Hey guys,
Can any of the plusnet team take a look at my connection please? i am experiencing packet loss. Running multiple ping tests to different IPs such as BBC, Google, Plusnet etc using the " -t " command to keep it continuous i am seeing packet loss/drops or "request timed out"
I can also see it in my teamspeak server looking up the connection info and it stays above 1% packet loss.
What's strange is when looking at my ping in teamspeak during my training period and roughly a month into when my connection was enabled i used to get 8ms ping and zero packet loss even when using some bandwith such as downloading updates in steam. Yea i am a gamer so that's why ping bothers me lol. However when my other half decided to unplug the router a couple of times to plug in the hoover i noticed slightly lower sync speeds. Yea i know DLM kicking in and ive told her off for doing this, however at the same time i noticed my ping went from 8ms to now 17ms along with with this packet loss so thats double the ping and packet loss so something does not add up.
So i've purchased and tried new Rj11 cable which is 0.5 meter to lower the attenuation/length and even tried 3 different microfilters including a faceplate filter all using the test socket. I am still getting the packet loss.
The SNR margin strangely has decreased from around 8 SNR to now 5.8 and bounces around from 5.8 to 6. I am wondering if it's the SNR margin that's causing this as it's slightly too low now and this is why i am getting packet loss thus causing the higher pings. Can anyone check this out for me and check if i am getting any significant errors on the line which i am guessing i have.
I am not far from the cabinet which is Cabinet 4 serviced by Wadsley bridge. So 6 SNR should be fine so perhaps a fault on the line causing noise?

Well still no reply from anyone at plusnet i guess. So i have the Vigor 130 modem installed, i noticed i was getting errors on the line while my SNR was hovering around 6. I changed my SNR to 9 and looked at my connection and like magic the errors seemed to have stopped or at least no where near as frequent. Only problem is during and sometime after my training period i had super nice low pings 8ms on team speak etc but i've kept the higher pings now the line seems stable 16ms. And my connection is in sync at 67 Mbit/s which is quite a drop from the full 80. How can one disconnection of the router cause this? I might have disconnected the line quite a lot since this happened though to change things like microfilters to resolve the issue, tried a different router etc.

*sigh*
Okay scratch that i'm still getting errors on the line and packet loss. Even at 10SNR which should be well above average. I'm starting to think there is a issue on my line causing noise/intolerance. at 10SNR there are less errors compared to say 6. At 3SNR and i get some real bad error counts. So going to leave it at 10SNR for now, could go to 11 with the vdsl snr +50 command but i doubt it will change much. I'll see where my BBFC takes me once some one from the faults team picks it up. Which might be monday now?

This is getting beyond a joke now. So i tried to fix things with another modem + router and my connection has gradually got worse. It seems DLM has taken over trying to fix/stabilise my line by constantly bumping/banding my line and i'm now fixed at 13 SNR and can't change it. Packet loss is now around 5-10 % and pings spiking now and then making gaming just not a great experience at all. Which is what the connection is primarily used for.
This is my speed estimates:
"We estimate your broadband speed should be between 57Mb and 76.4Mb and your minimum guaranteed access line speed is 49.7Mbps.
Downstream: | 44.6 Mbps |
Upstream: | 19.31 Mbps |
So as you can see i'm well below the estimates and now below that guaranteed line access speed. This should ring alarm bells to a fault on the line. I'm guessing REIN fault or something because it seems to be a noise related issue especially with DLM pushing my SNR up.
I've had a fault ticket open since tuesday using BBFC explaining the issue but it's not being picked up yet. I will be ringing monday morning. I'm just surprised i've had no one reply to this thread.
Here's what ive done so far;
Connected to test socket
Tried multiple microfilters ( about 3 different ones)
Tried another RJ11 cable
Even tried other ethernet cables (also doing this all with a wired connection, I don't use wireless unless for mobile devices/smart phones)
Tried a Openreach Modem (Huawei Echolife HG612 B3)
Tried another modem (Vigor 130)
Also tried another router (Netduma Microtik router)
Still having the same issue which is increased pings (initially had around 8 - 10ms ping) Now 25 - 30 with huge spikes hitting 140 ms. Also with packet loss. I'm going to assume the ping spikes is because of error correction kicking in which causing latency. Either way the line is bad and i think i need an engineer. Any chance i can get my ticket escalated because we are going to be nearly full cycle soon and a week will have gone by. Passed the 72 hour timeline ETA.
P.S just like to say i've put everything back to the original config which i had since i was connected, So Home Hub and same RJ11 cable and microfilter in the test socket. Will leave like this for testing.

How is your phone line? Have you tried a quiet line test - dial 17070 option 2?.
Have you reported a fault?

This is the only thing left i can do, Not got a house phone but i might buy a cheap corded one just to test to see if i can hear any noise on the line. Thanks for the help and yea i reported this fault on tuesday but nothing picked up yet from faults.
This is what my connection looks like currently at 13SNR
And this is a trace to get pings from bbc.co.uk;

Which router (s) are you using?
Not many allow the user to alter the S to N ratios.
I *think* I remember both Fritzboxes and Asus VDSL modems have suffered from packet loss due to firmware issues and compatibility with OpenReach's VDSL implementation.

Home hub that plusnet sends out
Vigor 130 plus a netduma router.
Open reach modem which is same make as my cab.
And a tp link archer. Cant remeber model off top my head. All different combos did the same.

Just to clarify:
Which router is in use On the TBB ping graph picture ?
Is the router responding to the TBB pings are some other device on the LAN?
Is the packet loss occurring on the first hop between your router and PN?

Packet loss is happening on the third and fourth hop which is after my netuma router and then hub one. You can see above i posted a quick tracert cmd run. 192.168.88.1 is my netduma and then the hub one is 192.168.254.1. I get zero packet loss pinging these devices it only happens after e.g from the modem to the internet. Tried a ppoe connection from my pc to vigor 130 and it still happens. Im 100% confident its not based on my side.

The tracerts do not show any packet loss to the BBC destination IP address.
Some of the intervening nodes are not responding to all the pings but they are all forwarded on to and responded to the by the BBC servers.
12 31 ms 31 ms 31 ms 212.58.246.79
From previous PN response to complaints of packet loss it appears to be normal behavior for "hiper04.sheff.dial.plus.net.uk" to not to directly respond to pings when busy. The device is sending the packets onto the downstream servers.
However, your TBB ping graph does show packet loss between the TBB server and whatever is responding to the ping.
I guess this could be a Red Herring but, I see from the netduma forums:
"if you're having trouble with packet loss on ping plotter it's because the duma uses a packet prioritization that drops packets instead of buffering them to reduce bufferbloat (excess ping) It's perfectly normal, no need to freak out"
