Check my levels please
 

Hello ,

I seem to have an intermittent connection with Several T3 timeouts on the upstream and several loss of synchronisation.

I have had a technician come out to me and he checks the connection and says everything is fine and then leaves, I have attached my logs below , I draw your attention to the T3 Timeouts on all the upstream channels and the Loss of synchronisation errors.

is there something you can spot that is wrong with my connection?

I have rebooted my router so the data is recent over 48 hrs , if you can spot anything I will give virgin a call

Thanks in advanced

Re: Check my levels please
 

First thing I can see is there looks to be a SNR problem!
Look down both columns Pre RS Errors/ Post RS Errors.
Normally Post RS Errors go down to 0 after a reboot, increasing over a short period is signs of problems.
The bad news is if SNR problems confirmed this at times becomes a thanklesss job finding where the problem lies. (Engineers problem)

Re: Check my levels please
 

Does this suggest that it's prudent to do a reboot every so often to get back to zero?

Re: Check my levels please
 

Personally, I collect those values very frequently. Then apply a derivative function on top to get the value per second. So it's not entirely necessary for those values to be low to be useful.

Re: Check my levels please
 

Could this be why all the technician's say everything fine and just leave and don't bother to investigate ?

Does anyone know if virgin have senior technicians you can request to visit your CAB and actually fault find?

Re: Check my levels please
 

Ok, thanks.

Re: Check my levels please
 

It's knowing what course to take, chance a call @08.00 and hope you speak to someone who can organise a tech, post on the Virgin Community website to get an opinion or even wait here for a more knowledgeable person on this site?

Re: Check my levels please
 

The tech who visits you should do that anyway. They have a checklist they have got to work through and even if they think they have fixed the fault in your house they have still got to go to your cabinet, check the connections and the power levels coming down the cable. If he cannot locate the fault he then needs to investigate higher up the network and escalate to the networks teams if applicable. Have you checked the coax cable coming into your house and going into the shub to make sure it is fitted securely and no damange?

Those pre and post rs errors are a big problem and you need to get them back out to look at them. When they come round show them the stats and it will give them some motivation to get it fixed. If they can see you are on the internet and can get to google for example they'll think everything is ok. It might also be worth setting up a ping monitor as well to see how much packet loss you are getting.

Re: Check my levels please
 

Thanks All,

This is today's graph,

https://www.thinkbroadband.com/broad...bae18ea15f7ef1

this was yesterdays,

https://www.thinkbroadband.com/broad...b02-25-02-2021

I currently have a thread open on the Virgin Media official forums about my issues , the last technician did say there was a lot of water in the local cabinet and would report this to networks but I've yet to hear anything back , what does my pre/post errors actually point to (ie is it noise?) so when the technician comes I can show him , last technician i had out checked my cable -> CAB and they go to the cab and check it to my house from the cab and can't find anything , can they check my cable from the CAB -> House or can they test the network CAB -> Local node and the local area/network

Can i actually go to networks directly as I've already had 2 technicians out? is there a senior technician I can request to visit ?

They show me on there phone a page showing loads of different graphs what they say is the network in my area and saying its all in sync and my modem is following the network?!?!

My thread I have on the Virgin Media forum is below , just awaiting a reply , if your on there can you comment on it so a VM staffer can see it ?

Re: Check my levels please
 

If you need to book a 3rd tech out you can tell them you want to put in a complaint when you do it and you want somebody more senior to look at it (the principle technician). It isn't good enough to say that they can't find what is wrong. If they can't find a problem close to home then they need to be looking elsewhere or escalating it to someone who can. If they say they have checked and there isn't a problem on the network then you can tell them you want them to start swapping out equipment by process of elimination such as the cables, the connectors on the cables and the shub. Noise isn't the problem here, that would be reflected in some dodgy power levels, it is a dirty or faulty piece of equipment and could be something a trivial as a loose or dirty connector on the outside of your property but likewise in the cabinet.

If I were you I would clear those rs errors from the log and see how it goes over the next couple of days. If the cabinet has been report to networks it would have been sorted pronto and the weather has been nice over the weekend for it to dry out. I imagine they will have replace any wet connections so now is a good time to see if whatever they have done has fixed the problem. If not, make another phone call.

Re: Check my levels please
 

It is getting worse because you are getting t3 timeouts across more upstream channels now. I firmly believe it is a cabling issue to you. To have those t3 time outs on the upstream and all those rs errors on each downstream channel there would have to be a major network fault which would affect loads of people and they would have picked up on it pronto and fixed it. Have you rebooked a tech visit yet?

Re: Check my levels please
 

Technician booked and is coming tomorrow between at 8AM-12PM

First call there automated tests wanted to reboot my router , 2nd call I spoke to someone and I explained I've had 2 pervious technicians out now and I requested a Principle technician and she was going to send a new router , she went away did a few checks while I was on hold for about 4 minutes , came back and booked a technician to visit.

