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.

What are my next steps?

You also have loads of post-rs errors ( you should not have any)

You could set up a broadband monitor from think broadband and then post the link to it here.

It would have up see what's going on.

 Here is my monitoring chart I've just set up.

Good job, now lets give it a day or so to gather data.

Hi @96fauj,

Thanks for taking the time to post on our forums.

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. 

Regards,

Steven_L

@Steven_L : Will do, I'll give it a reboot although it's worrying that it's reporting that this hasn't been done for a month. Either way, I'll reboot it and see how I get on next 1-2 days.

@risc19 : Thanks for your help too, I guess we can monitor the graph. I had a look this morning and it looks reasonable as the pings aren't spiking that hard? you probably have a better idea.

[Steven_L]

Thanks for coming back to us so quickly @96fauj.

Please share your BQM in the next few days and we can look into this further.

Regards,

Steven_L
