Re: DSL Link constantly down

stsiopani · ‎31-03-2022

I'm having the same issue many others seem to have had here in the past with my DSL link constantly going down. Have had three engineers out and still the problem resides. The first one tried to fix a problem 50m away outside and the second replaced by master socket due to some visible corrosion. Are there any mods on here that are able to help? The problem is intermittent and the disconnects happen from every 30 mins to once or twice a day.

Here are the occasions it's been down in the past 2 days:

16:37:18, 31 Mar.DSL Link Down: duration was 347 seconds

09:13:05, 31 Mar.DSL Link Down: duration was 9156 seconds

20:41:51, 30 Mar.DSL Link Down: duration was 11214 seconds

17:34:19, 30 Mar.DSL Link Down: duration was 5166 seconds

16:06:49, 30 Mar.DSL Link Down: duration was 6825 seconds

Interesting your connection speed is still about the attainable speed and noise margin about normal 6db despite all the resets in connection.

With amount of disconnections it suggests something near the hub causing interference resulting in drops in connection. Have you tried connecting to the test socket with a filter (even if you currently have a filtered master socket) to eliminate your internal wiring a the cause of the problem.

What devices do you have connected to the hub?

All the mods can do is book another engineer. It just needs a competent and diligent engineer to track down the cause of the line problem.

stsiopani · ‎31-03-2022

I think I may have found the cause. I saw another post on here which mentioned a dodgy extension cable with a non lit surge protection light. It just so happens mine is like that. And, it's plugged into a power socket in the wall which seems to be suffering from corrosion on the contacts. The wall that the power socket it in seems to suffer from a lot of damp.

I may try replacing the extension cable and the power socket in the wall to see if that fixes it

stsiopani · ‎01-04-2022

Update: I've moved the hub to a different power socket and removed my powerline adaptors but the issue remains. I wonder if the overhead lines from my house to the telephone pole need looking at as I can't think what else it might be...

The only other thing to try is another BT Hub, in case mine is faulty. But the DSL link down event log errors suggest its more of a connection issue as opposed to a hardware fault with the hub

imjolly · ‎01-04-2022

have you now connected hub direct to power socket without any extension cable? have you tried replacing the rj11 cable with connects hub to master socket? have you tried a filter and using test socket and see if that makes any difference?

Yes, the hub is now connected directly to power socket. The RH11 cable got replaced when they replaced the master socket. I haven't yet tried connecting to the test socket - will try that next. They replaced the master socket with one that has a dedicated broadband socket and one for the phone - does this still have a test socket? I also don't have anything connected to any other extensions in the house (not even sure I have any extension wiring).

Yeah its a Mk.4 master socket and doesn't seem to have a test socket behind the backing plate

stsiopani · ‎01-04-2022

Yeah its a Mk.4 master socket which doesn't seem to have a test socket behind the backing plate

imjolly · ‎01-04-2022

if you remove the faceplate which just clips on then test socket is visible
