Hub 3.0 keeps dropping Teams and vpn connection

[billyhl]

Trying to work from home with 500Mbps broadband package but for the past several Months I am having severe issues with Hub 3.0 and my vpn work connection so much so that I have now got a secondary 11Mbps ADSL line that works better (Seriously no Dropouts), this has been affecting me WFH and also my work only has so much patience with "broadband problems".

On teams and VM connection callers take 10-15 seconds to be able to hear me but I can hear them straight away and I keep getting "Poor Network Quality" coming up all the time (LAN connection NOT Wi-Fi), I have no such problems on the "Backup Broadband" as I like to call it but it is actually my GOTO broadband at the moment

I have opened complaints with VM and keep getting Fobbed off with dates this will be fixed and TBH I am thinking of dumping VM all together, I shouldn't have to endure Months of poor service and have to turn to VM forums for "Assistance", also I am paying a high price for this lack of service and No "Compensation", I have been told by a couple of people that my area is over subscribed and this is what is causing the issues.

I noticed that some people had asked for the hub downstream logs so I have attached this if it helps anyone to try and figure out what is happening to my connection.

Thanks in advance for anyone taking the time to help or point me in the right direction.

One channel looks bad.

Does hub in modem mode with a PC run any better?

Thanks for the reply legacy1

No idea what "Does hub in modem mode with a PC run any better?" means or how to configure it?

And yes the whole thing is bad to me.

Losing the will sometimes with this VM connection.

Thinkbroadband graphic has some lovely colour's for the last 24hrs

Can anyone interpret this? Could this be my problem?

[legacy1]

yes your line is clipping at a given intervals likely a problem out side.

Wow! 2 Days and no VM staff responses?

Finally had enough last night and after an email telling me that my "Services" were going up by £7 per month from May and increasing by 3.9% every year plus the rate of inflation I decided to call the disconnection team and give my 30 day notice, nice little end bit on the email stated that if I was unhappy and did not wish to continue I could leave without any penalty as long as I telephoned before March 23rd, So I did just that, funny thing is that I had VM chasing me today and have an engineer calling on Friday to sort my broadband out apparently.

Will this change my mind after the months of attempting communication and telling VM constantly that I am still having problems, after raising complaints about the service and having no compensation for a 500Mbps service being outclassed by an 11Mbps ADSL connection that has never let me down? 

I of course will give the engineer the courtesy of fixing the problem if possible but already I am looking at 4G/5G networks in my area at a fraction of the cost of VM as I already have a 5G Router, I can get unlimited data sims from @£16 per month and am within eyesight of masts if I wanted a fixed antenna for better signal strength.

Really not impressed with no reply's to  any form of communication that I put to VM before the disconnection call, once that call had taken place at least I finally have someone actually call me and arrange an engineer.

The thinkbroadband graphic is still a joke with colours.

Thanks for the response's legacy1 appreciated you actually took the time out to reply.

After checking that none of your coax cables are loose (which potentially fits the non-correctable errors (post-RS), you could ask a neighbour or two if they have the same sort of issue.

You may have more than one problem namely channel 12 is the main offending DAB radio ,interference channel. Normally it shouldn't affect you because your cables are shielded. But a loose connection anywhere between your Hub and the street box would allow noise in.

But your BQM is difficult to interpret. The upstream stats aren't great and the 23.6MHz channel has noise that causes the modulation to fall from 64QAQM to 32QAM. However from moment to moment, that could really be flapping. Ordinlrily, taking it all together, it would suggest a loose cable somewhere on your line. But the periodicity of the BQM is a puzzle.

Keep us posted after the tech has been.

VM can take several days to reply on here as it isn't a direct support channel. You need to contact them by phone if you want a faster response.
