Broadband dropping out regularly in the evening / morning

Go to solution

My BT hub regularly loses internet connectivity, often late at night before I go to bed, frequently in the middle of the night and often first thing in the morning. This has become such a pain that I wrote a little monitoring utility to track my broadband connectivity in an attempt to understand what was happening. Last night for example it reported I lost connectivity at 02:22, regained it briefly, lost it again at 04:38 and it was still faulty when I got up in the morning, returning only at 07:40. I've had an engineer visit; he checked the hub (it's a BT Smart Hub Type A), the in-home wiring and everything out to the pole outside my house and found no problems. But that hasn't fixed the issue. This only used to happen occasionally, but now it's pretty much every day. About the only thing I can think of is that now that Autumn's here the house gets a bit colder at night when the heating goes off, but IMHO that shouldn't affect the operation of the hub. Has anyone else experienced anything like this?

your heating going off/on can cause electrical interference which may caused the hub to drop internet connection.  is hub just dropping connection or is the hub actually resetting?

As far as I understand it the connection is dropping. I get the flashing orange light when it's disconnected. What's odd is that when it starts misbehaving it typically goes into a cycle of dropping the connection, reclaiming it 1 to 3 minutes later, then dropping it again. For example last night my logging utility showed the connection dropped and restarted over 70 times between 04:38 and 07:40. The previous night it dropped about 60 times between 0:28 and 03:35. This is clearly not caused by electrical interference as the heating (and most of the other things in the house) were not operating when the trouble started. I'm suspecting some sort of problem with the hub, but can't be certain; I may take a look at the hub management console to see if there are any sort of logs that throw light on what's happening.

check hub system logs filtered 'WAN' and that should show drops in connection.

have you tried just connecting to test socket with filter eliminating your internal wiring to see if problems still happens?

you could try a factory reset of hub by pressing the recessed button on back and holding until lights flash

if resetting hub does not stop dropping connection then phone 150 and ask for replacement hub

Hi @nwlondon ,

Did you manage to get this sorted? Can you let us know if you're still having problems.

Cheers

Re: Broadband dropping out regularly in the evening / morning

No, it's unresolved. I had an engineer visit, he tested the cables and the line out to the pole across the road and found no problems. However my internet regularly drops out at about 00:27 just as I'm trying to watch the end of a video before going to bed. It then cycles up and down at intervals of a minute or two. Sometimes it's still dropped out first thing in the morning, and occasionally it drops out during the day for a minute or so. The router log reports "link down" WAN events. I called BT again and they promised another engineer would visit last week (he didn't) but they sent me a text saying they'd fixed the problem - but they obviously haven't. As it's mostly OK during the day when I'm working I've avoided calling BT as I don't have time during the day to sit on the phone for ages waiting for the call centre to talk to me. But I'm going to have to bite the bullet and try again; this time I think I'll make a fuss and demand a new router because if the network is OK and the wires are OK what's left?

Thanks for getting back @nwlondon .

Sorry you're still having problems. I can help. I'll need a few details so I'll drop you a private message now so you can get in touch.

Re: Broadband dropping out regularly in the evening / morning

Thanks for the offer David, but I had some free time as it's Saturday morning and called the helpdesk; plus I have had some more dropouts some of which weren't in the middle of the night. Another engineer visit is scheduled for Monday. Talking to the helpdesk guy suggests that part of the problem is in the exchange because the connection vanishes regularly at half past midnight every day.
