Awful Unreliable Connection with Dropouts (Modem Only Mode)

Poverty

Can someone take a look at these logs and provide what's happening here?

Today had far too many outages. HUB3 in modem only mode. Devices are wired. Router seems to reboot every few minutes.

Never really had any reliable service from Virgin Media and even switched to Virgin Media Business but they never fixed anything (horrendous customer service and held me to their 2 year contract) and just keep saying area faults and left back for residential (100MB). I've had 5 years of this and now as 4G has got a lot cheaper I'll have to attempt to try a failover with 4G on 02 & this 100MB connection.

Virgin media for home don't offer 4G backup services, and I don't want to try a business connection again with the 4G backup as i'll be forced into a 2 year contract even if their service is constantly offline and no amount of complaining will fix the problem.

The area must be over capacity and the network just can't handle the volume of customers.

Unfortunately got no Fibre to go down the BT route 😞

Hi Poverty,

Thanks for coming back, it looks like there is a SNR issue in the area which is causing the drops you are experiencing, this was picked up on 18/11/21 and the estimated fix date is 25/11/21 SNR Signal to Noise Ration can cause the below?

You might find that your Virgin Fibre, Voice and Virgin TV services are intermittent, with the picture freezing or disappearing now and then. We are sorry and our engineers are working hard to resolve this for you, apologies for any inconvenience caused.

Regards

Paul.

 

Now what is the problem?

Hi @Poverty,

Thank you for coming back to us. I'm sorry to see that you're experiencing some disconnections again! I understand that this is not ideal at all. 

I was able to locate your account and run through some checks for you to ensure that there are not faults impacting your services. I cannot see any area issues or problems with your power levels. However, I can see that your Hub uptime is showing as 30 days at the moment. We would advise rebooting your Hub to see if this can help with your disconnection problems. 

You can also take a look at our Broadband Faults page to run some further checks on your equipment.  

Thank you.

Nothing was sorted last time, now getting serious dropouts again and it's been offline 12+ hours.

Had enough - Finally Openreach have upgraded the area so I can get Fibre!

Only a month to wait for disconnection, can't wait!

Hi Poverty,

Sorry to see that you're having ongoing issues again, we can certainly understand your frustration with this. 

Remotely checking our systems, we can see that you're currently experiencing some downstream power level issues. 

Due to this, we would need to book an engineer out to come and resolve this issue for you.

Would you be happy for us to do this?

Please let me know, and I will get this arranged for you.

Kind regards Jodi. 

For anyone intrested - look at this graph the difference. Exact same router but on an FTTP connection with TalkTalk and should be rock solid according to the engineer that installed it in comparison to Virgin.

Couldn't be happier that it's now installed and Virgin has been cancelled (a 6 year wait for an alternative provider).

IP changed when I rebooted the router at 9:30pm incase you were wondering 😛

We're sorry to see you have left us. We do wish you all the best with your new provider.

I'm sure one day VM will go fibre with better and fastest tech comes around to put a end to copper
