Lag spikes and dropped packets

Could someone take a look and advise please?

Lag spikes increasing over recent months, noticeable when gaming but also some buffering on streaming services.

There was an Email in June about a  network upgrade completion. Everything stable since Virgin replaced SH3 with SH2AC back in 2017.

All connection checked, last router reset around Midnight 13th.

Something feels flaky.

Hello weirdbeard12

 

Thanks for posting in regards to the connection issues you're experiencing, we appreciate you raising this via the forums and welcome to the community.

 

We've had a look at the connection from our side but the information is limited due to the Hub being in modem mode, that being said there aren't any area issue reported for your area at the moment. If you are still experiencing the issues can you take the Hub out of modem mode so we can see some more details?

 

Rob

Thanks Rob, appreciate you taking a look.

Will take Hub out of modem mode later this evening and post again to update you.

That would be brilliant, thanks weirdbeard12.

 

Just let us know once you've done that so we can check for you 🙂

Hi Beth

Hub now reset to Router mode.

BQM now reflects new IP address.

Hi weirdbeard12,

 

Thanks for putting the hub into router mode for us - it looks like the hub has a very long uptime and hasn't been rebooted in a while. Can you please reboot the Virgin Media hub and let us know once you've done that? I will check the status of your connection again from here 🙂

 

Thanks

 

 Beth
