Severe lag spikes and packet loss.

I have been connected with Virgin at my current property for just under a year now, and the connection has been great! Recently I got upgraded from the Hub3 to the Hub4, and that also went smoothly. I have been on the Hub4 for a month or so now.

However within the past few days I have been having extreme lag spikes, and it makes playing any sort of games impossible. I usually hover around 40ms ping, and then have long periods of 200+ms.

I have looked around and seen similar posts before so I have gone ahead and already set up the BQM https://www.thinkbroadband.com/broadband/monitoring/quality/share/7e2c642842a74b0cfa26129d39032b1c2e....

I will post the Network Configuration settings from the router in subsequent comments to this post. Hopefully someone can take a look and identify what might be going on. I don't know if its related, but it does feel like this has started as the weather has recently taken a turn, but i wouldn't have thought this would be the cause?

At least half of your Downstream Power Levels are too hig...

At least half of your Downstream Power Levels are too high.

This will need an engineer to put right.

You can either phone in (08:00 is the best time) or wait on here for a few days (6 to 7 days average) until one of the VM Forum Staff comes along.

If you wait on here Do Not bump the thread it will put it further down the VM 'to do list'.
