Welcome to the forum and sorry to hear you're having trouble with WoW. Thank you for posting all the info and running all those traces. Everything looks good from the stats you've posted and I've checked from this side too to make sure. Your network segment looks healthy, low contention and stable SNR.
The traces you've posted all return good ping times and complete with no problems. It's normal for battlenet servers to ignore ping requests which is why the last entries are all starred out.
We've been extra vigilant on the WoW front recently as we've seen quite a few similar posts in the last week or so but almost all of them have been connection specific so far.
So we can try and narrow down the possible causes a little further could you try the hub in modem mode with a PC in safe mode with networking? This will eliminate the router portion of the hub, other devices on the network and any background programs on the PC as the possible culprit.
Let us know how you get on and we'll do what we can to get this working
"We've been extra vigilant on the WoW front recently as we've seen quite a few similar posts in the last week or so but almost all of them have been connection specific so far."
Yeah, because innumerable gamers magically developed localised connection issues all in the exact same week, right? What a spectacular coincidence!
Let's not beat around the bush, most of the people reporting gaming issues here, are clearly being affected by a centralised issue, i.e. an issue with VM's network management. That's the real problem here, and it's a problem you better fix pronto, or you can wave goodbye to a myriad of your paying customers.
