Packet Loss issues

Currently using Virgin Media Hub 3, with M250 Fibre Broadband, connected via ethernet. Every few days I have been experiencing packet loss issues that are very noticeable especially when gaming. I have checked my postcode using the automated phoneline and the app; there are apparently no issues.

I have just now set up a BQM so it will only have the past hour or so of data but here it is:

I have been getting the following network log issues:

  • DHCP RENEW WARNING - Field invalid in response v4 option
  • No Ranging Response received - T3 time-out
  • RCS Partial Service
  • SYNC Timing Synchronization failure - Loss of Sync

Downstream (maybe power issues?):

Upstream (32 qam?):

If you have any solutions or need more information please ask. 
Thank you,

All Downstream power levels are far too high.  

All Upstream power levels are too low, and one channel is degraded to QAM 32.

Has a 10dB Wideband attenuator been removed from the connection to the Hub ?


Downstream
Power Levels of -7 to +7 dBmV are preferred, +10dBmV is the max acceptable, with a SNR of 33dB or higher across all DOCSIS 3.0 channels. Rising error counts across many channels is a current service noise fault.

Upstream
Power Levels of 35 to 49 dBmV are preferred, with QAM 64 Modulation mode across all four to six DOCSIS 3.0 channels.  Seeing QAM 32/16/QPSK is a current service noise fault.  Seeing less than four DOCSIS 3.0 channels is usually a signal level fault.

Hi, Thanks for replying 

not sure if this is what you are referring to?

Hello RM04/

Thanks for your post and welcome to our Community.

Sorry to hear about the packet loss.

Looking at your pictures I would say this is a self installation and the power levels need tweaking a bit.

I did run a test on your hub and can see both upstream and downstream levels are out.

It would need an engineer to attend, which I can arrange from here.

If you don't mind, I will need to send you a private message to pass security. 
If you can check the Logo top right of your screen that would be great.

Hi Gareth_L,

I still haven't received a reply from you since Thursday. Please can someone else from the forum team take over this case or bump Gareth_L. I need to get this packet loss fixed as soon as possible.
