What is your connection like with a direct connection using a Cat 5E/6 cable between the Hub and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?
The problem with Wi-Fi is that it can be brilliant at breakfast time and useless by lunchtime and you haven't changed anything, BUT, something somewhere has changed, then you can spend hours and even days trying to find a fix for something that can be totally out of your control.
if you remove all the internal walls, electronic and electrical devices, metallic pipes and conduits and wrap the whole building in a thick lead shield you will have a good chance of getting decent Wi-Fi from a VM Hub.
Many people have accepted that the VM Wi-Fi is very poor and have purchased third party equipment that is much, much more powerful than the VM supplied kit and once set up have wondered why they waited for so long.
You really do need to check with a direct connection using a Cat 5E/6 cable between the Hub and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected, otherwise you won't know if it is a broadband supply problem or a local Wi-Fi problem.
If it is a broadband problem no amount of boosting will get better internet over Wi-Fi.
I was just asking for the same info that the original poster asked for. Wanted to indicate my interest too. Didn't really see much point in creating a new thread to ask the exact same thing... but I guess if that's the only way...
