Help interpreting my BQM

Hi - I'm on Virgin SHub 2. I have a SHub 3 but have not connected it for fear of gaming issues.

Just recently my speed was increased (200mb+) but I've been having drop-outs on wifi and lan. VM engineer cam round yesterday, replaced an attenuator, we did a speedtest and got:

ping: 11, D/L: 230, U/L 12

I then checked it later and D/L had dropped to 1!

So I set up a BQM, but I'm not sure how to interpret it. Note, 1 am is when I switched by PC off. Not sure why packet loss spikes heavily there?

Spiking when PC is off may be the superhub knowing not much is connected so no giving priority to replying to pings

Other than the spike of packet loss at 8pm from then to 1am the graph looks good for a cable connection i.e. the usual jitter

Thanks. It's odd because the PC was turned off around the same time last night and there's no major spiking this time.

Also, there appears to be some consistent, low-level packet loss. Is that normal/acceptable?

Does this packet loss show up when you ping a host for a period of time?

i.e. need to double check its not just an oddity in how the router is handling the ping replies to the ping box

HI MrSaffron - how would I test that, please? Just repeatedly ping 8.8.8.8 or something for a few mins, or use some kind of tool?

I will have time to do this at the weekend.

By the way, the problems I've been having can be seen in this BQM - from around 10 pm the connection was terrible. Router power cycled today at just gone 10.15 and packet loss stops all of a sudden.

My Broadband Ping

ping -n 100 pingbox1.thinkbroadband.com

The 100 is how many pings, and then when it finishes it displays a summary, need to use a common prompt window, since if run from the RUN prompt the window closes when finished.