My downstream/upstream stats after 5 hrs of uptime on the router , presume there still bad , my friend in Yorkshire who lives about an hour from me has a few weeks uptime on his Hub3 - Few hundred Pre RS Errors on all channels and no Post RS errors on all channels , is this what I'm aiming for?

Any ideas on what I say to the technician to help him , I haven't had the cable/equipment replaced in my house , do I explain what they have done in pervious visits or can he check on the pervious job sheets

are Technicians timed on jobs timed? i.e. they have a certain amount of time on a job?

Re: Check my levels please
 

Show him your BQM graphs (might need to print it COVID social distancing and all!) and explain the inconsistency of it.

Tell him what has been replaced and what hasn't, and any fiddling you've done (ie, if you've swapped attenuators, swapped the modem onto the V6 cable to rule out a dodgy cable between the splitter and modem etc.)

I had really similar problems that ultimately took an amplifier replacement to sort. It takes a lot of browbeating to get them to look that far up the chain (or them replacing everything up to the tap, as was my case). Intermittent faults like this only get spotted by some customers, and VM's monitoring doesn't notice it as well as it should.

Hopefully your issue is just a damaged cable in your home or garden, and the engineer can put a new one in easily.

Re: Check my levels please
 

they do have an allotted time because they obviously have to make another visits during the day however they are allowed ample time to investigate and repair your fault which includes a cup of tea/coffee and a chin wag.

As I mentioned before, his time also includes a trip to your street cab and checking the power levels at the tap point (which are very good). Show him the rs levels and tell him you can reset them now and they'll be in their hundreds again by the end of the day. It shouldn't be like that on every single channel and there can only be a a few reasons and explanations as to what is causing it. It is all about providing him with the information and data he needs to troubleshoot and make a definitive diagnosis.

Re: Check my levels please
 

From experience though when the problem is caused by another customer allowing a signal back onto the cable. Tracking down a wayword customer is a time consuming business!

Re: Check my levels please
 

Technician has been and gone , checked my line with his device , showed 5 graphs most of them amber or red in colour.

checked the cable coming into the house on both side of the wall , no problem

Made a call to networks who checked the cab and found no noise coming from the cab

he checked the CAB and confirmed a dodgy connection which he's fixed..

he confirmed Post RS should remain at 0 , said there was nothing more he could do , but said Virgin are delivering me a new router today , said to activate and try that and see how it goes

I think if the problem is still there is to open a complaint on the virgin media website

Re: Check my levels please
 

New router installed and activated - will post stats in the morning

Re: Check my levels please
 

and........................

Re: Check my levels please
 

Sorry , been busy recently,

They sent out a team manager/Leader who checked my connections and couldn't find anything wrong with it , he made a comment that post-rs colum tells you how many errors have been corrected , but did notice the cabinet needed rebalancing and he would ask networks to do it , a few hours later a noticed a VM network technician at my local cabinet who rebalanced it and i spoke to him and was very helpful confirmed that Post-RS Errors should be 0 or as close as they can get it

The stats are taken with 5 days of up time , We had a call a few days ago from a manager who we are phoning back

Re: Check my levels please
 

Wrong, the post rs-errors column are the number or errors which remain after the shub has attempted to correct the errors. If for example you have 10 pre-errors and 3 post-errors, it means 7 were fixed and 3 remain. When this happens the post-errors are basically dead data and need to be re-transmitted again which means your data transfer takes longer because things are having to be sent twice. Mine are 0 across the board and a) you shouldn't have them across every single channel and b) not in the tens of thousands. You have also got T3 timeouts on every upstream channel.


When you ring them back tell them and ask them what they are going to do to fix it. If they give you some bullshit answer of "we have checked everything and are confused as you are" tell them they can start replacing everything starting with the cheapest thing first and working their way up until they find out what is causing it.

There are 5 people that I know of but I think only one of them will be able to help. I'll send him a pm and see what he thinks.

Re: Check my levels please
 

Thank you :) , at my request the last technician left me some replacement cable for inside the house , is it worth swapping the cable over and seeing if this makes a difference ?

It's got the connectors on it at both ends - Ready to go

Re: Check my levels please
 

Put the cable in a drawer or cupboard and say nothing ablout it. It is not the issue. The engineer should sort out your problem when he comes.

Re: Check my levels please
 

Good Point - Thanks will do !

Re: Check my levels please
 

that is the kind of thing i was talking about when I said they should start swapping stuff out; the operative word being "they" and not you.


The VM guy I pm'd sends his apologies. He has reviewed all the info and can't do any more for you above what the techs have already done.

Re: Check my levels please
 

Re: Check my levels please
 

Have you tried posting on the VM Forums - https://community.virginmedia.com/t5/Speed/bd-p/Speed

Admittedly if a VM staffer on here has taken a look, that might be overlapping a little, but you never know.

Re: Check my levels please
 

Re: Check my levels please
 

It was the ability to pass things up the chain, that I was getting at.

No arguments with your point about the expertise on here, although it's not impossible to find that on the VM boards.
