      Re: Noisy/Crackling Line after a few hours

      after lots of arguing and persistence i still haven't got anywhere

      i borrowed a router from someone and it turns out it's not actually the router which is the problem. it's something else

      can a faceplate mess up over about a year? would it help if i bought a new one as it seems to be the connection (no crackling in the test socket)...

      Can you comfirm that with a new filter pluged in the test socket and with a router and phone pluged in this filter there is no problem. I 'm just confused about your last post and the no noise bit

      Not usually but it happens, which is why I raised the possibility earlier.

      Like everything these days, faceplates are manufactured to a price. Inevitably, components will degrade and fail. An Openreach engineer once told me they expected their faceplates to last 5 years. Maybe Brian has an opinion on this.

      Yes they can fail, but it's easy to check filters be replacement.
      To get back on track with this problem.

      (1) If after replaceing the filter, the line is noisy and the BB performance is poor then it could be the router. In this case the router has been changed and the fault persists.

      (2) If the line is clear at the test socket when no router is connected, then it is time to call your ISP and go through the process of capped speed, new routers and everthing they throw at you untill they agree to get Openreach involved.

      (3) If you are luckly and the line is noisy all the time, router or no router, then in this case you can call BT and get it fixed.

      My understanding of the latest info is that the problem goes away when using the test socket. That would appear to point to a faceplate or wiring problem (not the router as that's been swapped) so I'm not entirely sure I understand your three options


      @bigviv

      Can you confirm that the crackling problem isn't evident when plugged into the test socket? And does this include when a router is plugged in too?

      yes sorry.

      (4) If the fault is no longer present when using a new filter and with any extension wiring disconnected, then you need not call anyone, you need to refit the filter faceplate with the extension wiring disconnected and see if the fault clears. If it does, the fault is in the extension wiring, if not it is the faceplate filter.


      For the record my money is on a frozen up drain hole in a box somewhere and before Openreach get to it the sun will come out, the box will drain, and the fault will clear itself.

      thanks for the help guys

      hopefully it's the drain hole, will deal with the problem for a while and see what happens

      tried several things just now with no resolution...

      any ideas on what to do next? there are a few errors through the test socket so i did the BT phone check and the phone line appears to be fine.

      shall i run it for a bit back using the filtered faceplate? it's getting more and more annoying

      Re: Noisy/Crackling Line after a few hours

      So, with the faceplate off, and the router connected to the test socket, there is no crackling and no loss of speed? Can you confirm this?

      If that is the case, then it is your faceplate/extension wiring.
