If possible can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

What speeds do you get at >> Sam Knows Real Speed << with a direct connection using a Cat 5E or better ethernet cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?
Apparently, only Sam Knows Real Speed can measure your true speed on Super Hub 4 following a call i made to their Tier 2 team.
However, it would have been nice if this was mentioned on the VM website as they do recommend to use www.speedtest.net, which is what i used and subsequently this reported a lower speed. Whether or not this is 100% accurate is something we will never know as we are at the mercy of being advised this.
Why they could of not told me that yesterday during the numerous calls i made to them is beyond me.
Come on VM. Your service is generally good until you need to contact Tech Support then a customer then has a very bad experience.
