Internet cuts off multiple times every night

[jaymul88]

Hi, looking for help with an ongoing issue, I'll try to include as much info as possible!

My internet has been cutting off multiple times every night for a while now. The last couple of weeks we get multiple disconnects every night which can be quite frustrating as I work night shifts at home and have to reload multiple programs every time it cuts out.  A rough timeframe seems to be between 5pm-midnight. Doesn't seem to happen much after midnight.

Its been ongoing for a few years but sometimes we can go a few weeks/months with no disconnections. 

It seems limited to only cutting out in the evenings, I've not seen it disconnect in the day time. 

When it disconnects it will be offline for a couple of seconds, the router will flash orange and then it will all come back on, so the connection is only lost for a few seconds at a time. 

In the past we have contacted BT over the phone, sometimes its helped and we wont have issues for a few weeks/months (I have no idea what they do but they remotely change some of the settings) sometimes it makes no difference.. We've had new router, new filters, new ethernet cables yet the problem still persists. 

I've looked up a lot of info online but I'm a bit wary about changing router settings as I don't have much knowledge about what I'm doing with it.

One possible issue is our phoneline, again I'm pretty clueless about these things so could be irrelevant, but a couple of years back we had windows replaced in the room where the router/phoneline is. Weirdly the phoneline was wrapped around the outside frame of the window a couple of times and it has a very old looking box with GPO and a screw on one side. When they replaced the windows they chucked the box inside and its been behind a cupboad with a lot of (unnecessary?) excess wire but both wires seem to still be connected. This box is VERY worn down and also has loose wires showing at either end. Could this be the issue all a long? If so, would this fall as my responsibility or BT? 

A little extra info: The router is plugged in to a Google mesh network, this is quite easy to monitor using the app and the issue seems to be coming from the router/phoneline not the mesh network.

Thanks in advance for any help.

the 'box' you refer to is just a junction box where the incoming openreach line connects to the internal wiring.  have you opened the box and see if there are ant loose wiring.  there should only be the incoming wiring and one outgoing wiring which should connect to your master socket

 please can you post the stats from your router (if hub enter 192.168.1.254 in your browser) and if  HH5 then go to troubleshooting then helpdesk and if HH6/SH2 then advanced settings then technical log information . 

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

enter your phone number and post results  remember to delete number   https://www.broadbandchecker.btwholesale.com/#/ADSL

Someone may then be able to offer help/assistance/suggestions to your problem

Hi thanks for reply. Unfortunately I don't have a landline phone to do a quiet line test. 

Here are pictures of the box:

As said in last post this was originally outside and has the incoming & outgoing still connected. It's difficult to think it could be the box as the problems are almost exclusively in the evening.

Here are some of the technical log information from last night. Must've had around 5-6 disconnects last night including while I was writing the original post, and no point posting todays as it hasn't gone off at all today!

No need to post logs it is the technical information not logs

A landine is the most basic tool in diagnosing broadband problems as most problems are caused by line noise

Looking at the photo of inside of box there has obviously been water/dampness causing serious corrosion and if mine I would gently clean all the terminals

If you post any more photos can you post here instead of links as saves going backwards and forward 

[jaymul88]

Thanks for quick reply, sorry about the pictures the files were too large to upload here. 

What would you recommend to clean it? Do you think this could be causing the issues?

I guess I should go get myself a landline today then!!

@jaymul88 Might be a good idea to edit out your Hub id as this is a public forum.

@imjolly  Will doubtless advise of I am wrong here.

[imjolly]

As I said if it was mine then I would carefully clean the terminals and get rid of the surrounding corrosion

Thankfully from your stats all the drops in connection have not resulted in a loss of connection speed

[jaymul88]

Nope, the speeds are fantastic! Just the constant drop outs are very annoying when working and it is only ever for a couple of seconds at a time. I will try giving them a clean and see if that helps.

Thank you
