I've been having issues with my hub3 200mb connection recently. I get random lag spikes whilst gaming. I have contacted virgin media and they said they are putting my connection under monitor and would contact me straight away when they observed any issues.
The hub is in router mode as it's required for them to monitor but I'm still having the random lag spikes and nothing seems to be solved as of yet. I made a post not long ago and we setup a thinkbroadband monitor which didn't really show anything on it.
I've attached router logs as suggested on other posts.
I'm really sorry to hear that you're having issues with your connection, I have been able to locate your account from your community profile.
I cannot find anything that would be causing the issues that you're having, I can see that your hub hasn't been rebooted for a month, please could you try to do this and let me know if it improves your connection at all.
If not we can then get this looked into further for you.
