Packet Loss & Internet Dropouts

Following on from my previous post from a couple of months ago (https://community.virginmedia.com/t5/Networking-and-WiFi/Random-loss-of-Internet-connection-RCS-Part...) I am once again suffering from significant packet loss and drop outs likely as a result of RCS Partial Service messages:

Latest Examples:

Re: Packet Loss & Internet Dropouts

Your BQM is a mess.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Your Pre & Post RS Error counts are very high.

In an ideal world they would be at zero and stay there. To zero them can you reboot the Hub using this method and then keep an eye on the counts.

Switch the Hub off using the small switch on the rear of the Hub next to the power cord and pull the PSU plug from the wall socket.

Give it a good 5 minutes put the plug back in and switch the Hub back on.

Allow the Hub a few minutes to fully restart then check the counts again in an hour or so.

Re: Packet Loss & Internet Dropouts

Hi Noveske,

I am sorry to hear this and I have checked and your downstream levels are low, you need a tech. I will pop you over a private message and take a look for you. Just keep an eye out for the purple envelope.
thanks,
Zoie
