For both work and personal use, out service has been very poor for the last few days. We seem to be dropping multiple packets during Teams / Zoom / Online games etc. 

I've a VM 4 Hub, set up with a To Link Deco wireless system. I've run a few pings directly from the Hub4 and get various different timeout errors intermittently. 

Anyway, Monitor is here:

 Will post other stats in next few posts.

I'm afraid you are suffering from the same problem as everyone else on here complaining of poor service. It's caused by millions of users all wanting to use the network for two-way video and other WFH uses. The network wasn't designed for that, and just can't cope.  OFCOM say that broadband use has increased by 100% over the lockdown, and Virgin have mentioned 95%.

Thanks, it's generally ok most of the time, but when it's bad it's utterly unusable. 

I suppose with this week being half term the kids are probably saturating the network as well. 

It's slightly frustrating as I've no FTTH / poor FTTC in my area, so no real alternative to VM over 100mb.
