Re: Think Broadband Ping Monitor Results (POST YOURS)
 

2 techs have been out, new PSU, new SHUB2AC, all levels checked, etc.

What's the most annoying is that it's not the same every day. Not even the same timeouts, etc. And some days have no faults shown in the network log at all.

I've tried to get solutions via their forum to no avail, and explaining on the phone is hopeless.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I know you have valid reason for doing otherwise but does the same still happen if the SH is left switched on? - merely for diagnostic purposes.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

It didn't happen when I left it on 24/24 for 3 days. But sometimes it doesn't happen for 3 or 4 days anyway after an overnight powerdown.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Then surely the next thing in the diagnostic process would be leaving it on 24/7?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

One of the techie bits of advice was that turning it off should not cause these problems, so it was up to VM to diagnose and fix the problem outside our home.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I agree but why do you have an aversion to conducting your own diagnostics so you can reply to them with evidence?

Seems total stupidity to me but then again, what do I know?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I send to my own thread on the VM forum: thinkbroadband graphs, network logs, levels logs, status logs for EVERY occasion this fault appears. As they requested.

A new PSU, new SHUB2ac, 2 tech visits... and they appear to be none the wiser. As a telecomms tech myself I know how frustrating intermittent faults can be, so I am providing them with as much evidence as possible.

If I was not tech-savvy at all, would they expect the same?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Quite true but I note the use of the word "should". e.g. how many times have you seen a light bulb fail when you switch it on compared with a bulb failing when its on ? :D

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

So you've proved it happens every 3 or 4 days after powering down every night but not that it doesn't if you leave it powered on 24/7 as you've only done that once (24/24).

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

A VM guy on the forum said SNR was now in spec and the fault was closed. Ahem... it's still doing the same thing. And today we have only 1 upstream.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

You got some serious problems, try rebooting it again to see if you get 2 upstreams!

You have contacted the CEO office i guess?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

The second upstream just reappeared.

It's been a long period of the same problem, dating back beyond 23rd September when I started a thread about it on their forums.

http://community.virginmedia.com/t5/...up/m-p/2917052

It's not every day, but about 3 or 4 times a week. I've been posting them the relevant info as it appeared.

Long periods between responses from VM though. Moved to SHUB 2ac, new PSU, multiple checks... same fault.

Time to take it higher as you suggest.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Looking at your last few graphs the red part is in the night, i think you said you turn it off over night so what is the problem?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

It's after I switch it on. Around an hour of on-off-on-off connection. "It should not happen" is what I've been told. Plus lots of short periods during the day when latency shoots up making the connection unuseable.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Or, y'know, stop causing the problem yourself.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

It was not a problem until a couple of months ago. Then the problem appeared. So it is a problem that their equipment is causing. And they admit it.

"Cars should not crash" is an awful analogy.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Funny how good some people are at jumping to conclusions about things they don't understand.

At a guess you've been moved to a new CMTS. I had another funny when this happened to me a few weeks back, I was apparently in Newcastle according to geolocation lookups for a few weeks. Presumably an IP range recycled from oop-north.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Well let's hope it's an upgraded one.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

If you're on 16 it is one of the next generation ones.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

16? 16QAM upstream?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

He means if you're on 16 Downstreams then you're on the new kit, i only have 10 so i am still on Cisco.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Still only on 8.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I'm on BT and have over 2000 downstreams.

I was on 8 then it changed to 10 a few weeks ago, everything seems the same still congested in the evenings.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Can i ask you please how you know its like that 247 ? Are you using a whitebox or network monitor etc ..

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Phonecall from the tech who was here the other day:


"Node Black Porting at 11%, Networks involved, other customers getting the same fault in the area".

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

You were talking about an upgraded CMTS. I was referring to Coventry CMTS 16.

You have a modem that tunes 8 channels only.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I know this because I have tested at all times more than once since the latest speed up grade including small hours(if I'm up and about), evenings, breakfast, week days, weekends peak times and off peak times. Invariably I get those speeds.

https://www.cableforum.co.uk/images/local/2015/11/7.png

I am a keen speed tester, using speedtest.net, thinkbroadband, dsl reports and the Uswitch tester. I get similar results with file download tests.

---------- Post added at 21:44 ---------- Previous post was at 21:43 ----------

That is right, so I have no idea if I have been moved to an upgraded CMTS without some other source of information.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I can't say it's how I'd spend my time or if I'd be that bothered but to each their own I guess.

