Packet Loss Spikes

I set up my Broadband Quality Monitor yesterday. The graph for the last 24 hours shows a large spike of packet loss, not at random, but at regular intervals . I am also experiencing intermittent loss of internet connection.

My question is why is my router losing packets at regular intervals rather than randomly? Does this suggest anything definite that I can talk to the internet provider about?

Can you link to the graph so that we can see it?

Also, is there anything in your house on a regular timer? Local interference could cause spikes - or it could be something along the route that turns on at regular intervals and causes interference to the line. But, seeing the graph may help us.

SamKnows boxes produce regular spikes due to the regular testing that goes on too.

Hadn't thought of that. Have a Samknows box but afraid I don't use the BQM...

Here's a link to my broadband activity. As you can see, I hope, there are regular spikes of packet loss.

Can you make sense of it please?

As MrS suggested, do you have a Samknows box?

No. I've no idea what a Samknows box is.

We have nothing in the house that is switching on at regular intervals, day and night. The fridge stays on all the time, but it switches on irregularly of course. I can't think of any reason for the regular interruption of my wifi connection - at least nothing under my control.

NOTE: The BQM is NOT testing your wireless but the cable modem link up to the cable modem (or router if running modem in bridge mode)

Does that mean the information on the BQM graph is absolutely useless in establishing why the internet connection is intermittent?

If you have seen the graph I posted on the forum this morning, can you suggest any reason why the packet losses are so regular and whether that's a clue to the loss of my internet connection? I was intending to show the graph to the Virgin Media technician when he comes tomorrow.

Thanks in advance.

Hadn't realised it is Virgin. I believe there were some issues with the Virgin Superhubs that could cause that on graphs in the past but I'm not with Virgin so no personal experience. The way Virgin works is very different to FTTC so may change people's thoughts on the issue.
