WiFi/Ethernet constant disconnect and high ping/packet loss

Hi,
I recently got virgin media at my property and I've been getting constant high latency and packet loss, and my WiFi/Ethernet seems to disconnecting randomly for a few seconds, which happens on all the devices but not at the same time. I tried using the Ethernet cable which still has the same issue.

When the disconnect happens, the windows network icon shows the little globe, so it's not completely disconnecting and it says something about DNS not being configured properly.

I have reset the router multiple times with the pin-hole reset, I also disabled channel optimization under Smart WiFi, tried splitting the WiFi into 5GHz and 2.4GHz  under Advanced Settings->Wireless Security however the issue still persists.

I have attached the network status logs below and my BQM is here

https://www.thinkbroadband.com/broadband/monitoring/quality/share/85fd73fd3303b3e36855e0950e8e8b8fa668ddbe

It mostly happens when I'm gaming and you can see the packet loss spike on the graph when I was playing Warzone. I only 2-3 matches to make sure it's not the server and it still persisting.

Re: WiFi/Ethernet constant disconnect and high ping/packet loss

Upstream power levels are too high, you need a technician’s visit to rectify. Phone customer services or wait a day or two for a VM staff member to get to your post and arrange a technician.

The engineer came to take a look and he did something at the cabinet but it doesn't seem to be fixed.

Hello @6XWJo388n6.

I am sorry that your issues have not yet been resolved.

 

I have emailed the area field managers for your area, I am waiting for one of them to get back to me with what we can do.

Re: WiFi/Ethernet constant disconnect and high ping/packet loss

Hi @Hayley_S,
They swapped the router to a new one and it looks like the issue is fixed or at least I'm not experiencing disconnects as frequently (a random device would sometime disconnect once a day now at most), although I am getting some lag spikes sometimes, not sure if this is related or if it's just the game servers.

Re: WiFi/Ethernet constant disconnect and high ping/packet loss

Thanks for the update and glad to hear replacing the router has resolved the issue for you 6XWJo388n6.

 

Do the lag spikes happen in one particular game? Or any that you play? What device are you gaming on? PC or console?

 

As you say, it may be the game servers that are the issue if this isn't happening constantly/ever game and if it is multiplayer you're playing.

Re: WiFi/Ethernet constant disconnect and high ping/packet loss

Hi Robert,

It seems to be every game, I'm playing on a Desktop PC and i tried with Ethernet and WiFi and it seems to be the same. 

It's not constant high ping, on almost all the games I get around 25ms ping but sometimes it jumps to over 200ms.
