Intermittent connection

Hi,

Really hoping I can finally fix this with some help from here.

For months we've experienced intermittent connection and buffering even with wired devices. Getting dropped packets and high latency. It's intermittent, at random times of the day. Cutting out on Skype and Teams calls is getting bad. For wireless connection I tend to have to switch off WiFi and reconnect to the hub. And I'm in the same room as the Hub and it doesn't matter what device I'm using.  The call centre have been useless in the past recommending we switch off the router multiple times a day to reboot it - which didn't work.

Can someone from Virgin please fix this. The service is simply not good enough.

My BQM, for an average day (sometimes it's better, sometimes it's worse):

Like I said, this week it's the best it's been for months, but it's cut out on a few important Skype calls so I'm forced to do something about it.

This is what a good day looks like. You can still see a few short periods of packet drops and PingOuts:

And here's the logs from the Hub:

Re: Intermittent connection

A lot of your Downstream Power Levels are on or over max levels and will require an engineer to put them back into spec.

Re: Intermittent connection

Good to know, thanks.

Worth pointing out too that the whole district has had problems for a year now. Neighbours, friends and family locally have the exact same intermittent issues as me. Back last Summer they took the whole district offline for days to trace a problem...Nothing changed.
