Broadband Dropping Out Approx Every 24hrs

[pscraven]

Hello, I have a repeating issue with my Broadband and I'm struggling to get a satisfactory resolution via normal BT support routes so coming here for help (pretty please).

I've had reliable BT Fibre 2 for a couple of years approx 70Mb (Down), 20Mb (UP). At Christmas I was cut off by BT in error and service restored by BT on 6th Jan 2023. The new service is the same Fibre 2 under a new account but this time BB only service (ie no telephone).

Since 6th Jan, my broadband now drops every day for about 5 mins, usually around the same time 12:15- 12:30. I have tried several things and had several BT visits to look at the router and the line.  The line checks out OK and I have removed a couple of devices from ethernet ports as the OpenReach engineer suggested doing so (not entirely sure why?).

Night before last night at 11pm reset my router to factory default to see if the problem reoccurred at either the same time or after 24hrs.  Result was it went down again today at the same time (12:05:26 to be precise).

BT seem a little reluctant to investigate the router logs which surprises me and instead are suggesting it may be electrical interference  or something they refer to as 'RAIN'.  My suspicion is the problem is either in the home with a rogue device or with the switch in the street. Please can anyone interrogate the logs to see what's going on and provide any simple advice on what to look at next?  I will add the logs to the post shortly. Thanks in advance!

The logs won't give any indication as to the cause of the problem, all they do is confirm the date and time of the disconnection.

It is possible that it is REIN (repetitive electrical impulse noise) that is causing your problem.

It's an odd time, but do you have any electrical items switching on or off at that time?

[pscraven]

Thanks for the response, nothing locally switching on/off within the home at that time.  The logs confirm it is a daily occurrence, but the time does differ slightly each day (+/- approx 30 mins).  I agree that REIN (thanks for the explanation) could be a cause  however it wasn't an issue prior to 6th Jan 2023 when my service was reinstated. That could be a coincidence, but feels unlikely as its pretty much like clock work every day now and yet was rock solid prior to that.  The only difference in the service I can see is its now BB only. Do the logs not contain any useful information prior to the disconnect?  I also wonder if this effects my neighbours and if there is any data available to BT to identify as such? 

[licquorice]

No,the logs won't give any indication of a line dropping other than the drop itself..

12:05:26 22 Feb. DSL Link Down: duration was 84626 seconds is the only indication and it shows a line drop that restores 12:06:13 22 Feb. DSL Link Up: Down Rate=69426kbps

Duration is uptime since the last disconnect.

[pscraven]

Ok thanks.  So its an approximate time of day issue not an exact time of day one.  I would have thought if it were a issue related to a timer it would be exact rather than approximate? Therefore it could be another trigger such as a sensor? Is there a BT helpdesk of forum related to REIN does anyone know? 

[rbz5416]

When you were reconnected did you retain the same Hub or get a new one?

If it's the same Hub that does rather suggest the line rather than the local environment. If you haven't already you could try relocating the Hub to a different room with a longer RJ11 cable.

An AM radio may indicate a REIN problem:

You could also try turning off all appliances, including central heating for an hour or two either side of the problem time to see if that helps.

Hi @pscraven , I'm having the same problem since mid December. I then switched from BT to Sky and the problem started. I thought that switching back to BT would solve the problem, but it hasn't.

With me the drops are around 11-12 in the morning and last for a minute. The log file from the router shows the same.

BT engineer came last week and changed the socket on the wall, but that hasn't fixed anything. I'm now trying with the router at the different place in the room, but no difference. Tomorrow morning I plan to disconnect the ethernet cables from the router and see if that makes any difference.

Could we be neighbours? I'm in Milton Keynes.
