What is happening in south bristol? Can we get some help?

Just a brief message to ask what's happening in South bristol, I been trying to get my parents connection fixed for a long time there tv and streaming services are really effected. Mine up until recently was in a reasonable state. So I've been getting up and down profile changes every day is this normal? What isn't normal is the 15, 20 in one day after many 60 second resets it always goes back to bad within minutes or hours. 

 

Bqm shows constant packet loss, correctables shows 6 digits after reboot, but populates very quickly to the billions on my down profile. Parents 3.1 ds is over 10dbmv to high and gets double sometimes triple digit uncorrected on the 3.1 ds, numerous profile changes per day also. There bqm is terrible and has been for months. I checked for area for any work or faults on the phone says there is none. WiFi for them don't work hub will not let me change channel or frequency for the 2.4ghz, it shows try again, also won't apply the disable smart WiFi. 

 

Looked outside to check there f connectors for loose ones could not believe the state in there, disconnected line and fp attenuator just left there all tangled and not in good order. Let's be real the problems are network side. 

 

Some help would be appreciated, I've just setup 2 more bqm today at different local homes to show its not my internal line as senior engineer already confirmed good to the taps, yet sometimes vm ask about my asus gt-axe16000 which is nothing to do with anything or the qos I recieve. I will add some bqm and stats if anyone can see anything I can't as I'm a mere customer here. This is getting out of hand. Many thanks good day. 👍

    There is a gap in what we are reading in this thread.

    I don't see comments saying hours of disconnections occurred during the red periods of the BQMs.

    Do you understand what device the BQM is pointed at ?
    The graphs reflect a device that is not always on or not always accessible.
    I.E. not a VM Hub in Router mode or not a customers 3rd Party Router.

      Hi let me explain again as its confusing, the 1st 3 pics is my hub 5 ip at just after 5pm I put in modem mode so thats a different bqm chart. Data showing was due to my public ip being changed I just checked. 

      All the last pictures are a live 24 hrs a day running connection no turn offs or modem mode? My question was why is it sporadic to pings?

      Regards

        I still have no answer to why bqm (not the top 3) is showing data here and there instead of all day and night. its running all day last few days its showing no data, I'll have them check if your changing ip address.

    Just a quick sanity check.

    Are these connections all having total outages during the hours of red shown on the BQMs ?

      Hi no the first 3 pics, connection is in modem mode so should show no connection/data from hub ip, the rest active connection just show sporadic data.

    It will probably make no difference.

    About the symbol rate... What is it you don't like about it? 😊

      Symbol Rate as in 16qam 4 bit alot less than 64qam 6 bit.. why because there to many people for the network so it can just drop people's capacity bit per second so cmts can keep signal, so i am loosing udp packets everytime its like this. Its an area noise problem if its dropping all our mods which it is. like I'm no expert I'm just a customer but we have to try to research as you can see Virgin Media just doesn't answer customers concerns at all anymore, thats why ofcom again mentioned them as the worst in every metric especially customer service. They see no problem in having a 1 year problem, which was way better for the last 2 months hence I haven't posted at all, but its all starting again rotate people's profiles to shut up some for a month then shut us up next month. I've checked all on same profile and getting numerous changes per day. If its being worked on just tell us, then we dont need to bother the forum team.

      6.8 billion revenue on a post I read but infrastructure still copper to home and drop cables. 

      Don't know if vm cares but no ones using my Internet just me on a phone and all upstream dropped again.

        Oh, that is the data rate. Data rate=symbol rate*modulation.

        (The symbol rate is determined by the width of the channel.)

  • Hi Cardiff it's my friends mum, no its on most of the day if not day and night as theres kids with phones tablets computers etc, if you look at pic one where it goes off it stayed off for 3 days just popped on off again today. Ip address is the same.

  • Why do I have 4 sfid? Both our netlogs show continuously changing profiles, 20 t3 on the 3.1 docsis us, the rest won't fit in so I screenshot it. Cable Modem Status 3.0?

        Hi kath any word on the area please upstream has dropped on mine on all channels after being good for months, is this bad routing and or profile change related?. Complaints told me this.

        "We value your service with us and we will do our best to assist you the best way possible. After investigating, I see that there is outage in the area, affecting the services. While the outage is being fixed we are unable to process any diagnostics hence I appreciate you time and patience while our engineers are working on priority to fix the issue. In relates to the outages, I would like to advise you that the outages sometimes are planned to make the services better and sometimes unplanned. You may also get an update on an outage in the area by registering your number on the outage communicator".

        This was 2 weeks ago what does this mean please? It's getting worse so is there a ticket number or anything, might the numerous profile changes have something to do with this, I was ok on us profile 11 now im back to 11 13 what ever that is now its dropping Modulation again, ksps symbol rate doesnt add up. Any answers from virgin would be appreciated.

      Hi Viper-t, 

      Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums.

      We're sorry to hear you've been having an issue with your network. Taking a look at things here we can see your signal levels are too low and the downstream power levels are also a little high. We won't be able to fix this remotely so I would like to arrange for an engineer to come to take a look at this for you. 

      I just need to confirm the address to ensure we are booking the visit on the correct account. I have sent you a direct message to allow us to do this with you in a private space. If you are using a PC/Laptop then you can just click on the little ✉ at the top right-hand side of the page to access your inbox. If you are on a mobile/tablet device then instead click on the little circle icon in the top right then select 'Messages'. 😊

      Thanks,

        Hi Kath so my power levels are in spec according to virgin +10, docsis standard is +7 anyhow, so what's wrong with all the profile changes for all of us and packet loss please? As my power is in spec yet I am seeing the same packet loss and huge t3 counts and upstream Ranging problems on channel 3,4,8 I don't have a channel 8 for upstream. I'm still getting profile changes every 3-5 minutes. Is there an area fault? 

        Regards
