Internet dropping out every 5 minutes!

Hello folks

So I've had problems with dropping connections over the last few months but this evening it seems to have gone crazy.

It'd dropping out every 5 minutes!

This is a wired connection. I have a Hub One. And I can very clearly see the reassuring blue light replaced by the flashing orange 'B' every few minutes. It then goes through it's process of reconnecting, but then disconnects again a few minutes later.

What could be going on?Huh

Please help!

Here's a bit of the Event Log...

Re: Internet dropping out every 5 minutes!

@thurrafork This looks like a continuation of the previous problem - as you were advised at the time, it now looks as though you need to raise this via faults.plus.net.

Re: Internet dropping out every 5 minutes!

Hello again

And now everything is fine again!

It was disconnecting like clockwork every 4 minutes for about 16 hours, and then last night it reconnected and stayed connected!

Nothing changed. I had attempted no fix. I had not wiggled the wiring.

Yes, this is very possibly associated with some ongoing underlying problem that may well rear it's head again, but it's so odd.

Previously it would be dropouts. Random. At it's worst a few times a day.

But this recent episode was unlike anything previous. It was so regular. It was so cyclical I was starting to think it might be some kind of overheat>shutdown>cooldown>restart>overheat pattern, but I just don't know.

Then I thought it might be something to do with the "PPP LCP Send Termination Request [User request]" log event, which always preceded each disconnect. This seems to have appeared quite often with Plusnet/BT connection issues, and was often found to be down to a faulty router.

I just don't know.

I have a boxed BT Smart Hub rattling around somewhere, so if problems reappear I might try swapping in that.

We'll see.

In the meantime, my unskilled speculation aside, does anyone have any notion as to what could cause this kind of 4 minute cycling disconnect pattern?

Thanks.
