And I'm still getting a very flaky connection in the mornings when I power up. VM sent me a letter 1st March apologising that the fault is still ongoing. And they will "contact me in a few days".... they haven't of course.

I know you want to turn your connection off every night, but why don't you put the hub on a timer so it comes on before you need to use it to give it chance to settle?

Why don't you move the modem so it doesn't need turning off?

And I am not alone in having this fault, it's all over the country.

Re: Think Broadband Ping Monitor Results (POST YOURS)

I'm not sure why I'm getting these episodes of packet loss or apparent disconnection. The SH3 config file has not changed nor has the software version, so I am assuming a temporary or developing fault. Those latency spikes are not due to activity at this end either.

I see that others are getting similar issues. What is VM playing at?

Re: Think Broadband Ping Monitor Results (POST YOURS)

Looks like an issue further into the network with the amount of customers seeing the same thing.

Virgin still not even acknowledged this new round of random packet loss

Re: Think Broadband Ping Monitor Results (POST YOURS)

That TBB is pretty much similar to mine. I really don't know what is going on with VM. My other BT circuit TBB is fine.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Just had this happen overnight. No config change, just a lengthy outage.

Re: Think Broadband Ping Monitor Results (POST YOURS)

I went from 16 to 24 downstreams last night in CB24, i guess it was only locked onto a few channels between 2am and 4am looking at the graph.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Something odd happened early this morning:

https://www.cableforum.co.uk/images/...2017/04/16.png

My IP number hasn't changed but a small packet loss seems to have stopped and the latency improved a bit.

Re: Think Broadband Ping Monitor Results (POST YOURS)

I wonder if the improved latency is a side-effect of things being knocked off the network.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Had a small outage earlier. Rang 150, automated message with "We are improving our network in your area". Oh good, perhaps being moved to a new CMTS. Anyway, connection has come back up but there's been no changes as far as I can tell. Oddly, there is two different CMTS MAC's in the network log. One a Cisco and the other a RiverDelta, which is the one that I think I'm still on. Not sure what's going on there.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Connection went down again about 20 minutes ago. Back up and now on 20 downstream channels and 2 upstream. On a Cisco CMTS, presumably cBR-8?

Re: Think Broadband Ping Monitor Results (POST YOURS)

I was told that our "local fault" was cleared yesterday, but the situation hasn't changed for me..

Re: Think Broadband Ping Monitor Results (POST YOURS)

Seemed to be an outage here last night, didn't get connection back until I rebooted the modem (router in modem mode).

Can't see any changes, same down / up channels etc