A reverse traceroute would work.

Willy waving again qas?:D:D:D

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I'm reliably told by VM Support that it's an Arris. All my 8 downstreams are QAM256, 2 upstreams are QAM64

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

You can check what CMTS kit you're on yourself.

You need to find your CMTS MAC address and enter atleast the first 6 characters into the link below e.g 00:1d:70 which reports back as Cisco for me.

I got my CMTS MAC address info from my network log page on my SH3.

So my IP address changed for the first time in nearly 2 years. Was getting some bad congestion in my area and now it's worse:

Down to 8 channels as well (Was 10).

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

You're testing on a Virgin Media speed tester, the issue is with Virgin's connectivity to other networks in London.

---------- Post added at 09:49 ---------- Previous post was at 09:48 ----------

It's not the monitor. The monitor is fine.

---------- Post added at 09:50 ---------- Previous post was at 09:49 ----------

Both LINX and NCUK are fine. The same cannot be said for Virgin Media's connectivity to the LINX LAN.

I'm unsure why they seem to struggle so much with capacity on their London / LINX connectivity.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Hmmm I'm still struggling to interpret the following TBB results on two Brighton nodes:

Howver BN37N_ has SH3 16ch and SH2AC 8ch running concurrently -

Brig19 SH3 Ping

Brig19 SH2AC Ping

However BN35L_ has only SH2AC 8ch running -

Brig22 SH2AC Ping

Which appear to indicate the routing on 2 different Arris for same SHub model type is different and between two different SHub models on same Arris E6k? As you'll no doubt enlighten me way before I overtax my limited technical capability to speculate further then I'll just patiently "ponder" in the meantime...... :dunce:

No hump for me, just a terrible service:

http://www.thinkbroadband.com/ping/s...08-12-2015.png

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

There are a number of subnets / DHCP scopes allocated to each chassis. Note I said chassis not line card or node. Some of them may be from affected supernets while others aren't.

:)

EDIT: The model of Superhub doesn't matter, by the way, just a case of whatever the CMTS had available and was first on its list at the time.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

I do have one question though ever since i had my internet installed and it being up and me using it my neighbors have said there speeds has dropped by a fair bit, is that to do with me?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Because they're cheapskates.

Oh wait, it's not even costly.

I'm surprised VM haven't gone with direct peering with NCUK yet, just to be able to show off uber-tight BQM graphs.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

It's nearly impossible to tell but you alone are not enough to cause congestion for your neighbours, it would be a cumulative thing and you would see congestion as much as them. If you're still getting full speed, it's almost certainly their issue.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Ah okay just seemed like a weird coincidence is all

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Thanks Carl, although I'm still pondering as I (naively) expected to see some change of IP at peering link in hops 6 & 7 below which was (and still is) identical at the time for both my Hubs? :

6. 212.250.14.202 tclo-ic-2-ae0-0.network.virginmedia.net
7. 195.66.236.240 linx-gw2.thdo.ncuk.net

Curious but will just have to wait another couple of months for a re-occurrence perhaps? ;)

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

You only see the outbound path with a Command Prompt traceroute. It's the return path that's having issues.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Get your own router, put the Superhub into modem mode and put it elsewhere in the property, turn the router off at night, leave the Superhub on with LEDs covered, problem solved.

Or start using parental controls if the kids aren't grown up enough to be trusted with the broadband and either cover up the LEDs on the Superhub or move it to a more sensible place than a bedroom.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

The only PC was originally in our bedroom so the modem was installed there.

Our twins have disabilities which mean they do not truly understand the passage of time.

The fault is known to the Network Managers (very poor signal to noise ratio in the area causing my symptoms, and others, in this part of the city).

And I suspect they will not go for the bodge approach by advising the use of a router and covering the LEDs.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

It doesn't matter how you run it, it's an outbound traceroute and that's the problem.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Traceroute by design can only see the outbound path. Remember how it works; it measures the time from when the system sends the UDP datagram or ICMP echo to when the TTL expired comes back. It only sees the node that sent the TTL expired, which is an outbound path router, so can't identify how those TTL expired messages sent by routers on the outbound path made their way back to you.

EDIT: If the humps are still there I can show you the respective return paths if you provide the first 3 octets of the IP addresses in question.
