc. Speedtest.net results from August on this page. That's when I've been able to run tests. Frequent timeouts and loss of connection over and above performance.
When a wired or wireless phone is connected to the master socket there is zero line noise. There is zero line noise whether or not a filter is connected, but as soon as a router is connected the line noise is terrible.
Things have now got untenable. Talktalk say line noise problem so I have to take it up with BT (although they were happy to deal with it in August).
Tried two different routers, including a brand new Netgear bought especially to try and resolve the issue which wasn't cheap Four different filters, two router -> socket cables, but still hellish line noise no matter what the combination yet as soon as router is disconnected the line is clear as a bell. There are no connected extensions or anything else plugged into Master socket.
I really don't want to have BT come out and say "It's yer kit guv" and charge me for the visit, but I can't see I've got any choice. Any suggestions before I go down that route?
Thanks in advance.
