150M : Repeated Cut-outs. What info can I collect to convince Virgin of the problem?

Cheers. I'll try that. This seems the optimal situation for me because it's both a temporary working fix for now with the prospect of a proper fix soon all with minimum effort from me.

Might be worth setting up a Thinkbroadband ping monitor as swoop suggested, if you don't already have one running. Would show the dropouts every 34 mins whilst in modem mode, on the graph that it produces.

As an aside, I've got one of the SH3's coming on Friday. Pretty sure I'm still on an old Motorola BSR 64k (If anyone knows about the Telford headend could confirm?), so hopefully not letting myself in for a world of pain

If you have a superhub 3 and can only see 12 downstreams then you are on a BSR or a 10K old type ubrs 16 to 20 downstreams then your on a new ubr

Ok. I have switched to router mode. Setting up the ping monitor. Let's see what happens.

So i've created it. How does it actually work? I assumed it ran from my machine. But it's just a website. Do I need to keep the tab open and it just makes the occasional request on the client?

You just go to "your monitors" on the website and the graph appears. It pings your machine 24/7 but uses negligible bandwidth.

e.g.



To post it here, click "generate graph" and then "small graph". To make it a snapshot and not a realtime graph copy and paste all after ' src=" ' up to ' " /></a> '

It will look like [url]http://www.thinkbroadband.com/ping/share-thumb/e389e84fe786e310a9e08ed5717793dc-11-10-2016.png

No cut outs but this doesn't look great:



Could my firewall be blocking it?

[Jon22]

Yeah, I think you have turn the firewall off when in router mode to get it to respond to the pings that are being sent to it.

I'll see. So far I am doing ok, no cut-outs, I'll give it a while and tomorrow but if so I might be ok...

Ok just hit another timeout..

Nothing in network log. I'll have to phone them tomorrow.

It was weird this timeout lasted longer but seemed to retain a snail's pace of connection instead of outright failing. Previously it would just fail. Here a page would take 5 minutes to load...

There is a tweak required for Vm routers to show the correct graph..

It's actually a separate piece of hardware at think broadband. It sends a ping request (A small data packet that the target echoes back if pings are enabled) to your IP every few seconds and logs the response. The website provides a means of accessing that log in a graphical form for posting on forums.

Since it runs outside VM's network it is a useful guide to your accesses to the wider net.

Thanks. Got the SH3 earlier, have 12 downstreams and the wintelguy site says the CMTS is a Cisco. So 10k then?

Cisco 10k, with one of these supplying your downstream bandwidth.

Temporary solution; you'll be moved to newer kit as soon as it's sorted.

Thanks Igni. Going slightly off topic but are the original CMTS replaced with the same make? So Cisco 10k to cBR-8, Motorola BSR to Arris E6000? Or are they just replaced with whatever is available at the time?

I think the SH3 lists the CMTS mac address in the network log. Copy it into the search box on this site: http://wintelguy.com/ and it should give the manufacturer of the CMTS.

THanks for the link there.

Anyone got any information on "River Delta Networks" which the CTMS comes back as for me.

Motorola I think own RDN now, is it a CMTS that is good, has issues, because my connection certainly does.

Doesn't seem to be a pattern from what I've seen, though could be wrong.

Old Motorola BSR 64k. Will be replaced at some point soon with the newer type.
