Disconnections after FTTP upgrade.

[longedge]

I upgraded to FTTP on the 21st Nov. and since then i.e. last 9 days, I've had 5 disconnections. The last one was about 01:19 this a.m. and the log shows "WAN connection WAN1_INTERNET_ETH disconnected.[ERROR_NO_CARRIER]".

After FTTP became available in my area, there was a very noticeable change in my FTTC service and when my fibre was installed I was on day 66 of continuous uptime.

TBH the disconnections have so far not bothered me but I am wondering whether they are just the start of more serious problems. I don't know what the possible causes are for the disconnections and indeed whether I should be reporting a fault so I thought I'd ask here for guidance.

That seems quite an odd one.  Normally FTTP is stable and pretty solid.  I wonder if you've got a faulty ONT.  Do you know/can you find out what happens with the lights on your ONT when it disconnect?

[MisterW]

If there's no change in the ONT lights, then

1) check that the ethernet cable is securely located and locked in at both the ONT and router

if that has no effect then

2) try another ethernet cable

3 of the disconnections were around 1a.m. last night at about 12:40 and 01:19 so watching what's happening isn't possible (I'm too old for night time vigils ). I only know about the other two disconnections because they showed up on my ThinkBroadband broadband quality monitor.

I will check the ethernet cable. It was brand new and previously unused, not to say that there's not a fault but I doubt it, although I understand the inference from the error log.

I was wondering if there is some sort of load balancing going on but I don't know if that is even a possibility?

[MisterW]

The early hours are when BT wholesale tend to schedule any maintenance, so that's a possibility...

[pjmarsh]

Those three could be maintenance work somewhere else on the Openreach network given their times.  These do happen from to time.  Nine would be excessive though.

Edit: Sorry, I miss remembered, thinking you'd said 9 disconnects, rather than 5 in 9 days!

[longedge]

Just to be clear - 5 disconnections in total.

3 overnight around 1am and of those 3, 2 were last night.

The remaining 2 were during the day and as I said, I didn't notice them so for now it's unimportant and just a case of whether I need to 'nip it in the bud'.

Hiya @longedge 

I can see the drops on your line here; http://visualradius.plus.net/visualradius/generated/image17013528181433.png and I want to run some tests. 

Are you using our router? 

[longedge]

Thank you for that. Only for this forum so go ahead.

Edit - I read "Are you using your router". Yes PlusNet Hub Two. Previously used on FTTC.

[SammyM]

I've sent you a PM with what I need, can you pop it over? 

[longedge]

@SammyM I haven't got a PM but I received an email to say you've raised a ticket which I've reviewed.

[MisterW]

I haven't got a PM

I have though, oops!

[SammyM · Accepted solution]

Haha Sorry about that Have you got it now?

[longedge]

Thanks, reply sent.

[longedge]

Very many thanks for your pro-active intervention. Excellent customer service as always .

p.s The 'fix' is that we've agreed to monitor the connection as all the tests that have been done showed no faults.
